Executive Summary 

Sarasota Bay and Peace and Myakka Rivers 

The Water Quality Assessment Report for the Sarasota Bay and Peace 

and Myakka Rivers Basin is part of the implementation of the Florida 

Department of Environmental Protection’s (Department’s) watershed 

management approach for restoring and protecting water resources and 

addressing Total Maximum Daily Load (TMDL) Program requirements. 

A TMDL represents the maximum amount of a given pollutant that a 

waterbody can assimilate and still meet the waterbody’s designated uses. A 

waterbody that does not meet its designated uses is defined as impaired. 

The watershed approach, which is implemented using a cyclical management 

process, provides a framework for implementing the requirements of 

the 1972 federal Clean Water Act and the 1999 Florida Watershed Restoration 

Act (Chapter 99-223, Laws of Florida). 

A Status Report, published during Phase 1 of the watershed management 

cycle, provided a Planning List, or preliminary identification, 

of potentially impaired waterbodies in the Sarasota Bay and Peace and 

Myakka Rivers Basin. This Assessment Report presents the results of 

additional data gathered during Phase 2 of the cycle. The report contains 

a Verified List of impaired waters (Table 4.3 in Chapter 4) that has been 

adopted by Secretarial Order and approved by the U.S. Environmental Protection 

Agency (EPA). TMDLs must be developed and implemented for 

these waters, unless the impairment is documented to be a naturally occurring 

condition that cannot be abated by a TMDL, or unless a management 

plan already in place is expected to correct the problem. The Verified List 

also constitutes the Group 3 basin-specific 303(d) list of impaired waters, 

so called because it is required under Section 303(d) of the Clean Water 

Act. See Noteworthy in Chapter 1 for a description of the contents of this 

report, by chapter. 

In the Sarasota Bay and Peace and Myakka Rivers Basin, state, federal, 

regional, and local agencies and organizations are making progress towards 

identifying problems and improving water quality. Through its watershed 

management activities, the Department works with these entities to support 

programs that are improving water quality and restoring and protecting 

ecological resources. The Department’s TMDL Program objectives will be 

carried out in the basin through close coordination with key stakeholders 

such as the following: 

Sarasota Bay—Southwest Florida Water Management District 

(SWFWMD); Sarasota Bay National Estuary Program (SBNEP); and 

Manatee, Sarasota, and Charlotte Counties; 

Peace River—SWFWMD; Charlotte Harbor National Estuary Program 

(CHNEP); and Polk, Hardee, DeSoto, and Charlotte Counties; and 

Myakka River—SWFWMD; CHNEP; Myakka River Management 

Coordinating Council; Myakka Wild and Scenic River Management 

Program; the Department’s Division of Recreation and Parks; Charlotte

10 Water Quality Assessment Report: Sarasota Bay and Peace and Myakka Rivers 

Harbor Aquatic and State Buffer Preserves Program; Manatee, Sarasota, 

and Charlotte Counties; and the cities of North Port and Port Charlotte. 

Coordination with the many other initiatives in the three-basin area 

is essential to the success of TMDL efforts. These initiatives include 

SWFWMD’s Sarasota Bay and Charlotte Harbor Surface Water Improvement 

and Management Programs, as well as its Comprehensive Watershed 

Management Program for each basin, the SBNEP and CHNEP, and the 

Sarasota Bay and Charlotte Harbor Aquatic and State Buffer Preserves 

Programs. 

Not only do stakeholders in the basin share responsibilities in achieving 

water quality improvement objectives, they also play a crucial role in 

providing the Department with important monitoring data and information 

on management activities. Significant data providers in the three 

basins include the city of Lakeland; Manatee, Sarasota, and Polk counties; 

Florida LakeWatch; Peace River/Manasota Regional Water Supply 

Authority; Florida Phosphate Council; SWFWMD; Department; and U.S. 

Geological Survey. 

During the next few years, considerable data analysis will be done to 

establish TMDLs for impaired waters in the Sarasota Bay and Peace and 

Myakka Rivers Basin, establish the initial allocations of pollutant load 

reductions needed to meet those TMDLs, and produce a Basin Management 

Action Plan to reduce the amount of pollutants that cause impairments. 

These activities depend heavily on the active participation of the 

water management district, local governments, businesses, and other stakeholders. 

The Department will work with these organizations and individuals 

to undertake or continue reductions in the discharge of pollutants and 

achieve the established TMDLs for impaired waterbodies. 

Summary of Findings 

The Department’s assessment shows that 94 waterbodies or waterbody 

segments in the Sarasota Bay, Peace River, and Myakka River Basin 

Group are impaired and require the development of TMDLs. The following 

summarizes, by planning unit, impairments by waterbody types and 

the primary pollutants. Planning units are smaller areas in the basin that 

provide a more detailed geographic basis for identifying and assessing water 

quality improvement activities. 

Sarasota Bay Planning Unit 

Of the 78 waterbody segments in the Sarasota Bay Planning Unit, 

59 segments have sufficient data for some surface water quality parameters 

for assessment. Of these, 31 are verified impaired for at least 1 parameter 

assessed and will require TMDLs, 19 remain on the Planning List, and 

9 meet standards for at least 1 parameter. 

The majority of the segments are impaired for mercury because of 

elevated mercury levels in fish tissue. The coastal waters of the Gulf of 

Mexico have fish consumption advisories for a number of marine species 

due to high levels of mercury in fish. Water segments are also impaired due 

to nutrients and coliform bacteria.


11 

Upper Peace River Planning Unit 

Of the 193 waterbody segments in the Upper Peace River Planning 

Unit, 78 segments have sufficient data for some water quality parameters 




The majority of the impairments are due to nutrients in the lake 

segments in the areas of Lakeland and Winter Haven. 

Middle Peace River Planning Unit 

Of the 94 waterbody segments in the Middle Peace River Planning 





A mainstem of the Peace River is impaired for mercury because 

elevated levels in Largemouth Bass exceeded the Impaired Surface Waters 

Rule threshold for listing and Chilton Lake is impaired for nutrients. 

Lower Peace River Planning Unit 

Of the 35 waterbody segments in the Lower Peace River Planning 





The most common parameters of concern are nutrients, dissolved 

oxygen (DO), and mercury in fish. The estuarine portions of the Peace 

River are listed for mercury due to the fish consumption advisories for a 

number of marine species in the Gulf of Mexico coastal waters. 

Upper Myakka River Planning Unit 

Of the 27 waterbody segments in the Upper Myakka River Planning 

Unit, only 4 segments have sufficient data for some water quality parameters 


assessed and will require TMDLs, none are on the Planning List, and 

none have sufficient data to determine if standards are met. 

The parameters of concern are coliform bacteria in the Upper 

Myakka River and Owen Creek and DO in the Upper Myakka River and 

Howard Creek. 

Lower Myakka River Planning Unit 

Of the 53 waterbody segments in the Lower Myakka River Planning 




1 meets standards for at least 1 parameter. 

The most common impairments are for nutrients and DO.


Documentation of Reasonable Assurance 

The SWFWMD, in cooperation with the Florida Department of 

Agriculture and Consumer Services (DACS) and local agricultural stakeholders 

in the lower Peace River Planning Unit, developed a watershed 

management plan to address the impairment of designated uses in the Shell 

and Prairie Creek watersheds related to total dissolved solids, chlorides, and 

specific conductance. The Department concluded that the management 

plan provides reasonable assurance that the impairments will be adequately 

addressed. 

Based on the documentation provided, the Department specifically 

concluded that there is sufficient reasonable assurance of the following: 

1. Completed and proposed management actions in the plan will 

result in the attainment of total dissolved solids, chlorides, and 

specific conductance criteria in the following water segments: Shell 

Creek (waterbody identification number [WBID] 2041), Myrtle 

Slough (WBID 2040), and Prairie Creek (WBID 1962), and 

2. Reasonable progress towards continued attainment of the narrative 

nutrient criteria and associated designated uses will be 

made through 2009, which is the year that the next 303(d) list of 

impaired waters for the Peace River Basin is due to be submitted to 

the EPA. 

Key financial and technical support for implementing the plan is 

being provided by DACS, the SWFWMD, and the U.S. Department of 

Agriculture. When fully implemented, the plan will likely be one of the 

most successful water quality restoration projects in the state.

Chapter 1: Introduction 

Purposes and Content of the Assessment 

Report 

The Florida Department of Environmental Protection (Department) 

is implementing a statewide watershed management approach for restoring 

and protecting water quality and addressing Total Maximum Daily Load 

(TMDL) Program requirements. Under Section 303(d) of the 1972 federal 

Clean Water Act and the 1999 Florida Watershed Restoration Act (FWRA) 

(Chapter 99-223, Laws of Florida), TMDLs must be developed for all 

waters that do not meet their designated uses (such as drinking water, 

recreation, and shellfish harvesting) and are thus defined as impaired. 

TMDLs will be developed, and the corresponding reductions in 

pollutant loads allocated, as part of the watershed management approach, 

which rotates through the state’s 52 river basins over a 5-year cycle. Extensive 

public participation from diverse stakeholders in each of these basins is 

crucial in all phases of the cycle. 

A Status Report published during Phase 1 of the watershed management 

cycle provided a Planning List, or preliminary identification, of potentially 

impaired waterbodies in the Sarasota Bay and Peace and Myakka 

Rivers Basin. A copy of the report can be found at http://www.dep.state 

.fl.us/water/tmdl/stat_rep.htm. 

This Water Quality Assessment Report, which updates the information 

in the Status Report, incorporates data collected from the Department’s 

strategic monitoring and gathered from other agencies and groups during 

Phase 2 of the watershed cycle. The report contains a Verified List of 

impaired waters required by the FWRA and Section 303(d) of the federal 

Clean Water Act, for which TMDLs must be developed and implemented 

(see Noteworthy for a description of the Assessment Report’s contents, by 

chapter). Based on the assessment results, in the Sarasota Bay and Peace 

and Myakka Rivers Basin 94 waterbodies or waterbody segments are verified 

impaired for 1 or more parameters. TMDLs must be developed for 

these waters, unless the impairment is documented to be a naturally occurring 

condition that a TMDL cannot abate, or unless a management plan is 

already in place to correct the problem. 

This report is intended for distribution to a broad range of potential 

stakeholders, including decision makers in federal, state, regional, tribal, 

and local governments; public and private interests; and citizens. 

The Verified List is required by Subsection 403.067(40), Florida 

Statutes, and Section 303(d) of the federal Clean Water Act. The Department 

has adopted the Verified List of impaired waters in accordance with 

the FWRA and the Identification of Impaired Surface Waters Rule (Rule 

62-303, Florida Administrative Code). The U.S. Environmental Protection 

Total Maximum 

Daily Load 

The maximum amount of a 

given pollutant that a waterbody 

can assimilate and 

remain healthy, such that all 

of its designated uses are 

met.


Agency (EPA) has also approved this list as the current 303(d) list of 

impaired waters for the basin, so called because it is required under Section 

303(d) of the Clean Water Act. 

The first 303(d) list, which was required by the EPA in 1998, is to 

be amended annually to include basin updates. Florida’s 1998 303(d) 

list included a number of waterbodies in the Sarasota Bay and Peace and 

Myakka Rivers Basin. Tables 3.5 through 3.10 in Chapter 3 list these 

waters, by planning unit. 

This Assessment Report follows the EPA’s guidance for meshing 

Clean Water Act requirements for Section 305(b) water quality reports 

and Section 303(d) lists of impaired waters. The integrated water quality 

assessment is used to identify the status of data sufficiency, the potential for 

impairment, and the need for TMDL development for each waterbody or 

waterbody segment in the basin. 

Appendix A describes the legislative and regulatory background for 

TMDL development and implementation through the watershed management 

approach, and briefly explains the TMDL Program. Background 

information on the Department’s TMDL Program, the process of TMDL 

development and implementation, lists of impaired and potentially 

impaired waters, and assessments for other parts of the state are available at 

http://www.dep.state.fl.us/water/tmdl/index.htm. 

Stakeholder Involvement 

The FWRA requires the Department to work closely with stakeholders 

to develop and implement TMDLs. In addition, the Department’s 

Allocation Technical Advisory Committee (ATAC) report, submitted to 

the legislature, recommends relying on stakeholder involvement. Stakeholder 

involvement in the TMDL process will vary with each phase of 

implementation to achieve different purposes (Table 1.1). A copy of the 

ATAC report is available at http://www.dep.state.fl.us/water/tmdl/docs/ 

Allocation.pdf. 

The Department will work cooperatively with a number of key stakeholders 

to develop, allocate, and implement TMDLs in the Sarasota Bay 

and Peace and Myakka Rivers Basin. These include the following: 

Sarasota Bay—Southwest Florida Water Management District 

(SWFWMD); Sarasota Bay National Estuary Program; and Manatee, 

Sarasota, and Charlotte Counties 

Peace River—SWFWMD; Charlotte Harbor National Estuary Program 

(CHNEP); and Polk, Hardee, DeSoto, and Charlotte Counties 

Myakka River—SWFWMD; CHNEP; Myakka River Management 

Coordinating Council; Myakka Wild and Scenic River Management 

Program; the Department’s Division of Recreation and Parks; Charlotte 

Harbor Aquatic and State Buffer Preserves Program; Manatee, Sarasota, 

and Charlotte Counties; and the cities of North Port and Port Charlotte

management objectives and issues of concern; develop a Strategic Monitoring Plan; 

and produce a preliminary Status Report that includes a Planning List of potentially 

impaired waters 

Cooperative efforts between the Department and local stakeholders to collect additional 

data; get data into STORET (the EPA’s national water quality STOrage and 

RETrieval database); complete water quality assessment; produce a final Assessment 

Report that includes a Verified List of impaired waters for Secretarial adoption; 

and provide an opportunity for stakeholders to document reasonable assurance (for 

Department review) that existing or proposed management plans and projects are 

adequate to restore water quality without the establishment of a TMDL 

Coordination with stakeholders to discuss TMDL model framework, including model 

requirements, parameters to be modeled, model endpoints, design run scenarios, and 

preliminary allocations; communication of science used in the process; public workshops 

for rule adoption of TMDLs 

Broad stakeholder participation in developing a Basin Management Action Plan (B- 

MAP) (including detailed allocations and implementation strategies), incorporating it 

into existing management plans where feasible; public meetings during the planning 

process 

Emphasis on implementing the B-MAP, other voluntary stakeholder actions, and local 

watershed management structures; Department will continue to provide technical 

assistance, fulfill oversight responsibilities, and administer National Pollutant Discharge 

Elimination System point and nonpoint source permits 

The Watershed Management Cycle in 

the Florida Department of Environmental 

Protection’s Southwest District 

Figure 1.1 shows the order in which the Department’s Southwest 

District basins will be evaluated under the watershed management cycle. 

These groups are identified according to a U.S. Geological Survey classification 

system using hydrologic unit codes. 

Tampa Bay, a Group 1 basin, was the first basin in the district to 

undergo a preliminary assessment in 2000; an Assessment Report was published 

in 2002. It includes the bay and the major tributaries that contribute 

surface water flows to the bay. A preliminary assessment for the Group 2 

basin, Tampa Bay Tributaries, was completed in 2001, and an Assessment 

Report was published in 2004. This basin includes a second group of 

major tributaries to Tampa Bay: the Hillsborough, Alafia, Little Manatee, 

and Manatee Rivers. The boundaries of the Group 1 and 2 basins in the 

Department’s Southwest District are also encompassed by the boundaries of 

the Tampa Bay Estuary Program. 

The Group 3 basin, Sarasota Bay and Peace and Myakka Rivers, was 

assessed on a preliminary basis in 2002, and the basin is the subject of this 

Assessment Report. Similarly, a preliminary assessment for the Group 4 

basin, Withlacoochee River, was initiated in 2003, and the Group 5 preliminary 

assessment for the Springs Coast Basin began in 2004. In 2005, 

the cycle will resume with the Group 1 basin, Tampa Bay.

Chapter 2: Basin Overview 

Basin Setting 

Figure 2.1 shows the principal geopolitical features in the Sarasota Bay 

and Peace and Myakka Rivers Basin. 

Sarasota Bay 

The Sarasota Bay watershed lies primarily within Manatee, Sarasota, 

and Charlotte Counties. It contains some of Florida’s most beautiful and 

productive estuaries, including Sarasota Bay, Little Sarasota Bay, Dryman 

Bay, and Blackburn Bay. The watershed also contains numerous wetlands, 

small coastal streams that are tidally influenced over much of their length, 

a few longer stream/canal systems with predominantly freshwater habitats, 

such as Cow Pen Slough and Pearce Canal, and the barrier islands of Longboat 

Key, Lido Key, and Anna Maria Island. 

Sarasota Bay, the largest estuary in the watershed, extends from Anna 

Maria Sound and Palma Sola Bay, in the north, to Venice Inlet, in the 

south, a total of 52 square miles of open water. The contributing drainage 

area is approximately 150 square miles in size. 

The U.S. Environmental Protection Agency (EPA) designated the 

estuaries of Anna Maria Sound, Palma Sola Bay, Sarasota Bay, Roberts Bay, 

Little Sarasota Bay, and Blackburn Bay as an Estuary of National Significance 

in 1988, and established the Sarasota Bay National Estuary Program 

(SBNEP) in 1995. The Florida Department of Environmental Protection 

(Department) has also designated these estuaries as Outstanding Florida 

Waters (OFWs). In 1995, the Southwest Florida Water Management District 

(SWFWMD) placed Sarasota Bay on its Surface Water Improvement 

and Management (SWIM) Program list of priority waterbodies for protection 

or restoration. 

The region contains numerous resort communities and large populations 

of retirees, seasonal visitors, tourists, and other immigrants. About 

30 percent of the current population is over 65. Population growth around 

Sarasota, Dona, and Roberts Bays has been dramatic, especially after World 

War II. The population of both Manatee and Sarasota Counties was less 

than 150,000 in 1940. By 1995, that number had grown to about 514,000. 

Growth was especially rapid between 1980 and 1990, when the population 

of Manatee County grew nearly 43 percent, Sarasota County nearly 

37 percent, and Charlotte County 90 percent. The population is expected 

to grow considerably during the next 30 years, although more slowly than 

in the 1980s. 

Developed urban areas in the watershed include the mainland cities 

of Sarasota, Venice, and Bradenton, and the island communities of 

Longboat Key, Bradenton Beach, Holmes Beach, and Anna Maria. The 

Sources of 

Information 

Much of the information 

about the Sarasota Bay Basin 

in Chapters 2 and 3 was 

excerpted or adapted from 

the SWFWMD’s Southern 

Coastal Watershed Comprehensive 

Watershed Management 

Plan (November 2000).

developments nearest the coast tend to be older, with some newer development 

and redevelopment. Recently, eastward growth has occurred 

toward the Interstate 75 corridor. This trend will likely continue for the 

foreseeable future. 

Employment in Manatee, Sarasota, and Charlotte Counties is dominated 

by the service and retail industry sectors, which account for about 

60 percent of the region’s total jobs. The public sector constitutes the next 

largest employment category, accounting for 12 percent of the regional job 

base. Manufacturing also provides significant numbers of jobs, accounting 

for 14 percent of total employment in Manatee County. 

Land use/cover in the watershed is an amalgam of urban, agricultural, 

and wetland or open-water habitats. In 1995, urbanized areas accounted 

for over one-third of the total area (including open-water areas). Coastal 

areas, including the barrier islands, are almost entirely urbanized. Eastern 

portions of the watershed contain substantial areas of agricultural lands, 

which account for 10 percent of the total acreage. Agriculture is dominated 

by range and pastureland and row crop farming. Upland forests are patchily 

distributed, although a sizable intact, forested area remains inland from 

lower Sarasota Bay. 

Two major roads, U.S. Highway 41 and Interstate 75, roughly parallel 

the coast, providing north-south transit in the upper two-thirds of the 

watershed, and east-west transit around Charlotte Harbor to Punta Gorda 

in the lower third. Other major roads include State Road (S.R.) 64, which 

connects the city of Bradenton to Zolfo Springs in central Hardee County, 

and S.R. 70 and S.R. 72, which begin in Bradenton and Sarasota, respectively, 

and converge on the city of Arcadia in DeSoto County. A major 

rail line enters the watershed at Bradenton and runs south past the city of 

Venice. 

Peace River 

With a total surface area of 2,350 square miles, the Peace River watershed 

comprises SWFWMD’s largest drainage basin. Ninety percent of the 

watershed lies within Polk, Hardee, DeSoto, and Charlotte Counties, and 

smaller areas lie within Lee, Highlands, Manatee, Hillsborough, Glades, 

and Sarasota Counties. 

The headwaters of the Peace River include the majority of Polk, 

Hardee, and DeSoto Counties. The watershed begins in the Green Swamp, 

which was officially designated an Area of Critical State Concern in 1974 

because of its importance to the region’s water management and the threat 

of encroaching urbanization. The Peace River watershed contains some of 

the finest remaining examples of scrub habitat in the state, along with significant 

riverine floodplains, expanses of dry prairie, and a variety of other 

natural community types. In addition to providing habitat to numerous 

species of wildlife, these areas provide important ground water recharge, 

flood protection through the natural storage and detention of floodwaters, 

the maintenance and enhancement of water quality, and potable water 

supplies. Much of the river corridor itself has been spared the effects of 

development and continues to support natural stands of floodplain forest. 


Information 


about the Peace River 

watershed in Chapters 2 

and 3 was obtained from the 

SWFWMD’s Draft Peace River 

Comprehensive Watershed 

Management Plan (Vols. 1 

and 2, July 20, 1999).


About 55,000 acres of the watershed are currently in some form of 

conservation. The largest conservation area is the 67,426-acre Babcock/ 

Webb Wildlife Management Area in Charlotte County, about 35,000 acres 

of which lies in the watershed. Other, smaller areas include Tenoroc State 

Recreation Area in Polk County, R.V. Griffin Reserve in DeSoto County, 

Highlands Hammock State Park in Highlands County, and Lower Peace 

River Save Our Rivers (SOR) project in DeSoto County. 

The Peace River discharges to Charlotte Harbor, Florida’s second 

largest estuary. Mangroves and salt marshes line the shorelines in the 

lower reaches of the watershed, reflecting the estuarine conditions that 

occur here as the freshwater discharge of the Peace and Myakka Rivers 

mixes with the marine waters of the Gulf of Mexico. These estuarine 

communities, together with extensive seagrass meadows, make the watershed 

an extremely productive nursery for marine life. Most of the waters 

of Charlotte Harbor, which depends on freshwater flows from the Peace 

and Myakka Rivers, have been designated as aquatic preserves (Pine Island 

Sound, Matlacha Pass, Gasparilla Sound, and Cape Haze) in recognition of 

the outstanding natural values of the Charlotte Harbor Estuary. 

Major urban areas in the watershed include Lakeland, Auburndale, 

Haines City, Winter Haven, and Bartow to the north, as well as unincorporated 

Port Charlotte and Cape Coral at the southern end. Other 

population centers, situated along the middle reaches of the Peace River, 

include Fort Meade, Zolfo Springs, Bowling Green, and Arcadia. In 2000, 

the population of the watershed was about 366,000 people. By 2020, that 

number is projected to increase to approximately 480,000. 

Land use in the watershed is predominantly agricultural, mainly 

pasture and citrus cultivation. More detailed summaries of land use in the 

upper, middle, and lower portions of the Peace River watershed are provided 

in the nonpoint source sections of Chapter 3. 


Information 


about the Myakka River 

watershed in Chapters 2 and 

3 was excerpted from the 

SWFWMD’s Myakka River 

Comprehensive Watershed 

Management Plan (2000). 

Myakka River 

The Myakka River watershed extends over 550 square miles and 

includes lands in Manatee, Sarasota, and Charlotte Counties, as well as 

small portions of DeSoto and Hardee Counties. The Myakka River flows 

nearly 66 miles southwest from its headwaters in marshes near Myakka 

Head, until it discharges into the Charlotte Harbor Estuary. Just downstream 

of Myakka Head, 7 tributary creeks come together near Myakka 

City to form Flatford Swamp, a regionally important and unique surface 

water feature. Other important surface water features include the Tatum 

Sawgrass area, Upper Myakka Lake, and Lower Myakka Lake. 

The Myakka River watershed is ecologically valuable and significant 

due to the variety, quality, and diversity of its landscape. The watershed 

has more freshwater wetlands than any other area in Charlotte Harbor; it 

also includes extensive tidal wetlands. The central portion of the watershed 

features a large complex of public conservation lands, including Myakka 

River State Park, SWFWMD’s MacArthur Tract (Myakka Prairies), which 

is managed as part of Myakka River State Park, and Sarasota County’s 

Carlton Reserve. The Myakka River State Park, which covers 28,875 acres,


29 

includes a 12-mile reach of the Myakka River and a 7,500-acre wilderness 

preserve in the vicinity of Lower Myakka Lake. 

Much of the Myakka River has special protective designations. The 

34-mile segment of the Myakka River in Sarasota County has been designated 

a Wild and Scenic River by the state and, along with the downstream 

estuarine segment, is also designated as an OFW. 

Land uses in the Myakka River watershed are predominantly rural, 

with agriculture and conservation/recreation being the major land uses. 

Exceptions are the city of North Port—the only incorporated area in the 

watershed—and several “estate-type” residential subdivisions. The most 

urbanized portions of the watershed are south of U.S. Highway 41 in the 

North Port and Port Charlotte areas. Development pressure in the region 

is increasing as population growth fuels land conversions east of the cities 

of Sarasota and Bradenton, and the North Port/Port Charlotte area continues 

to develop. Most of the residents of Manatee, Sarasota, and Charlotte 

Counties live in a relatively narrow corridor roughly 10 miles inland from 

the Gulf, and most future growth is expected to occur in this corridor. 

As discussed earlier in this chapter, the region’s population grew very 

rapidly between 1980 and 1990. Manatee County’s population grew by 

about 43 percent, Sarasota County by about 37 percent, and Charlotte 

County by 90 percent. Statewide, growth averaged around 33 percent 

for the same period. By 1990, the population of the 5 counties (Manatee, 

Sarasota, Charlotte, Hardee, and DeSoto) and the city of North Port 

totaled about 827,000 people. By 2020, the population is estimated to 

grow to more than 1.1 million. These southwest Florida counties, especially 

the coastal areas, also experience significant seasonal population 

increases, ranging from 24 to 30 percent, between Thanksgiving and 

Easter. 

Most of the region’s growth can be attributed to the large number of 

retirees and others attracted to the mild climate and recreational opportunities 

in west-central Florida. Golf, fishing, and water-related activities are 

especially popular. Thirty percent of the population is over the age of 65. 

About 60 percent of the jobs in Manatee, Sarasota, and Charlotte 

Counties are in the service and retail industries. Manufacturing also 

plays a significant role in Manatee County. Tropicana Dole Beverages is 

Manatee County’s largest manufacturing employer, with about one-third 

of the employees in this sector. Agriculture and Port Manatee also provide 

significant numbers of jobs. Although agriculture is by far the largest 

single developed land use in the region, it is not as dominant as in the past, 

and its role continues to diminish as urban uses encroach into historical 

agricultural areas. 

Tourism plays a vital role in the economy of the west-central Florida 

region. Myakka River State Park provides many outdoor recreational 

opportunities, including hiking, camping, fishing, canoe rentals, and wildlife 

observation. The park, which is a favorite among bird-watchers due to 

its variety and quality of habitats, hosts nearly a quarter of a million visitors 

each year. 

The Charlotte Harbor estuarine complex is one of Florida’s least-spoiled 

systems and attracts visitors for recreational activities such as sportfishing,


boating, beach use, bird/wildlife observation, and scenic vistas. Sarasota 

and Charlotte Counties, the two counties in the Myakka watershed bordering 

the harbor, have more than 30,000 registered boats. Because of the 

Intracoastal Waterway, virtually every marina and boat ramp in the region 

has access to Charlotte Harbor and the Myakka River. 

Fishing is extremely popular in the Charlotte Harbor region, and the 

harbor is a significant nursery ground for marine and estuarine species. 

The main fishery species of commercial and recreational value include 

striped mullet, seatrout, red drum, black drum, king fishes, flounder, blue 

crabs, pink shrimp, stone crab, hard clams, snook, tarpon, grouper, snapper, 

Florida pompano, bluefish, sand seatrout, Spanish and king mackerel, 

sheepshead, and several species of sharks. Marine mammals commonly 

found in the area include the bottlenose dolphin and West Indian manatee. 

Surface Water Resources 

The Sarasota Bay and Peace and Myakka Rivers Basin contains 

numerous surface waterbodies. Surface waters, including lakes, streams, 

wetlands, and springs, occupy 815 square miles, or about 24 percent of the 

total basin area (Sarasota Bay, 216 square miles, or 26 percent; Myakka 

River, 143 square miles, or 18 percent; Peace River, 456 square miles, or 

56 percent). This section delineates the basin’s hydrology, describes the 

movement and management of water in the basin, briefly describes the 

major characteristics of surface waters that influence water quality in the 

basin, and describes surface water classifications and special designations. 

Figure 2.2 shows the locations of the largest waterbodies. A more 

detailed discussion in Chapter 3 provides information on each planning 

unit. 


The Sarasota Bay watershed supports a variety of wetland and upland 

ecosystems. It includes some of Florida’s most beautiful and productive 

estuaries, as well as numerous freshwater and saltwater wetlands, and 

several coastal streams and sloughs that are tidally influenced over much of 

their length. These streams and sloughs are typically intersected by drainage 

canals with predominantly freshwater habitats. 

In the northern portion of the watershed, a small area drains into 

Palma Sola Bay and several subbasins drain to the Sarasota Bay estuary. 

Freshwater runoff enters Sarasota Bay from the Bowlees Creek system, 

Whitaker Bayou, Hudson Bayou, other mainland coastal areas, and the 

barrier islands of Longboat Key, Lido Key, and Anna Maria Island. Portions 

of Anna Maria Island also drain to Anna Maria Sound. 

To the south, Phillippi Creek, a highly channelized drainage system, 

empties into Roberts Bay and Little Sarasota Bay. Catfish Creek and 

North Creek also drain into Little Sarasota Bay. Downshore, South Creek 

empties into a region known as Dryman Bay. Runoff from other coastal 

regions of the mainland, Siesta Key, and Casey Key also contributes to 

the freshwater flow entering Little Sarasota Bay. Farther south, Blackburn


31 

Figure 2.2: Surface Water Resources of the Sarasota Bay and Peace and Myakka Rivers Basin


Bay, Dona Bay, Roberts Bay (south), and Red Lake receive drainage from 

inland areas. 

Still farther south, Dona Bay and Roberts Bay (the second “Roberts 

Bay” in the watershed), which become contiguous at their western ends, 

are small estuaries near the city of Venice. Dona Bay receives some discharge 

from coastal regions, but most flow into the estuary is from Shakett 

Creek/Cow Pen Slough, a network of canals and natural stream segments 

that drains approximately 90 square miles. Cow Pen Slough’s watershed 

extends from southern Manatee County south and west to its outfall into 

Dona Bay in Sarasota County. The watershed is characterized by flat 

topography and undefined drainage ways, with primary drainage conveyed 

through approximately 14 miles of improved channel. 

Increased seasonal freshwater flow and sediment loads transported by 

this highly modified drainage system have contributed to the degradation 

of water quality and habitat in Dona Bay. Roberts Bay is the terminus for 

Curry Creek. Hatchett Creek is a highly channelized system that drains 

into the Intercoastal Waterway near the southern end of Roberts Bay. 

Blackburn Canal/Curry Creek provides a hydraulic connection between 

the Myakka River and Roberts Bay during periods of high flow. Up to 

10 percent of the Myakka River’s flows are diverted to Roberts Bay during 

high flow (Hammett, Turner, and Murphy, 1978). 


Surface water features in the Peace River watershed include streams, 

canals, numerous lakes, and springs. The headwater tributary streams of 

the Peace River occur in northern Polk County, with the river itself beginning 

at the junction of Saddle Creek and the Peace Creek Drainage Canal 

near Bartow. Large marshes or lakes form the headwaters of the river. 

The river system is rainfall driven, with little influence from ground water 

springs. 

The river flows generally southward for about 75 miles (through Polk, 

Hardee, DeSoto, and Charlotte Counties) and discharges into the northeastern 

portion of Charlotte Harbor near the town of Punta Gorda. Land 

surface elevations range from more than 200 feet above mean sea level near 

the headwaters to sea level at the river mouth. Upstream of Arcadia, the 

channel of the Peace River is generally well defined. Below Arcadia, however, 

the channel becomes braided and the width of the floodplain increases 

substantially, exceeding a mile in some places. During periods of low river 

flow, the system is tidally influenced from Fort Ogden to the mouth. 

Tidal flooding occurs along the coast and in the lower reaches of the 

Peace River. Additionally, numerous bridges cross the river; these become 

potential dams if vegetation jams on pilings impede or halt water flow. 

Localized upstream flooding can result, as well as damage to the bridges. 

The river is free flowing over its entire reach. Two tributaries have 

regulated flows, including a control structure (P-11) on Saddle Creek south 

of Lake Hancock and a dam at the city of Punta Gorda’s water supply 

reservoir on Shell Creek. Water withdrawals are made at the Peace River/ 

Manasota Regional Water Supply Authority water plant south of Arcadia.


33 

The major surface water features in the watershed include the Peace 

River and its tributaries and a large number of lakes, most of which are 

found in Polk County. These include Lakes Gibson, Cargo, Parker, 

Hancock, Lena Run, Smart, Rochelle, Haines, Maude, Buckeye, Connie, 

Crystal, Eloise, Shipp, May, Howard, Cannon, Hartridge, Idylwild, Jessie, 

Blue, Elbert, and Banana, as well as Hollingworth Lake, Lulu Outlet, 

Fannie Outlet, and others. Many of these lakes drain to the Peace River 

system via tributaries to Saddle Creek (Lakes Hancock, Parker, and 

Banana) or the Peace Creek Canal (Winter Haven Chain of Lakes). Except 

for Lake Parker, which is used for recirculating power plant cooling water, 

withdrawals from these lakes are for small agricultural or private uses. 

Lake Hancock, a large, hypereutrophic lake, contributes an average of 

52 cubic feet per second (cfs) to the Upper Peace River. A water control 

structure on Lake Hancock was constructed in the early 1960s, and flows 

from the lake have been regulated ever since. Outflows from the lake currently 

degrade water quality in the Peace River. 

The Peace Creek Canal was excavated in the early 1900s to drain lowlying 

lands in Polk County south of the Winter Haven Chain of Lakes. 

Frequent flooding still occurs in low areas near the canal, with large areas 

of standing water present for several months during some years. Part of this 

problem is unavoidable due to the flat topography of the canal basin. Water 

control structures on Lakes Lulu and Hamilton affect flows to the Peace 

Creek Canal and the Upper Peace River. 

Significant declines in stream flow have been documented in the main 

stem of the Peace River, with the greatest rates of decline observed in the 

upper reaches of the river near Bartow and Zolfo Springs. Kissengen 

Springs, which contributed approximately 20 million gallons per day (mgd) 

to the Upper Peace River, stopped flowing during the early 1950s. Sinks 

and small springs are located in the channel and floodplain of the Upper 

Peace River. During much of the dry season, the river loses flow to the 

sinks and springs between Bartow and Fort Meade. 

Reduced rainfall and drawdowns of the Floridan aquifer in the Upper 

Peace River watershed from human uses have been identified as major 

factors for the decreased flows. While ground water levels in much of the 

watershed have increased due to reduced ground water pumping, flows in 

the upper river have not substantially recovered because of reduced rainfall. 

Early phosphate mining in the Upper Peace River watershed altered 

surface drainage patterns and the surface water/ground water relationships 

of the river and its tributaries. Although most of the mining has occurred 

since the 1940s, phosphate pebble was mined from the channel of the Peace 

River during the late 1800s. Many lands were mined before the state first 

required land reclamation in 1975. Current reclamation efforts attempt 

to mimic the premining hydrology. Because reclamation philosophies and 

techniques have evolved considerably during the last two decades, the basin 

now contains a complex mosaic of reclaimed lands with different hydrologic 

characteristics.



Surface waters in the Myakka River watershed include numerous freshwater 

and saltwater wetlands and several stream and slough systems. 

The Myakka River is 1 of the 3 tributaries to Charlotte Harbor. The 

other 2 tributaries are the Peace and Caloosahatchee Rivers. The headwaters 

of the Myakka River are in eastern Manatee County near Myakka 

Head. From there, the river flows approximately 66 miles in a southerly 

direction through Manatee, Sarasota, and Charlotte Counties, where it 

empties into northwestern Charlotte Harbor. The river is the second largest 

source of freshwater inflow for Charlotte Harbor, which is 1 of the most 

productive estuaries in southwest Florida. 

Major surface waters in the basin include Flatford Swamp, Ogleby 

Creek, Owen Creek, Tatum Sawgrass Area, Upper and Lower Myakka 

Lakes, Deer Prairie Creek, and Myakkahatchee Creek/Big Slough Canal. 

Two surface water features unique to the area are Warm Mineral Springs 

and Little Salt Spring in North Port; these are the southernmost springs in 

the SWFWMD. 

In its upper reaches near Myakka Head, the river consists of a very 

narrow channel resembling a small creek. The differences between dry 

season and wet season flows are extreme, with 73 percent of the river’s flow 

occurring from July through October. During the dry season, particularly 

in April and May, the upper reaches of the river are often completely dry. 

The Myakka River has an average flow of 251 cfs at the Sarasota gage and a 

maximum recorded flow of 8,670 cfs for the period of record. 

The tidal influence of the Gulf of Mexico extends more than 25 miles 

up the Myakka River to a water control structure in the river channel, 

downstream from Lower Myakka Lake (Down’s Dam). 

Topographic relief in the watershed varies from sea level to elevations 

of greater than 100 feet above sea level at the river’s source near Myakka 

Head. Where the Myakka River and Charlotte Harbor merge, the topography 

is generally flat to gently sloping, with elevations varying from about 

25 feet above sea level at the highest, to sea level at the Myakka River 

mouth and Charlotte Harbor. The Myakka River floodplain varies in 

width from less than 1 mile in the upper basin to more than 3 miles in the 

lower basin. 

The upland areas drained by the Myakka River are characterized by 

a high water table and poor drainage due to underlying organic hardpan 

soils. Intermittently wet ponds dot the landscape. Water flow in 

the Myakka River comes primarily from runoff. There is little evidence 

of artesian contributions to the river. The tributaries and sloughs of the 

watershed’s large streams are usually only a few feet deep. 

Surface Water Quality Classifications 

Florida’s water quality standards, the foundation of the state’s program 

of water quality management, designate the “present and future most 

beneficial uses” of the waters of the state (Subsection 403.061[10], Florida 

Statutes [F.S.]). Water quality criteria for surface water and ground water,


35 

expressed as numeric or narrative limits for specific parameters, describe the 

water quality necessary to maintain these uses. Florida’s surface water is 

classified using the following five designated use categories: 

Class I 

Class II 

Class III 

Class IV 

Class V 

Potable water supplies 

Shellfish propagation or harvesting 

Recreation, propagation, and maintenance of a healthy, 

well-balanced population of fish and wildlife 

Agricultural water supplies 

Navigation, utility, and industrial use (there are no state 

waters currently in this class) 


All of the coastal tributaries to Sarasota Bay are designated as Class III 

waterbodies (marine and fresh water). Palma Sola Bay and one segment of 

Sarasota Bay are designated as shellfish propagation and harvesting areas 

(Class II). There are no Class IV or V waters present in the watershed. 


Most reaches of the Peace River and its tributaries are designated as 

Class III waterbodies. The exceptions include Shell Creek, Prairie Creek, 

portions of the Port Charlotte Canal System, and the southernmost portion 

of Horse Creek (downstream of S.R. 761), which are Class I waters. 

The lowermost reach of the river, extending from the Barron Collier (U.S. 

Highway 41) Bridge to the river mouth, falls within the Charlotte Harbor 

Aquatic Preserve and is designated as a shellfish propagation and harvesting 

area (Class II). There are no Class IV or V waters present in the watershed. 

The majority of the Peace River is Class III waters. However, three 

tributaries discharging to the lower portion of the river include Class I 

waters requiring a greater degree of protection. These tributaries include 

the lower portion of Horse Creek from the northern border of Section 14, 

T38S, R23E, southward to the Peace River, as well as the headwaters of 

Prairie Creek to the Charlotte County line and the headwaters of Shell 

Creek to the Hendrickson Dam. These tributaries (or portions of them) 

serve as potable water supply sources for the cities of Punta Gorda and 

North Port, and several surrounding counties (Charlotte, Sarasota, and 

DeSoto). 


Most reaches of the Myakka River and its tributaries are designated as 

Class III waterbodies. Exceptions include the river reach that extends south 

from the Manatee County line through Upper and Lower Myakka Lakes to 

Manhattan Farms (north line of Section 6, T39S, R20E) and Big Slough 

Canal (headwaters to U.S. Highway 41). Both of these are Class I waters. 

Big Slough Canal/Myakkahatchee Creek is a potable water source for the 

city of North Port. 

The southernmost reaches of the river, extending south from the western 

line of Section 35, T39S, R20E in Sarasota County and all of the river


in Charlotte County are designated as a shellfish propagation and harvesting 

area (Class II). There are no Class IV or V waters in the watershed. 

Special Designations 

Outstanding Florida Waters 

OFWs are designated for “special protection due to their natural 

attributes” (Section 403.061, F.S.). These waters are listed in Section 62- 

302.700, Florida Administrative Code (F.A.C.). The intent of an OFW 

designation is to maintain ambient water quality, even if these designations 

are more protective than those required under the waterbody’s surface 

water classification. Most OFWs are associated with managed areas in the 

state or federal park system, such as aquatic preserves, national seashores, or 

wildlife refuges. Other OFWs may also be designated as “Special Waters” 

based on a finding that the waters are of exceptional recreational or ecological 

significance, and are identified as such in Rule 62-302, F.A.C. 

The following waterbodies in the Sarasota Bay and Peace and Myakka 

Rivers Basin have been given additional protection through designation as 

OFWs: 

Sarasota Bay. The Sarasota Bay estuarine system, consisting of the 

estuaries of Anna Maria Sound, Palma Sola Bay, Sarasota Bay, Roberts Bay 

and Little Sarasota Bay, is designated as an OFW. 

Peace River. The estuarine portion of the Peace River (downstream 

of U.S. Highway 41) is designated as an OFW due to its location in the 

Charlotte Harbor Aquatic Preserve. 

Myakka River. The entire portion of the Myakka River that flows 

through Sarasota County and the estuarine portions of the river are designated 

as an OFW because they lie, respectively, in a segment designated 

as a Wild and Scenic River and the Gasparilla Sound–Charlotte Harbor 

Aquatic Preserve. 

Surface Water Improvement and Management Priority Waters 

In 1987, the Florida legislature created the SWIM Program to restore 

waterbodies. The initial legislation identified 6 priority waterbodies: Lake 

Apopka, Tampa Bay, Indian River Lagoon, Biscayne Bay, Lower St. Johns 

River, and Lake Okeechobee. Today, SWIM plans have been developed 

for 30 waterbodies statewide. The SWIM Program addresses a waterbody’s 

needs as a system of connected resources, rather than isolated wetlands or 

waterbodies. The state’s 5 water management districts work with federal, 

state, and local governments and the private sector to develop and implement 

SWIM plans to restore damaged ecosystems, prevent pollution from 

runoff and other sources, and educate the public. 

The following waterbodies in the Sarasota Bay and Peace and Myakka 

Rivers Basin are SWIM priority waters for restoration. 

Sarasota Bay. In 1995, Sarasota Bay was designated as a SWIM priority 

waterbody, and the Sarasota Bay SWIM Plan was approved in 1997. 

Peace River. The Winter Haven Chain of Lakes, a system of 19 interconnected 

lakes with a combined surface area of 7,000 acres in and around 

the city of Winter Haven in north-central Polk County, is a SWIM priority


37 

waterbody. An updated SWIM Plan for the Chain of Lakes was published 

in 1998. 

Myakka River. SWFWMD staff, working with the Charlotte Harbor 

SWIM Advisory Committee, recently updated the SWIM Plan for the 

estuary and its drainage basin (including the Myakka watershed), which 

was approved in 2000. 

Minimum Flows and Levels 

Under the Florida Water Resources Act (Chapter 373, F.S.), a minimum 

flow and level (MFL) is the limit at which further water withdrawals 

will cause significant harm to the water resources of the area and related 

natural systems. Consumptive use and alterations to these watersheds have 

reduced or have the potential to reduce the amount and timing of surface 

water being delivered. Projected increases in withdrawals also could reduce 

future flows and levels. 

To help determine the amount of water that is available for human use 

from a particular source, the SWFWMD must determine each waterbody’s 

MFL. Lakes and aquifers have minimum levels. Minimum flows are set 

for rivers and streams. Table 2.1 contains SWFWMD’s 2003 priority list 

and schedule for the establishment of MFLs in the Sarasota Bay and Peace 

and Myakka Rivers Basin.

Ground Water Resources 

Aquifers 


The Sarasota Bay watershed lies in the Southern Coastal Watershed, 

which is located in the Southern West-Central Florida Ground Water Basin 

(SWCFGWB), one of three distinct ground water basins in west-central 

Florida. No significant ground water flow crosses the basin boundaries; 

therefore, nearly all ground water is derived from recharge by rainfall in the 

basin. Upper Floridan aquifer flow in the SWCFGWB derives primarily 

from rainfall recharge in the Lake Wales Ridge area and the Green Swamp, 

which are located along the northern and eastern edges of the basin, respectively. 

Downgradient of these areas, ground water flows west and southwest 

toward and into the Gulf of Mexico, except in southern Hillsborough 

and western Manatee Counties, where flows are limited due to ground 

water pumpage. 

Within the SWCFGWB, the ground water system is divided into three 

main aquifers: the surficial, intermediate, and upper Floridan. A confining 

layer of variable thickness and areal extent separates each aquifer. The 

uppermost aquifer, the surficial, is largely undeveloped due to its limited 

thickness and low permeability, except near the coast and in Charlotte 

County, where ground water from deeper aquifers is too mineralized for 

potable use. Underlying the surficial aquifer is the intermediate or secondary 

artesian aquifer system. The intermediate aquifer system is a moderately 

productive, highly developed source of water that is used for domestic 

and public supplies south of Polk County. 

The lowermost and most productive aquifer is the upper Floridan aquifer 

system, the primary artesian aquifer throughout Florida and much of 

the southeastern United States. The Floridan aquifer consists of two transmissive 

zones, the upper and lower Floridan aquifers, which are separated 

by the middle confining unit. This aquifer consists of a thick sequence 

of sedimentary rocks of Eocene to Miocene age. These limestone units 

comprise the Tampa, Suwannee, Ocala, and Avon Park Formations. The 

Avon Park formation is the deepest containing potable water. Generally, 

water quality in the upper Floridan is good, but it tends to deteriorate due 

to increasing mineralization as one moves south into the Everglades region. 


Aquifers underlying the watershed include the unconfined surficial 

aquifer, 2 artesian intermediate aquifers (the Tamiami–upper Hawthorn 

and lower Hawthorn–upper Tampa) and their confining units, and the 

artesian Floridan aquifer and its confining units. The Floridan aquifer is a 

thick layer (200 to 1,200 feet) of water-bearing limestone and dolomite of 

Eocene to Miocene age. 

The intermediate aquifers consist of an upper (Tamiami–upper 

Hawthorn) unit containing phosphatic marl, shell, sand, clayey sand, and 

phosphatic limestone of mid-Miocene to Pliocene age, and a lower (lower 

Hawthorn–upper Tampa) unit made up of permeable limestone and


39 

dolomite of lower and mid-Miocene age. The thickness of the upper unit 

ranges from 200 to 400 feet, and of the lower unit from 150 to 300 feet. 

A confining bed of relatively impermeable, clayey material separates the 

2 aquifers. Numerous breaches in the confining bed, however, appear to 

provide hydraulic connections between the 2 systems. 

The lower Hawthorn–upper Tampa aquifer is recharged by lateral 

flows and upward leakage from the Floridan aquifer, and discharges to the 

Tamiami–upper Hawthorn aquifer. In some portions of the watershed, the 

Tamiami–upper Hawthorn aquifer is also recharged by downward leakage 

from the surficial aquifer. Historically, however, the potentiometric surface 

of the Tamiami–upper Hawthorn aquifer has been higher than the surficial 

water table in many areas, and the aquifer has discharged to the surficial 

system (of wetlands, lakes, and streams) in those areas. 

The surficial aquifer is made up of undifferentiated surface deposits 

(e.g., quartz sand, marl, shell, and peat) and two named stratigraphic 

units (Caloosahatchee marl and the Bone Valley formation) that range 

from Pliocene to Holocene age. Historically, the surficial aquifer has been 

recharged by rainfall, upward leakage from the Tamiami–upper Hawthorne 

aquifer, the infiltration of irrigation water, and lateral ground water 

flows from adjacent areas. 

The direction of regional ground water flow in the watershed is generally 

west/southwest, from the Green Swamp potentiometric high in the 

northeast part of the basin to the Gulf of Mexico. Ground water in the 

upper Floridan aquifer originates as rainfall over the watershed that percolates 

to the water table in the surficial aquifer. It then moves vertically 

downward across a confining unit into the intermediate aquifer and across a 

second confining unit into the upper Floridan aquifer. 

Northern portions of the watershed contain abundant phosphate 

deposits in the surficial and intermediate aquifer systems. In addition to 

phosphate, those deposits are relatively rich in radionuclides of the uranium-238 

series (including radium-226 and radon-222). Mining and 

processing of phosphate deposits have taken place in the Upper Peace River 

watershed since the late 1800s. Elevated concentrations of phosphate 

occur in surface water and ground water in the area, due to a combination 

of natural processes and human activities associated with the mining and 

processing of phosphate ore. 

Abundant sinkholes and former springs indicate the presence of connections 

between the surficial aquifer and deeper water-bearing units in the 

watershed. Historically, the northern portion of the Peace River watershed 

appears to have been an area of widespread upward leakage and artesian 

flow from the intermediate Hawthorn system. In recent decades, however, 

a combination of decreased rainfall and increased human use has reduced 

the potentiometric surfaces of the lower aquifers. This appears to have 

reversed the historical hydrologic condition in portions of the northern 

watershed, such that the prevailing direction of flow is now downward from 

the Peace River system to the intermediate and Floridan aquifers in much 

of the area.



Like the Sarasota Bay watershed, the Myakka River watershed lies in 

the SWCFGWB, one of three distinct ground water basins in west-central 

Florida. No significant ground water flow crosses the watershed’s boundaries; 

hence, all ground water in the watershed is derived from recharge by 

rainfall. 

Within the SWCFGWB, the ground water system is divided into 

3 main aquifers: the surficial, intermediate, and Floridan. Each aquifer is 

separated by a confining layer of variable thickness and areal extent. The 

uppermost aquifer, the surficial, is largely undeveloped due to its small 

thickness and low permeability, except near the coast and in Charlotte 

County, where ground water from deeper aquifers is too mineralized for 

potable use. The surficial aquifer occurs in the undifferentiated sands that 

overlie the basin and generally varies from less than 25 feet in the southern 

areas to more than 50 feet in thickness in the northeastern areas of the 

Manatee County. These sands yield limited quantities of water, primarily 

used for lawn irrigation. 

Underlying the surficial aquifer is the intermediate or secondary 

artesian aquifer system, which occurs in the Hawthorn Formation. The 

intermediate aquifer system is a moderately prolific, but highly developed, 

source of water and is widely used for domestic and public supplies south of 

Polk County. 

The intermediate aquifer in the SWCFGWB averages 700 feet in 

thickness in southern Charlotte County, but thins toward the north. 

Within the Myakka River watershed, the intermediate aquifer varies in 

thickness from less than 200 feet to more than 350 feet. Lenses of pure 

limestone, clay, and sand exist throughout the formation, and domestic 

water well production occurs from the porous limestone layers. 

The lowermost aquifer in the watershed, the Floridan aquifer system, 

thickens from approximately 1,200 feet in the northern areas of the watershed 

to more than 1,800 feet to the south. The upper Floridan is the major 

source of water for agriculture, industry, and public supply in the watershed, 

except in southern DeSoto and Charlotte Counties and the coastal 

areas of Manatee and Sarasota Counties, where water quality is relatively 

poor. 

The Myakka watershed provides little recharge to the Floridan aquifer, 

which is generally recharged along the sand ridges in the eastern part of 

the SWFWMD. In this ridge area, the surficial aquifer is quite permeable, 

the intermediate aquifer is mostly absent, and the confining layers and 

clays between the surficial and Floridan aquifers are thin to absent. Upper 

Floridan aquifer flow in the SWCFGWB derives primarily from rainfall 

recharge in the Green Swamp and Lake Wales Ridge areas, along the 

northern and eastern edges of the watershed, respectively. Downgradient 

of these areas, ground water flows west and southwest toward and into the 

Gulf of Mexico.


41 

Ground Water–Surface Water Interactions 

Ground water and surface interactions in the Sarasota Bay and Peace 

and Myakka Rivers Basin area are localized and very complex. There are 

three aquifer systems that consist of thick sequences of carbonate rocks, 

discontinuous clays, and clastic sediments. Ground water flow patterns are 

very intricate due to differences in gradients and pressure both within and 

between the hydrologic units. 

Three distinct physiographic regions coincide with changing discharge 

and recharge patterns of the upper Floridan aquifer. Generally, the Polk 

Upland is an area of ground water recharge and karst geology, the DeSoto 

Plain can have reversals of both recharge and discharge, and the Gulf 

Coastal Lowlands have ground water discharge from the Floridan aquifer. 

Both ground water discharge and recharge rates are generally low throughout 

the basin and average less than an inch per year. 

Increasing ground water withdrawals have considerably altered the 

potentiometric surface of the upper Floridan. Extensive water demands 

in an area of slow ground water flow rates, low recharge rates, and thick 

confining beds have lowered the potentiometric surface more than 60 feet 

over the long term. 

The intermediate aquifer contains 3 separate zones that are generally 

interconnected and have a changing downward or upward hydraulic gradient. 

Specific areas where the intermediate aquifer is either not confined 

or has a breach in the confining unit will have ground water flow to the 

surficial aquifer and/or surface water. One example, the upper Tamiami 

Formation in Sarasota County, is an artesian zone that is less than 80 feet 

thick but not continuous. 

The hydraulic properties of the surficial aquifer are also extremely 

variable and can either enhance or retard the exchange of water between 

surface waterbodies and ground water. Discontinuous layers of clay stringers 

that underlie the surficial aquifer can restrict vertical ground water flow, 

resulting in increased sheet flow or runoff. 

Very few springs are present in the basin because of the high degree of 

confinement of the aquifer systems. The natural ground water inputs in 

the Myakka watershed are negligible, except in the dry season when there 

is minimal precipitation. The largest springs, Little Salt Springs and Warm 

Mineral Springs, are near the Myakka River and in Sarasota County. 

Springs that historically existed in the basin may not be flowing today. For 

example, Pinehurst Spring near Sarasota was capped by Pinehurst Bottling 

Company in 1946 for private sales. 

Along the middle portion of the Peace River, small, unnamed springs 

have been observed along the streambed. However, a long-term decline 

in stream flow in the Peace River has occurred since 1931 due to reduced 

rainfall and increased ground water withdrawals for human uses. The control 

structures at Lake Hancock and the Peace Creek Drainage Canal also 

limit the release of surface water to the river during the dry season. The 

decline in rainfall has resulted in reduced aquifer levels and the cessation of 

flow at several springs near and within the Peace River channel, including 

Kissingen Spring (previous average flow 19 mgd). Stream flow now enters


sinkholes in the streambed and floodplain during periods when aquifer 

levels are low. 

Ground water issues related to natural processes in the basin are controlled 

by differences in and the dissolution of aquifer minerals, saltwater 

mixing, and upward leakage from the upper Floridan aquifer. The issues of 

greatest regional importance to ground water quality are saltwater intrusion 

from coastal areas or remnant seawater and nutrient enrichment. Salt water 

reaches ground water through natural processes or anthropogenic activities. 

Saltwater intrusion is occurring where water supply wells are located 

near coastal areas and increased pumping moves the freshwater/saltwater 

interface landward. Excessive pumping has also caused an upward flow of 

poorer quality water from the deeper mineralized Floridan aquifer into the 

intermediate aquifer system. 

Ground water in the upper Floridan is part of a freshwater regional 

flow system that travels from the northeast and toward the coast, where it 

discharges offshore. However, pumping has interfered with these flows by 

inducing a more vertical gradient and allowing the upwelling of mineralized 

ground water from the lower Floridan aquifer. This results in shorter 

upward flow paths, so that the Floridan ground water discharges to the 

intermediate aquifer, rather than continuing its regional and lateral movement 

toward the coast. Modeling has shown an estimated 50 percent 

reduction in ground water discharge beneath the Gulf of Mexico. 

Ground Water Usage 

The following describes ground water use in the Sarasota Bay and 

Peace and Myakka Rivers Basin, including the principal sources for withdrawals, 

timing of water usage, and other issues. 


Public supply represents the most significant water use in the Sarasota 

Bay watershed. Each community in the watershed meets potable water 

demands through ground water or surface water resources. The watershed 

has 9 public supply well fields/withdrawal sites with average permitted 

quantities greater than 1 mgd, as well as 14 public supply water facilities 

that withdraw more than 100,000 gallons per day. 

Agriculture has historically been a significant activity in the watershed 

and continues to play a significant role in water supply demands. As 

development pressures continue to consume increasingly valuable coastal 

agricultural lands, water demands from agricultural activities in the watershed 

are likely to decrease. Continued urbanization of the watershed may, 

however, lead to expanded agricultural and/or ranching operations farther 

inland, increasing water demands in those watersheds. 

Recreational water use in the watershed is also significant. Most withdrawals 

in this category are used to meet golf course irrigation demands. 

In recent years, many golf courses have sought to offset all or a portion of 

their potable water use with reclaimed wastewater reuse, which has proven 

to be a significant water conservation measure that reduces ground water 

and surface water withdrawals. However, utilities must develop additional 

wet weather storage to make reuse available year round.


43 

Significant surface water, public supply sources play an important 

role in meeting potable water demands in the watershed. These sources 

include Lake Manatee and the Evers Reservoir, which are impoundments 

of the Manatee and Braden Rivers, respectively, in Manatee County. The 

Peace River/Manasota Regional Water Supply Authority’s (PRMRWSA’s) 

water treatment facility is located on the Peace River in DeSoto County. 

Lake Manatee serves as a potable water supply source for Manatee County 

Utilities, while the Evers Reservoir provides potable water resources to the 

city of Bradenton. While none of these facilities is in the watershed, each 

facility supplies significant quantities of potable water to its communities. 

Lake Manatee is permitted for average and maximum daily withdrawal 

quantities of 34.9 mgd and 50.2 mgd, respectively. The Evers Reservoir 

is permitted for average and maximum daily withdrawals of 5.6 mgd and 

8.2 mgd, respectively. The PRMRWSA facility is permitted to withdraw 

up to 17.6 mgd. 

Potentiometric levels of the upper Floridan aquifer, the principal aquifer 

in the SWFWMD’s jurisdiction, have been declining in the coastal areas of 

southern Hillsborough, Manatee, and northern Sarasota Counties since the 

1930s. The rate of these declines greatly accelerated beginning in the early 

1960s, and declines are now observed throughout the entire SWCFGWB, 

which includes all of DeSoto, Hardee, Manatee, and Sarasota Counties, 

and portions of Charlotte, Highlands, Hillsborough, and Polk Counties. 

The declines are primarily caused by ground water withdrawals. The 

regional impacts of these lowered levels include water quality deterioration 

in coastal areas due to lateral saltwater intrusion, and local water quality 

deterioration due to the upward movement of mineralized water from lower 

portions of the aquifer. Additional impacts include reduced well efficiency 

due to greater pumping depths, lowered lake levels, and reduced spring and 

stream flows. As a result of these declines, the SWFWMD plans to establish 

minimum aquifer levels for the intermediate aquifer by 2011. 

Many ground water withdrawals in the watershed are from brackish 

sources. Brackish water is generally defined as water with a total dissolved 

solids concentration greater than 1,000 parts per million. It can be 

made potable by various membrane technologies. While these methods 

have historically been expensive, recent improvements in technology have 

reduced operating costs for newer systems. Currently, the cities of Sarasota 

and Venice supplement their water supplies using membrane treatment 

technology. 

One of the more significant problems facing the desalination industry, 

however, is the disposal of waste brine, which is classified as industrial 

waste. The Department regulates the treatment and disposal of industrial 

wastewater through Rules 62-3, 62-4, 62-6, and 62-8, F.A.C. Since most 

plants are near the coast, discharge to tidal or brackish surface waters is one 

method of disposal. Locating disposal sites with adequate dilution, flushing, 

and marine characteristics can, however, be problematic. Other methods 

of disposal include percolation ponds, spray irrigation, or deep-well 

injection. Given the continued growth in Florida’s coastal areas, unpredictable 

rainfall, and increasing saltwater intrusion, the use of membrane 

technology for potable water supply development is anticipated to increase.



The principal source of water supply in the Peace River watershed is 

ground water from the upper Floridan aquifer. The major use of water in 

the watershed has historically been for agricultural irrigation, public supply, 

and mining and processing phosphate ore. The SWFWMD estimates that 

in 1996 about 298 mgd were used throughout the watershed. Approximately 

92 percent (274 mgd) of this was obtained from ground water 

sources, and 8 percent (24 mgd) came from surface water sources. The 

largest water use in 1996 was for agricultural irrigation (194.7 mgd, or 

65 percent), and the second largest use was for public supply (53.8 mgd, or 

18 percent). The combined water use for mining/dewatering and industrial/commercial 

users was 40.8 mgd, or 14 percent of total water use. 

In the southern portions of the watershed, the Floridan aquifer is 

highly mineralized, and the surficial and intermediate Hawthorn aquifers 

are the major sources of ground water supply. As a result, the Lower 

Peace River is projected to serve as an important source of water to meet 

increased demand for domestic water supply in the southern part of the 

SWFWMD. 

Surface water supplies taken directly from the Peace River and its 

tributaries are currently restricted to 3 small agricultural withdrawals and 

2 separate municipal water supplies obtained from the Lower Peace River 

and Shell Creek. Withdrawals from the Lower Peace River are permitted 

to the PRMRWSA, which has been in service since 1980. Recent withdrawals 

have averaged about 10 mgd. Over the next 20 years, the facility 

will be expanded to serve as a regional water supply source, eventually 

providing an average of 32.6 mgd to residents of Charlotte, Sarasota, and 

DeSoto Counties. 

The city of Punta Gorda has used Shell Creek for potable water supplies 

since the 1940s. Water use from the creek has averaged about 5 mgd 

in recent years. Withdrawals are taken from an instream impoundment in 

the tidal portion of the creek about 6 miles upstream from the confluence 

with the Lower Peace River. 


The water resources in the Myakka River watershed provide water 

supply for agriculture, public supply, industry, and recreation. Permitted 

withdrawals are 110.7 mgd from traditional sources (surface water and 

ground water). The largest permitted withdrawals, for agriculture, are 

pumped almost entirely from ground water sources. Public supply is the 

second permitted use, while other withdrawals make up only a few percentage 

points of demand. 

The upper Floridan aquifer is the principal source of ground water in 

the watershed. Under natural conditions, the aquifer is well confined and 

has poor hydraulic connections to surface water systems. Natural recharge 

to the upper Floridan in the watershed is almost nonexistent. The principal 

recharge area for the aquifer in this region is in Highlands and Polk Counties 

to the east and northeast. 

Because of poor water quality in the upper Floridan, the intermediate 

aquifer system is an important but less productive source of water. The


45 

intermediate aquifer also functions as a major confining unit between the 

upper Floridan and the surficial aquifer system near the land surface. Most 

surface water and ground water interaction in the watershed occurs principally 

between the surface waterbodies (lakes and rivers) and the intermediate 

and surficial aquifers. 

Water quality is the principal constraint on the watershed’s ground 

water supply. In Sarasota and Charlotte Counties, the total dissolved 

solids for raw upper Floridan aquifer water are above 500 milligrams per 

liter (mg/L), and water quality deteriorates from north to south. Such 

poor-quality water requires extraordinary treatment for public supply water 

use. Water quality in the surficial and intermediate aquifers is generally of 

acceptable quality but degrades in the coastal areas and with depth in the 

intermediate aquifer. 

As of 1996, surface water provided only 7.3 percent of the water 

demand in the watershed. Much of that water is derived from shell pits 

and canals. There are no direct withdrawals from the Myakka River. The 

only significant surface water withdrawal is from Myakkahatchee Creek 

(Big Slough Canal), a Myakka River tributary that passes through the 

city of North Port. The city is permitted to withdraw an annual average 

of 2.08 mgd. A salinity dam, installed on the creek in the 1970s, protects 

water quality from tidal seawater, but there is no reservoir. 

Permitted water use for 1998 in the basin was 98.5 mgd from ground 

water sources and 12.2 mgd from surface water sources. The largest permitted 

use was 92.6 mgd for agriculture. Public supply, the second largest 

permitted use, was permitted to withdraw 13.8 mgd, mostly from ground 

water. Other uses were permitted for very small quantities. 

In 1998, 25.3 mgd were withdrawn for agriculture. Typically, the 

largest agricultural irrigation withdrawals in the watershed are for tomatoes, 

vegetables, and citrus. Agricultural withdrawals are almost entirely 

from ground water and are highly concentrated on a seasonal basis. These 

seasonal withdrawals produce a significant decline in the potentiometric 

surface of the upper Floridan aquifer, especially during the spring dry 

season. In 1989, the decline was so great that a portion of the potentiometric 

surface in the watershed was below sea level. Most of the 7.16 mgd 

of surface water withdrawals were by one permitted user who uses ponds 

and canals for irrigation water. 

After agriculture and public supply use, all other 1998 withdrawals 

totaled only 1.8 mgd, principally for golf courses and some sand 

mining. Most sand mining processes recirculate their water and have little 

consumptive use. 

Water Use Caution Areas 

Under Section 373.036, F.S., and Subsection 62-40.520(1), F.A.C., 

each water management district in the state must identify Water Use 

Caution Areas (WUCAs) in which potential water shortages, considerable 

reductions in water levels, saltwater intrusion, or other degradations may 

occur within 20 years, and must develop management plans to address 

their water resource problems. In these areas, existing and anticipated 

sources of water and conservation efforts may not be adequate to supply


water for all existing legal uses and reasonably anticipate future needs, and 

still sustain water resources and related natural systems. Five constraints 

are considered in establishing these WUCAs: 

• Impacts to native vegetation, primarily wetlands; 

• Impacts to minimum flows and levels, primarily spring flows; 

• Impacts to ground water quality in terms of increased saltwater 

intrusion; 

• Impacts to existing legal users; and 

• Failure to identify a source of supply for future development. 

The SWFWMD has designated the following areas in the Sarasota Bay 

and Peace and Myakka Rivers Basin as WUCAs. 


The watershed is located within 2 WUCAs: Southern (SWUCA) and 

Eastern Tampa Bay. The SWFWMD established the SWUCA in 1992 in 

response to regional declines in the aquifer’s potentiometric surface. The 

SWUCA, which encompasses about 5,100 square miles, comprises all of 

Manatee, Sarasota, Hardee, and DeSoto Counties, and portions of Hillsborough, 

Charlotte, Polk, and Highlands Counties. 


The Peace River watershed accounts for about 46 percent of the land 

area of the SWUCA and 48 percent (627 mgd) of the total 1996 ground 

water withdrawals in the SWUCA. 


The Myakka River watershed lies entirely within the SWUCA. The 

SWFWMD also continues to monitor the effects of lowered ground water 

levels throughout the region on the movement of the freshwater/saltwater 

interface and lake levels. 

Additionally, most of the watershed above upper Lake Myakka lies in 

the Eastern Tampa Bay WUCA and abuts the Most Impacted Area, an 

area where no new water withdrawals are allowed. 

Major Water Quality Trends 


A 1992 SBNEP study found the following trends in Sarasota Bay: 

1. Nitrogen loads had increased by approximately 480 percent, compared 

with pristine conditions; 

2. Tidal wetlands had decreased by approximately 39 percent between 

1950 and 1990 estimates; 

3. Dredging activities had degraded 14 percent of the bay bottom;


47 

4. Dredge and fill activities, as well as reduced water quality, had 

caused a 30 percent loss of seagrasses between 1950 and 1988; and 

5. Fisheries had declined substantially. 

Upper and lower Sarasota Bays, as well as Dona and Roberts Bays, have 

exhibited improving water quality trends over the past several years, with 

most of the improvements occurring between 1990 and 1992. Nitrogen 

loads decreased 47 percent baywide when comparing 1998 and 1988 values. 

Before 1990, the average Trophic State Index values for all these systems 

were “fair” (with their values ranging from 50–59). 

The improvements in water quality between 1990 and 1992 were 

concurrent with the completion of nutrient removal technology upgrades 

to the city of Sarasota’s wastewater treatment plant (in 1991), as well as the 

movement toward the deep-well injection of effluent from facilities such 

as Manatee County’s Southeast Treatment Plant and Atlantic Utilities’ 

discharge into Phillippi Creek. These changes were a result of the Grizzle- 

Figg Act (Section 403.086, F.S.), which required advanced wastewater 

treatment (i.e., nutrient removal technology) for all surface water discharges 

into Sarasota Bay. 

A 1999 SBNEP study found that out of 17 baywide segments used to 

delineate Sarasota Bay, 11 showed trends of decreasing chlorophyll a concentrations, 

an indication of increased water quality. Additionally, 5 bay 

segments showed trends of increasing water clarity, 5 showed decreasing 

trends for total nitrogen (TN) concentrations, 7 showed improvements for 

total phosphorus (TP) concentrations, and 4 showed improving trends for 

total suspended solids (TSS) concentrations. 

Areas with multiparameter documented improvements in water 

quality in recent years include the waters offshore Tidy Island, the area 

influenced by the city of Sarasota’s wastewater outfall, and Little Sarasota 

Bay, respectively. Upgrades to the city of Sarasota’s wastewater plant and 

improvements to Manatee County’s wastewater irrigation practices may 

be responsible for the improvements in water quality offshore Tidy Island. 

Determining the causes of improved water quality in Little Sarasota Bay, 

however, is more problematic. 

Because of the implementation of nutrient removal technology and 

increased reuse of treated effluent, nitrogen loading into Whitaker Bayou 

decreased by approximately 95 percent between 1990 and 2000. This 

amounts to a 43 percent decline in loads throughout the central portion of 

the bay. During this period, nutrient levels decreased in the waters offshore 

from Whitaker Bayou. Between 1988 and 1996, seagrass coverage in 

central Sarasota Bay increased by 669 acres. 

In contrast, water quality may be declining in the eastern portion of 

Sarasota Bay between Stevens Point and Bowlees Creek. Through 1992, 

water quality in Roberts Bay and Palma Sola Bay did not appear to be 

either increasing or decreasing. 

Between 1970 and 1992, the majority of Sarasota Bay became less 

saline, despite the lack of a trend in rainfall in the immediate watershed 

during the same period. This change is thought to be related to increases


in impervious surface area that have accompanied the increased urbanization 

of the watershed. 

Since 1950, intertidal wetlands in Sarasota Bay’s watershed have 

declined by approximately 40 percent. Although not as well documented, 

similar losses have also occurred in the watersheds of Dona and Roberts 

Bays. These wetlands provide a number of benefits, including shoreline 

stabilization, water quality improvement, and fish and wildlife habitat. 


Nutrient Concentrations and Trends 

Natural environmental factors and human activities have combined to 

produce extremely large phosphorus loadings to surface waters in the Peace 

River watershed. As a result, a number of fresh waterbodies in the watershed 

have become severely degraded and currently exhibit hypereutrophic 

water quality conditions year-round. Nitrogen loadings have not reached 

such elevated levels; on a relative basis, water quality in the estuarine segments 

of the Peace River is less affected than in many freshwater portions 

of the system. Nutrient-driven phytoplankton blooms occur seasonally in 

the tidal river and upper Charlotte Harbor, however, and periodically cause 

chlorophyll a concentrations to reach levels that would be characterized as 

hypereutrophic in some estuarine classification systems. 

In recent decades, three waterbodies in the Upper Peace River watershed 

(Lake Parker, Banana Lake, and Lake Hancock), along with their 

tributaries (Stahl Canal, Banana–Hancock Canal, and Lake Lena Run), 

have consistently exhibited some of the poorest water quality in the state. 

Reduced point source discharges and recent restoration efforts implemented 

by the SWFWMD, the Department, and local governments have 

produced water quality improvements in Lake Parker and Banana Lake. 

Despite these improvements, however, both waterbodies remain highly 

eutrophic. 

Lake Hancock, a hypereutrophic system, discharges extremely poor 

quality water to Saddle Creek and Upper Peace River. Discharges from 

the lake, which are characterized by high concentrations of phytoplankton 

cells and other sources of biological oxygen demand (BOD), have caused 

faunal mortality and long-term water quality impacts extending many 

miles downstream along the river’s main stem. Those discharges are also 

a potential contributing factor in the water quality problems experienced 

periodically at the PRMRWSA drinking water facility on the Lower Peace 

River. The degradation of Lake Hancock is attributed to flows from its 

tributaries, which have received elevated nutrient loadings over several 

decades from a number of industrial and domestic point sources. 

Although still extremely high, phosphorus concentrations have shown 

improving trends in recent decades in some portions of the Peace River 

watershed. Concentrations of dissolved inorganic phosphate (DIP) and 

TP have declined at several long-term U.S. Geological Survey (USGS) 

monitoring sites. These improvements appear due to increased oversight by 

regulatory agencies and increased compliance by regulated industries and 

local governments, leading to reduced phosphorus loadings from a number


49 

of phosphate mining and processing facilities, food processing facilities, 

and municipal wastewater treatment plants. Despite these trends, however, 

average annual TP concentrations measured at the Bartow, Homeland, Fort 

Meade, Zolfo Springs, and Arcadia USGS gage sites from 1990 to 1995 

exceeded 1.0 mg/L and thus fell within the range observed in the most 

degraded 10 percent of Florida streams. 

Elevated DIP concentrations and low ratios of dissolved inorganic 

nitrogen (DIN) to DIP contribute to the development of nuisance cyanobacterial 

blooms in fresh waters. These blooms are most likely to occur 

in quiescent areas such as lakes and floodplain sloughs, where a combination 

of high nutrient concentrations and low current velocities allow dense 

phytoplankton populations to develop and persist. The frequent development 

of cyanobacterial blooms in many surface waters in the Peace River 

watershed and episodic complaints of unpleasant tastes and odors caused 

by cyanobacterial metabolites in public water supplies provided by the 

PRMRWSA, are symptoms of very high phosphorus concentrations in 

the system. 

In recent decades, the concentrations of DIN appear to have declined 

somewhat along the river’s main stem at the Fort Meade, Zolfo Springs, 

and Arcadia sites, and have fluctuated with no apparent trend at the Saddle 

Creek, Bartow, and Homeland sites. Increasing trends are evident at the 

Charlie Creek, Joshua Creek, Horse Creek, and Shell Creek sites. TN concentrations 

show similar temporal changes. The increasing trends observed 

in several of the tributary creeks are cause for concern, and signal increasing 

anthropogenic nutrient loadings to stream systems that were traditionally 

among the least degraded in the Peace River system. 

Except for the Shell Creek–Punta Gorda gage site, average TN concentrations 

at each of the USGS monitoring locations in the Peace River 

watershed exceeded 1.4 mg/L from 1990 to 1995, the 60th percentile value 

for Florida streams. 

Annual Nutrient and Total Suspended Solids Loadings. A 1995 

study by Coastal Environmental Inc., estimated average annual loadings of 

TN, TP, and TSS to gaged and ungaged segments of Charlotte Harbor, the 

Peace and Myakka Rivers, and their major tributaries from 1985 to 1991. 

Upper Charlotte Harbor received the bulk of its estimated annual TN, 

TP, and TSS loadings from the Peace River watershed, and in many ways 

can be considered an extension of the watershed for the purposes of water 

quality analysis. 

Among hydrologic subbasins in the Peace River watershed, those 

upstream of the USGS gages at Bartow and Zolfo Springs generated the 

largest annual loadings of TN, TP, and TSS. Industrial point sources 

contributed large proportions of the estimated TN, TP, and TSS loadings 

in these subbasins. 

Conductivity Patterns and Trends. Conductivity, a water quality 

indicator that normally varies in west-central Florida surface waters as a 

function of ground water or saltwater inputs, shows complex spatial and 

temporal variability in the Peace River watershed. At monitoring sites in 

the predominantly freshwater portion of the system (e.g., the USGS gage 

sites extending from Saddle Creek–P11 to Shell Creek–Punta Gorda),


variations in the conductivity of surface waters are primarily driven by fluctuations 

in ground water discharge. In the predominantly estuarine portion 

of the system (e.g., the SWFWMD/SWIM monitoring sites extending 

from Peace River–Mary Point to Boca Grande Pass), variations are primarily 

caused by fluctuating inputs of fresh water and salt water from the Peace 

River and the Gulf of Mexico, respectively. 

In freshwater portions of the watershed, temporal conductivity trends 

can be used as a surrogate to examine trends in ground water discharge. 

During recent decades, conductivity has declined at the Saddle Creek–P11, 

Peace–Bartow, and Peace–Zolfo gage sites, presumably reflecting reduced 

ground water discharges. Increasing trends occurred at the Peace River– 

Homeland, Charlie Creek–Gardner, Joshua Creek–Nocatee, Horse Creek– 

Arcadia, and Shell Creek–Punta Gorda gage sites, presumably reflecting 

increased ground water discharges in these areas. Temporal changes in 

ground water discharge result from a complex combination of natural 

causes (e.g., rainfall) and anthropogenic causes (e.g., domestic, industrial, 

and agricultural ground water use). 

Dissolved Oxygen. From 1990 to 1995, minimum dissolved oxygen 

(DO) concentrations below 4.0 mg/L (considered biologically stressful) 

and below 2.0 mg/L (lethal to many organisms) were observed at many of 

the USGS and SWIM monitoring sites in the watershed. Depressed DO 

concentrations can occur naturally in productive subtropical aquatic systems, 

where elevated water temperatures reduce oxygen solubility and high 

biological productivity leads to increased BOD. Anthropogenic loadings of 

nutrients and BOD are exacerbating this situation in many waterbodies in 

the Peace River watershed. 

Subbasin Trends 

The following sections describe trends in each segment of the Peace 

River. 

Peace River above Bartow. From 1990 to 1995, the average annual 

TP concentration measured at the USGS monitoring site at Bartow 

exceeded 1.2 milligrams of phosphorus per liter (mg P/L), placing water 

quality in this river reach among the poorest 10 percent of Florida streams. 

During the same period, the average TN concentration exceeded 2.2 milligrams 

of nitrogen per liter (mg N/L), placing it among the poorest 20 percent 

of Florida streams. This reach of the river receives discharges from the 

Saddle Creek and Peace Creek subbasins. 

Between 1985 and 1991, nonpoint source runoff and permitted industrial 

discharges were the largest loading sources for this portion of the river, 

contributing 56 percent and 40 percent of the estimated N load, 91 percent 

and 6 percent of the estimated P load, and 83 percent and 17 percent of the 

estimated TSS load, respectively. Urban and rangeland land uses contributed 

large proportions of the anthropogenic nonpoint source loadings, 

while a combination of citrus processing facilities and distillers made up 

the bulk of the industrial point source discharges. 

From 1940 to 1993, stream flow measured by the USGS at Bartow 

decreased by 42 percent.


51 

Saddle Creek. Eutrophication driven by excessive nutrient loadings is 

the most serious water quality problem in this subbasin, which includes a 

number of hypereutrophic lakes (Lake Parker, Lake Hancock, and Banana 

Lake) and streams (Saddle Creek, Banana–Hancock Canal, and Lake Lena 

Run). From 1990 to 1995, the average annual TP concentration measured 

at the USGS monitoring site on Saddle Creek at Structure P-11 (immediately 

south of Lake Hancock) exceeded 0.4 mg P/L, placing water quality 

in this river reach among the poorest 25 percent of Florida streams. During 

the same period, the average TN concentration exceeded 5.2 mg N/L, 

among the poorest 10 percent of Florida streams. 

Several lakes in the subbasin have received excessive nutrient loadings 

over several decades, and in response have developed extensive deposits of 

nutrient-enriched organic sediments. 

Peace River—Bartow to Zolfo Springs. From 1990 to 1995, the 

average TP concentration measured at the USGS monitoring sites at Homeland, 

Fort Meade, and Zolfo Springs exceeded 1.0 mg P/L, placing water 

quality in this river reach among the poorest 10 percent of Florida streams. 

During the same period, the average TN concentrations exceeded 1.8 mg 

N/L, a value that ranks among the poorest 30 percent of Florida streams. 

As with the river reach above Bartow, nonpoint source runoff and 

permitted industrial discharges are the largest loading sources, contributing 

64 percent and 35 percent of the estimated N load, 18 percent and 

81 percent of the estimated P load, and 70 percent and 30 percent of the 

estimated TSS load, respectively, from 1985 to 1991. Rangeland, mining, 

urban, and agricultural land uses contribute large proportions of the 

anthropogenic nonpoint source loadings, while phosphate mining and processing 

facilities make up the bulk of the industrial point source discharges. 

From 1934 to 1993, stream flow measured by the USGS at Zolfo 

Springs declined by 26 percent. 

Peace River—Zolfo Springs to Arcadia. From 1990 to 1995, the 

average TP concentration measured at the USGS monitoring site on the 

Peace River at Arcadia exceeded 1.0 mg P/L, placing water quality in this 

river reach among the poorest 10 percent of Florida streams. During the 

same period, the average TN concentration exceeded 1.6 mg N/L, a value 

that is among the poorest 30 percent of Florida streams. 

Nonpoint source runoff is the largest loading source for this segment of 

the river, contributing more than 99 percent of the estimated loads of N, P, 

and TSS from 1985 to 1991. The pasture/rangeland land use category contributed 

more than 75 percent of the anthropogenic nonpoint source N and 

P loadings from 1985 to 1991, while the combination of pasture/rangeland 

and urban land uses contributed more than 75 percent of the estimated 

TSS load. 

From 1933 to 1993, stream flow measured by the USGS at Arcadia 

decreased by 10 percent. 

Horse Creek. From 1990 to 1995, the average TP concentration 

measured at the USGS monitoring site on Horse Creek near Arcadia 

was 0.44 mg P/L, placing water quality in this river reach near the poorest 

20 percent of Florida streams. During the same period, the average


TN concentration was 1.77 mg N/L, placing the site among the poorest 

30 percent of Florida streams. 

Nonpoint source runoff is the largest loading source, contributing 

more than 99 percent of the estimated N, P, and TSS loads from 1985 to 

1991. The pasture/rangeland land use category was estimated to contribute 

more than 75 percent of the anthropogenic nonpoint source N and P 

loadings from 1985 to 1991, and more than 70 percent of the estimated 

TSS load. 

Concentrations of DIN measured at the Horse Creek gage site in 

recent years are substantially higher than concentrations observed in the 

early 1980s, presumably as a result of changing land uses in the contributing 

drainage basin. Because Horse Creek has traditionally represented one 

of the least affected tributaries in the Peace River watershed, increasing 

nutrient concentrations are a matter of considerable concern. 

Joshua Creek. From 1990 to 1995, the average TP concentration 

measured at the USGS monitoring site on Joshua Creek at Nocatee was 

0.24 mg P/L, placing water quality in this river reach among the poorest 

30 percent of Florida streams. During the same period, the average TN 

concentration exceeded 2.0 mg N/L, placing the site among the poorest 

20 percent of Florida streams. 

Prairie Creek/Shell Creek. From 1990 to 1995, the average TP concentration 

measured at the USGS monitoring site on Prairie Creek (near 

Fort Ogden) was 0.10 mg P/L, placing the site near the median of Florida 

streams. The average TN concentration was 1.5 mg N/L, placing the creek 

among the poorest 35 percent of Florida streams. The average TP concentration 

measured at the Shell Creek site (near Punta Gorda) was 0.20 mg 

P/L, among the poorest 30 percent of Florida streams. The average TN 

concentration was 1.2 mg N/L, near the median of Florida streams. 

From 1971 to 1995, increasing trends were evident in TP and (possibly) 

DIP concentrations at the Prairie Creek–Fort Ogden gage site. Insufficient 

data were available to assess trends in DIN or TN during this period. 

Data from the Shell Creek–Punta Gorda site showed no apparent trend in 

DIP or TP concentrations but an increase in DIN and a possible increase 

in TN over the period. Because they are occurring in tributaries that were 

traditionally among the least affected in the Peace River watershed, these 

increasing nutrient concentrations are a matter of concern. 

Tidal Peace River and Charlotte Harbor. With assistance from the 

Department and Environmental Quality Laboratory, Inc., the SWFWMD 

has conducted monthly monitoring of water quality conditions at 4 sites in 

the tidal Peace River and 10 sites in Charlotte Harbor since 1993. Salinity 

conditions from 1993 to 1995 ranged from tidal fresh (less than 0.5 parts 

per thousand [ppt] salinity) to oligohaline (less than 5 ppt) at the most 

upstream Peace River sampling site (CH-029), located above Mary Point 

in the river’s main channel. Mesohaline conditions (10 to 20 ppt) prevailed 

at the remaining river sites, which are at the U.S. Highway 41 bridge 

(CH-004), the mouth of Alligator Bay (CH-05B), and the river mouth 

(CH-005). Polyhaline conditions (25 to 35 ppt) predominated in lower 

Charlotte Harbor (CH-011) and Boca Grande Pass (CH-013, CH-014).


53 

Salinity regimes in the tidal Peace River reflect the mixing of fresh 

and marine waters, and vary in response to changing freshwater inflows 

from the Peace River watershed. Because the low-salinity habitats present 

in tidal rivers provide important habitat for the larval and juvenile 

stages of many estuarine fish and shellfish species, the SWIM Program has 

attempted to develop resource-based freshwater inflow and salinity targets 

for this river reach. The results suggest that from 1966 to 1993, freshwater 

inflow to Charlotte Harbor at the mouth of the Peace River exhibited 

a 6 percent reduction that cannot be explained on the basis of rainfall 

reductions alone. 

The Peace River represents the largest single source of nutrient loadings 

to upper Charlotte Harbor, and nutrient concentrations measured at the 

SWIM monitoring sites show clear gradients that extend from the river to 

the upper and lower harbor and Boca Grande Pass. Average TP concentrations 

at the Mary Point site exceeded 0.70 mg/L from 1993 to 1995, placing 

water quality in this river reach among the poorest 20 percent of Florida 

streams. TP concentrations declined to 0.25 mg/L at the river mouth and 

0.04 mg/L in Boca Grande Pass, reflecting progressive dilution by lowernutrient 

estuarine and Gulf of Mexico waters. 

Average chlorophyll a concentrations observed from 1993 to 1995 

ranged from less than 10 micrograms per liter (µg/L) at the tidal fresh/ 

oligohaline Mary Point site, where low residence times caused by high 

rates of river flow presumably inhibited the development of dense algal 

populations, to greater than 15 µg/L in mesohaline reaches of the lower 

river. In Florida estuaries, annual average chlorophyll a concentrations 

below 10 µg/L are considered indicative of “good” water quality, and values 

exceeding 10 µg/L are considered indicative of “fair” water quality. Very 

high chlorophyll a concentrations (greater than 80 µg/L), indicating the 

presence of algal blooms, were observed episodically at the U.S. Highway 

41 and river mouth stations from 1993 to 1995. These values indicate 

hypereutrophic water quality conditions in some estuarine classification 

systems (e.g., National Oceanic and Atmospheric Administration, 1995). 

Long-term data collected by Environmental Quality Laboratory, Inc., indicate 

that such blooms have occurred seasonally since regular monitoring 

began in 1976. 

Minimum DO levels frequently fell below 2 mg/L at the tidal Peace 

River and upper Charlotte Harbor monitoring sites from 1993 to 1995. 

These hypoxic conditions are highly stressful and potentially lethal to many 

estuarine animals. As with phytoplankton blooms, however, long-term 

studies indicate that seasonal hypoxia has occurred in the area since regular 

monitoring was initiated in 1976. Hypoxic events typically occur during 

periods of high river flow, when the water column becomes vertically stratified 

and a layer of fresh water flows with little mixing over a layer of salty, 

higher density bottom water. 


Annual minimum phosphorus and ammonium concentrations 

show increasing trends at a long-term monitoring site immediately south 

of Upper Myakka Lake in Myakka River State Park. The average TP


concentration measured at the site from 1970 to 1998 was 0.39 mg/L, a 

value that is near the 75th percentile of Florida streams. 

Subbasin Trends 

The following sections describe trends in each segment of the Myakka 

River. 

Myakka River at Myakka City (USGS Gage 02298608). From 

1990 to 1995, the average annual TP concentration measured at the site 

exceeded 0.3 mg P/L, greater than the 70th percentile value for Florida 

streams. More than 90 percent of the TP was in the form of DIP, which is 

readily available for uptake by algae and other aquatic plants. Two major 

industrial point source discharges (greater than 0.1 mgd) are located in this 

subbasin. 

From 1990 to 1995, the average TN concentration was less than 1 mg 

N/L, a value below the median concentration observed in Florida streams. 

TN concentrations showed a decreasing trend at the site from 1976 to 

1995, although annual average DIN concentrations remained above levels 

that would limit algal growth. Conductivity increased at the site between 

1976 and 1995, indicating increased off-site seepage of irrigation waters in 

the surrounding watershed. 

Myakka River at Sarasota (USGS Gage 02298830). From 1970 

to 1998, the average annual TP concentration measured at the site was 

0.39 mg P/L, greater than the 70th percentile value for Florida streams. 

More than 90 percent of the TP was in the form of DIP. 

Between 1970 and 1998, the average total Kjeldahl nitrogen (TKN) 

concentration was 1.31 mg N/L, a value that is just above the median 

concentration observed in Florida streams. TKN concentrations showed 

no trend at the site from 1970 to 1998. Conductivity increased from 1970 

to 1998, indicating increased off-site seepage or irrigation waters in the 

surrounding watershed. 

Myakka River near Laurel (USGS Gage 022988900). From 1990 

to 1992, the average annual TP concentration measured at the site was 

0.34 mg P/L, exceeding the 70th percentile value among Florida streams. 

More than 90 percent of the TP was in the form of DIP. The average TN 

concentration was 1.27 mg N/L, which is slightly above the median concentration 

observed in Florida streams. 

Nutrient concentrations showed no clear increasing or decreasing 

trends at the site from 1988 to 1992. DIP concentrations are well above 

levels that would be expected to limit algal growth, DIN concentrations 

are relatively low, and the average DIN:DIP ratio is less than 1, suggesting 

that primary production in the water column may be nitrogen limited in 

this river reach. Conductivity showed a possible increasing trend (simple 

regression, p=0.06) at the site from 1988 to 1992, perhaps reflecting 

increasing discharges of ground water to surface waters in the contributing 

drainage basin. 

Deer Prairie Slough near North Port Charlotte (USGS Gage 

02299160). From 1997 to 1999, the average annual TP concentration 

measured at this gage site was 0.25 mg P/L, which is above the median 

value for Florida streams. Fifty-six percent of the TP was in the form 

of DIP.


55 

Big Slough Canal near Myakka City (USGS Gage 02299410). 

From 1997 to 1999, the average annual TP concentration measured here 

was 0.36 mg P/L, exceeding the 70th percentile value for Florida streams. 

On average, 78 percent of the TP was in the form of DIP. 

Tidal Myakka River and Charlotte Harbor. The SWFWMD’s 

SWIM Department, with assistance from the Department and Environmental 

Quality Laboratory, Inc., has conducted monthly monitoring of 

water quality conditions at 3 sites in the tidal Myakka River and 11 sites in 

other portions of Charlotte Harbor since 1993. Salinity conditions from 

1993 to 1996 at the most upstream Myakka River sampling site (CH-1) 

near the mouth of Rock Creek in the river’s main channel were oligohaline 

(less than 5 ppt). Mesohaline conditions (10 to 20 ppt) prevailed at 

the remaining Myakka River sites, which are located at the CR-776 bridge 

(CH-2) and the mouth of Tippecanoe Bay (CH-2B). Mesohaline conditions 

also predominated in upper Charlotte Harbor (CH-6) and along the 

western shoreline (CH-9B), where freshwater inputs from the Peace and 

Myakka Rivers heavily influence salinity levels. Somewhat higher salinities 

(20 to 25 ppt) were observed along the eastern shoreline (CH-7) and in the 

middle harbor (CH-9), indicating that Gulf waters are less diluted by riverine 

inputs in these areas. The Myakka River is a much smaller source than 

the Peace River of TN, TP, and TSS loadings to upper Charlotte Harbor. 

Average chlorophyll a concentrations observed in the Lower Myakka 

River from 1993 to 1996 ranged from less than10 µg/L at Stations MY-1 

and MY-3 to greater than 12.5 µg/L at Station MY-2. Maximum chlorophyll 

a concentrations from 1993 to 1996 were greater than 10 µg/L at 

Station MY-1. As a general rule, phytoplankton production appears to vary 

seasonally between light limitation (due to elevated water color and low 

light penetration during periods of high river flow) and nitrogen limitation 

(due to the reduced availability of DIN) in the Lower Myakka River and 

upper Charlotte Harbor. 

Minimum DO levels occasionally fell below 4 mg/L at the Lower 

Myakka River monitoring sites (MY-1 and MY-2), and below 2 mg/L at the 

third site at the Lower Myakka River (MY-3) from 1993 to 1996. DO concentrations 

below 4 mg/L are considered stressful and concentrations below 

2 mg/L are potentially lethal to many estuarine animals. Long-term studies 

indicate that seasonal hypoxia (operationally defined as DO less than 4 

mg/L) has occurred in northern Charlotte Harbor since regular monitoring 

was initiated in 1976. 

Watershed Management Activities and 

Processes 

Over the years, management plans and activities in the Sarasota Bay 

and Peace and Myakka Rivers Basin have been implemented to eliminate 

wastewater discharges; reduce the discharges of polluted stormwater from 

urban and agricultural areas; and protect, preserve, and restore special 

areas. The following section describes historical, current, and ongoing 

activities and processes to address water quality problems.


Much of the progress in the basin for developing water quality restoration 

plans and implementing watershed and water quality improvements is 

attributable to coordinated local, state, and regional efforts. Many plans 

share common goals, and their implementation is based on various groups 

playing critical roles in planning, funding, managing, and executing 

projects. The Department continues to coordinate its efforts with these 

entities to obtain data, strengthen monitoring activities, and exchange 

information through periodic meetings. 

Major Programs and Projects 

A number of major restoration initiatives, if continued, will have 

significant positive effects on the basin’s water quality. 


Sarasota Bay National Estuary Program. Sarasota Bay became part 

of the National Estuary Program in 1989, and a Comprehensive Conservation 

and Management Plan (CCMP) for the bay was approved and signed 

by all participating agencies in 1995. The CCMP recommends specific 

actions to be taken by local governments and state and federal agencies 

to improve and protect the bay. These actions include upgrading wastewater 

treatment plants, pursuing the reuse of wastewater on a large scale, 

restoring and protecting bay habitats, and constructing stormwater retrofit 

projects. 

Because of upgrades to private and public wastewater treatment 

plants, point source nitrogen loads to Sarasota Bay have been reduced 

from 569 tons per year in 1988 to 110 tons per year in 1999, an 81 percent 

decline. In response, water clarity improved in 7 of 13 bay segments 

between 1983 and 1998, and degraded in only 1 of 13 bay segments. As 

water clarity improved, seagrass coverage increased as well, with 596 additional 

acres found in 1999, compared with 1988. 

In addition to treatment plant upgrades, the Sarasota Bay region now 

reclaims approximately 46 percent of its wastewater treatment plant effluent 

for various reuse projects, and numerous stormwater treatment systems 

have been put in place to further reduce nutrient and toxin loads to the bay. 

In combination with various local, regional, state, and federal agencies, 

habitat restoration projects in the Sarasota Bay region have enhanced or 

created approximately 200 acres of fisheries habitat through wetland restoration 

and the removal of exotic vegetation. Additional habitat has been 

created through the deployment of various types and sizes of artificial reefs, 

ranging from large, complex systems such as the reef placed offshore from 

Leffis Key, to small concrete structures designed to fit at the base of various 

channel markers. 

Sarasota Bay Surface Water Improvement and Management Plan. 

The goal of the Sarasota Bay SWIM Plan, completed in 1997 and updated 

in 2002, is to outline a series of research and/or restoration projects that 

will allow for the preservation and continued restoration of the health of 

Sarasota Bay, in spite of an increased human population in the contributing 

watershed.


57 

Strategies to accomplish this task focus on improving and protecting 

water quality through continued efforts to treat wastewater and stormwater, 

as well as continued efforts to restore wetlands and create artificial 

reefs. Additional research efforts are also needed to understand better the 

relationship between air quality and water quality, as well as to understand 

better the impacts to the bay’s health that may have been caused by various 

alterations to the patterns of freshwater inflow into the bay. This plan 

will serve as the guidance document that coordinates the efforts of the 

SWFWMD with those of the various local, regional, state, and federal 

agencies, as well as private interests, to restore and protect Sarasota Bay. 

Southwest Florida Water Management District’s Comprehensive 

Watershed Management Program, Southern Coastal Watershed 

Project. The SWFWMD initiated the Comprehensive Watershed 

Management (CWM) Program to improve the management of water 

and related natural resources. This initiative employs a watershed-based 

approach to resource management. Staff members from a variety of disciplines 

and departments make up the “watershed teams” that are assigned 

to 11 primary watersheds. CWM is a science-based approach that includes 

the application of geographic information system technology and other 

modeling tools in each basin. 

Each watershed team is charged with developing a watershed management 

plan. The CWM plans analyze the wealth of information available 

in each area, identify issues, and recommend specific actions to address 

these issues. Completed CWM plans become a part of the District Water 

Management Plan. These plans, which reflect a “snapshot-in-time” for the 

watershed, are periodically updated. 

Partnering with local governments is essential to the success of the 

CWM initiative. Local governments are involved in identifying issues, 

developing preventive or remedial strategies, and carrying out coordinated 

implementation. 

The Southern Coastal watershed, including Sarasota Bay, was designated 

as a priority watershed for evaluation using the CWM approach. 

The Southern Coastal watershed is highly developed, particularly in the 

northern portions in Manatee and Sarasota Counties. Fortunately, many 

resource assessments have been completed in the Southern Coastal watershed, 

and much information already exists to aid in the evaluation of potential 

issues associated with protecting and managing water resources. 

Sarasota County Comprehensive Watershed Management Program. 

The goal of the Sarasota County Comprehensive Watershed Management 

Program is to integrate the water-related disciplines of engineering, 

biology, and water chemistry, as well as the functions of design, permitting, 

project management, and operations, into a comprehensive program for 

water resource protection in the county. This effort has culminated in 

the creation of a common identifier for all water programs, known as the 

Center for Watershed Management. The water programs that make up 

the center include Utilities, Stormwater, Drainage Operations, Mitigation/ 

Permitting/Restoration, Resource Protection, Water Quality, and Water 

Resources.



Charlotte Harbor National Estuary Program. CHNEP was established 

in 1995 to provide long-term protection for Charlotte Harbor and its 

watershed, which extends over 4,400 square miles and includes the Peace 

and Myakka River watersheds. The CCMP was approved and signed by 

all participating agencies in 2000. 

CHNEP’s principal goals are as follows: 

1. Improve the environmental integrity of the Charlotte Harbor study 

area; 

2. Preserve, restore, and enhance seagrass beds, coastal wetlands, barrier 

beaches, and functionally related uplands; 

3. Reduce point and nonpoint sources of pollution to attain desired 

uses of the estuary; 

4. Provide the proper freshwater inflow to the estuary to ensure a 

balanced and productive ecosystem; 

5. Develop and implement a strategy for public participation and 

education; and 

6. Develop and implement a formal Charlotte Harbor management 

plan with a specified structure and process for achieving goals for 

the estuary. 

The following priority problems for the region were identified: 

Hydrologic Alteration—Adverse changes to amounts, locations, and 

timing or freshwater flows, the hydrologic function of floodplain systems, 

and natural river flows. 

Water Quality Degradation—These problems include pollution 

from agricultural and urban runoff, point source discharges, septic tank 

loadings, atmospheric deposition, and ground water. 

Fish and Wildlife Habitat Loss—The degradation and elimination 

of headwater streams and other habitats caused by development, the conversion 

of natural shorelines, the cumulative impacts of docks and boats, 

invasive exotic species, and cumulative and future impacts. 

Charlotte Harbor Surface Water Improvement and Management 

Plan. The Charlotte Harbor SWIM Plan, completed in 1993 and updated 

in 2000, covers the portion of the Charlotte Harbor Basin within the 

SWFWMD’s jurisdiction, which includes the Myakka and Peace River 

watersheds and some coastal watersheds. It excludes the tidal Caloosahatchee 

River and areas in the South Florida Water Management District 

and thus does not include all of the CHNEP, although the two efforts 

coordinate closely. 

The update to the plan focuses on four primary issues: 

• Protection of water quality in the estuary and its tributaries, with 

emphasis on prevention of excessive nutrient enrichment; 

• Protection of optimum freshwater flows to the estuary;


59 

• Habitat protection and restoration, with emphasis on the acquisition 

of select parcels; and 

• Development of public education and public involvement programs, 

to inform citizens of problems affecting the waterbody and their 

potential solutions. 

The SWIM plan is structured around five major themes (initiatives): 

program coordination, water quality protection, assurance of optimal freshwater 

inputs, habitat protection and restoration, and public education and 

involvement. A series of projects addressing those themes has been implemented, 

including the following: 

• A diagnostic assessment of pollution sources in the Charlotte Harbor 

Basin, including the Myakka and Peace River watersheds, 

• The development of resource-based freshwater inflow and salinity 

targets for the tidal Peace River, 

• The design of a long-term monitoring program for the estuary and 

tidal portions of the Myakka and Peace Rivers, 

• An assessment of the causes of hypoxia (DO less than 2 mg/L) in 

Charlotte Harbor, 

• The mapping of status and trends (if any) in streamside vegetation in 

the tidal Peace River and Myakka River, 

• The mapping of seagrass status and trends in Charlotte Harbor, and 

• An assessment of the causes of light attenuation in Charlotte Harbor. 

The SWIM Program also recently completed a number of habitat 

restoration projects, including 15 acres in Punta Gorda, 20 acres in Alligator 

Creek, 76 acres at Don Pedro Island, and 160 acres on the Cape Haze 

peninsula. Additional projects, addressing the development of resourcebased 

water quality and pollutant loading targets for the tidal Myakka and 

Peace Rivers and other priority issues, are currently under way. 


Watershed Management Program, Peace River Watershed Project. 

(See the Sarasota Bay section earlier in this chapter for general information 

on the CWM Program.) 

The Peace River watershed was designated as a priority watershed for 

evaluation using the CWM approach due, in part, to impacts to surface 

waters resulting from human activities such as citrus and row crop production, 

phosphate mining and processing, cattle production, food processing, 

and urbanization. These land uses have increased loadings of nutrients and 

other pollutants to many waterbodies in the Peace River watershed. The 

wildlife habitat values and functional integrity of a large proportion of the 

watershed have also been adversely affected. In many developed areas, the 

threat of recurrent flooding is a major concern.


Winter Haven Chain of Lakes Surface Water Improvement and 

Management Program. The SWFWMD is currently updating the 1990 

SWIM Plan developed for the lakes. The primary goals identified in the 

initial plan are the improvement of water quality and associated natural 

systems throughout the chain of lakes. Major issues affecting water quality 

and natural systems include stormwater runoff, point source discharges, 

excessive cattail growth, the preservation of fish and wildlife, a comprehensive 

water and nutrient budget, the reduction of septic system discharges, 

lake level management, the management of nutrient releases from lake 

bottom sediments, and improved growth management. 

Peace River Basin Land Acquisition Programs. 

Southwest Florida Water Management District Land Acquisition 

Program. In partnership with the Nature Conservancy, the SWFWMD 

negotiated the Bright Hour Watershed Project, the single largest less-thanfee 

acquisition ever executed in Florida. The project ensures the long-term 

protection of an extraordinary 28,274-acre tract in DeSoto County. 

Polk County. In 1994, Polk County voters approved the creation of a 

land acquisition program, funded by ad valorem taxes, to pursue the preservation 

and protection of environmentally sensitive lands in the county. 

To date, the county has acquired 2,700 acres through joint acquisition 

partnerships with the Florida Communities Trust and the SWFWMD. 

Upper Peace River Ecosystem Planning Committee. The Upper 

Peace River Ecosystem Planning Committee (UPREPC) was created to 

serve as a forum for the interagency review of mitigation options related to 

the construction of the Polk County Parkway and other large-scale development 

projects. The committee’s responsibilities were established through 

a Memorandum of Understanding executed by the U.S. Army Corps 

of Engineers, the Department, Florida Department of Transportation, 

Florida Fish and Wildlife Conservation Commission, and SWFWMD. 

To date, UPREPC has focused almost exclusively on mitigation potential 

in the Teneroc Fish Management Area. The committee may ultimately 

coordinate mitigation and mine reclamation throughout the Peace River 

watershed. The progress and effectiveness of the group will be monitored, 

and the efforts of the Peace River CWM team will be coordinated with the 

UPREPC to the greatest extent possible. 


Charlotte Harbor National Estuary Program. (See the Peace River 

section earlier in this chapter for general information on CHNEP.) 

Charlotte Harbor Surface Water Improvement and Management 

Plan. (See the Peace River section earlier in this chapter for general information 

on the Charlotte Harbor SWIM Plan.) 


Watershed Management Program, Myakka River Watershed Project. 

(See the Sarasota Bay section earlier in this chapter for general information 

on the CWM Program.) 

Approximately $44 million has been designated for Myakka 

River CWM projects. This does not include the many other resource


61 

management activities undertaken by local governments, the Department, 

and others. 

Charlotte Harbor Aquatic and State Buffer Preserves Program. 

Gasparilla Sound and Charlotte Harbor Aquatic Preserve is one of 

42 aquatic preserves statewide and one of 6 aquatic preserves in the Charlotte 

Harbor estuary complex. Gasparilla Sound–Charlotte Harbor, which 

was designated an aquatic preserve in 1979, encompasses 79,168 acres. 

Aquatic preserve management activities include resource management, 

research, and education aimed at maintaining and enhancing existing 

resources. The Department manages the preserve. A citizen organization, 

the Friends of the Charlotte Harbor Aquatic Preserves, assists the Department’s 

field office in achieving management goals. 

Myakka River Wild and Scenic River Management Plan. In 1978, 

the National Park Service began to study the Myakka River for inclusion 

in the National Wild and Scenic Rivers System. The final study recommended 

that the 12 miles of the river in the state park be included as a 

state-administered component of the National Wild and Scenic River 

System, that additional segments of the river be designated as components 

of the national system if state and local efforts could provide permanent 

protection of the corridor, and that a Myakka River commission be formed 

to coordinate conservation efforts. In response to significant local support, 

the Florida legislature designated the 34-mile segment of the river in Sarasota 

County as a Florida Wild and Scenic River in Section 258.501, F.S. 

To date, however, the Myakka River is not a part of the national program. 

In 1990, the Myakka River Coordinating Council, an oversight advisory 

council, produced a management plan that provides an overall resource 

evaluation of the watershed, a river management program, and implementation 

strategies. The recent adoption of the Myakka River Protection Zone 

Agreement, an intergovernmental agreement among the Department, the 

Florida Department of Community Affairs, and Sarasota County, is the 

implementation tool based on the recommendations of the management 

plan. Management efforts within a 220-foot buffer zone landward of 

wetlands bordering the Wild and Scenic portion of the river include more 

stringent development review criteria and performance standards than 

those required of development outside the protection area, the removal of 

exotic plant species, the prohibition of removal of wetland vegetation along 

the river (with minimal exemptions), and other actions. 

Myakka River Basin Land Acquisition Programs. 

Southwest Florida Water Management District Land Acquisition 

Program. The district has acquired nearly 25,000 acres in the Myakka 

River watershed. 

Manatee County Environmental Lands Management and Acquisition 

Committee. In 1992, the Board of County Commissioners created 

the Environmental Lands Management and Acquisition Committee 

(ELMAC), which is charged with the responsibility of identifying environmentally 

sensitive lands for acquisition as well as nonfee simple methods 

of protection. Prior to the formation of ELMAC, Manatee County voters 

passed two referenda in 1984 and 1987 to fund land acquisition in the 

Lake Manatee watershed. Lands purchased by the county are evaluated for


passive recreation consistent with the environmental sensitivity of the particular 

tract. The Duette Park property, purchased to protect the Manatee 

River watershed and the county’s source of potable water, consists of about 

21,149 acres in eastern Manatee County, with small portions of the property 

crossing into some of the northern parts of the Myakka watershed. 

Manatee County does not currently have an ongoing, countywide funding 

program for land acquisition. 

Sarasota County Environmentally Sensitive Lands Acquisition 

Program. The Environmentally Sensitive Lands Acquisition Program 

actively pursues opportunities for acquiring environmentally sensitive lands 

in the county. Land acquisition efforts are frequently carried out in cooperation 

with other public and private agencies (e.g., Conservation and Recreation 

Lands Program, SWFWMD, Save Our Rivers/Preservation 2000 

Program, and the Nature Conservancy). To date the county has acquired 

several tracts adjoining the Myakka River: T. Mabry Carlton, Jr. Memorial 

Reserve (24,000 acres) and Pinelands Reserve, formerly the Walton Tract 

(6,151 acres). The majority of the Pinelands property stretches west away 

from the Myakka River, but part of the conservation area is within the 

watershed and a short stretch touches the river. About 3,179 acres of the 

property are managed for government use (the Central County Solid Waste 

Disposal Complex), and 2,972 acres are managed as conservation areas. 

Charlotte County Environmental Lands Acquisition Advisory 

Council. Essentially all of the large publicly owned tracts of natural lands 

in Charlotte County were purchased by state or federally funded programs. 

In 1991, the Board of County Commissioners established the Environmental 

Lands Acquisition Advisory Council to aid county staff in identifying 

properties suitable for acquisition. The county also established a trust fund 

for the purchase of environmentally sensitive lands but has not acquired 

any land within the Myakka River watershed to date. 

City of North Port Land Acquisitions. As of 1997, the city owned 

about 487 acres in the Myakkahatchee Creek floodplain, called the Myakkahatchee 

Environmental Park. The creek is one of the city’s most important 

natural resources, serving as a potable water supply source, a natural 

drainage way, and a wildlife corridor. Currently, it is generally managed 

for its drainage function. The city continues to assign a high priority to 

the acquisition of properties along the creek that are in the 25-year floodplain 

and to develop and implement management practices that would 

limit development in these areas. The city intends to use innovative 

growth management techniques such as transfers of development rights and 

develop partnerships with public and private parties in order to protect the 

creek and to complete the proposed acquisition program. 

Upper Myakka River Watershed (Flatford Swamp) Land 

Acquisition. The Manasota Basin and SWFWMD Governing Boards 

approved the acquisition of 18,504 acres in this general area. To date, the 

SWFWMD has acquired approximately 2,357 acres using state land acquisition 

funds. 

Nongovernmental Organizations. A number of citizen and private 

organizations are dedicated to protecting and preserving the Myakka River, 

Myakka River State Park, and surrounding areas through environmental


63 

education and volunteer activism. These groups include the Friends of 

the Myakka, Myakka Conservancy, Crowley Museum and Nature Center, 

Audubon Society (Manatee County, Sarasota County, and Southwest 

Florida Chapters), League of Women Voters, Manatee Sarasota Sierra Club, 

Environmental Confederation of Southwest Florida, and Manasota 88. 

Agricultural Best Management Practices 

The Florida Watershed Restoration Act authorizes the Florida Department 

of Agriculture and Consumer Services (DACS) to develop interim 

measures and agricultural best management practices (BMPs). Additional 

authority for agricultural BMPs is provided in legislation on nitrates and 

ground water (Section 576.045, F.S.), the Lake Okeechobee Protection 

Program (Section 373.4595, F.S.), Agricultural Water Conservation (Section 

570.085, F.S.), and Florida Right to Farm Act Amendments (Section 

823.14, F.S.). While BMPs are often adopted by rule, they are voluntary 

if not covered by regulatory programs. If they are adopted by rule and the 

Department verifies their effectiveness, then implementation provides a 

presumption of compliance with water quality standards. 

Over the last several years, DACS has worked with agriculturists, soil 

and water conservation entities, the University of Florida’s Institute of Food 

and Agricultural Sciences (IFAS), and other major interests to improve 

product marketability and operational efficiency by implementing agricultural 

BMPs, while at the same time promoting water quality and water 

conservation objectives. In addition, programs have been established and 

are being developed to create a network of state, local, federal, and private 

sources of funds for developing and implementing BMPs. 

Agricultural BMP practices and programs under way in the Sarasota 

Bay and Peace and Myakka Rivers Basin include the following: 

Facilitating Agricultural Resource Management Systems Program. 

The Facilitating Agricultural Resource Management Systems (FARMS) 

Program is an agricultural BMP cost-share reimbursement partnership program 

between DACS and the SWFWMD. The purpose of the program is 

to increase the efficiency of agricultural water use and reduce water quality 

impacts from area agricultural operations. Currently, the FARMS Program 

has two priority areas due to specific resource concerns. These areas are the 

Shell, Prairie, and Joshua Creek (SPJC) watersheds (Charlotte and DeSoto 

Counties) and the Upper Myakka River watershed (Manatee and Sarasota 

Counties). The FARMS Program has been successfully promoted in these 

two priority areas and has been embraced by the agricultural community 

and associated commodity groups. The proposed FARMS Program expansion, 

which is currently being developed, will significantly increase the 

ability of the program to assist the agricultural community in meeting the 

water conservation goals for the SWUCA, as stated in the SWFWMD’s 

Regional Water Supply Plan and SWUCA Management Plan. 

Existing SPJC program efforts are composed of two main water 

resource initiatives: the back-plugging of deep wells that produce highly 

mineralized water and FARMS alternative irrigation source projects (i.e., 

surface water use and tailwater recovery) to reduce the use of ground water 

and reduce the off-site discharge of poor-quality water. Both initiatives


were created to improve overall water quality in the SPJC watershed, in 

response to water quality impacts to the city of Punta Gorda’s drinking 

water reservoir. The Upper Myakka River initiatives are predominately 

focused on irrigation efficiency and ground water reductions through the 

use of surface water and tailwater recovery projects. 

To date, the FARMS Program has executed BMP demonstration 

projects in both priority watersheds. Contracts with participating growers 

are a minimum of five years, thus allowing for a guarantee that BMPs will 

be maintained and their effectiveness will be monitored. 

Peace River Valley/Manasota Best Management Practices 

Development Process. Similar to the regional initiative that the Indian 

River growers embarked on nearly four years ago, the Peace River Valley 

Citrus Growers Association is spearheading an effort to develop a regional 

BMP manual for citrus growers in Hardee, DeSoto, Sarasota, and Manatee 

Counties, as well as parts of Charlotte County. While this effort is in the 

early stages, the leadership has already formed a Steering Committee and 

four Technical Work Groups. The Steering Committee also has decided 

to use the existing Indian River BMP manual (discussed in the following 

section) as a “template,” given that much of the citrus in southwest 

Florida is grown on flatwoods-type soils similar to the terrain in the Indian 

River Basin. 

Best Management Practices Manuals 

To encourage growers to use BMPs, manuals have been published for 

a number of agricultural industries, including container-grown plants, 

blended fertilizer plants, agrichemical handling and farm equipment maintenance, 

cow/calf operations, aquaculture, citrus, and landscaping. Many 

of these manuals can be downloaded at http://www.dep.state.fl.us/water or 

http://www.floridaagwaterpolicy.com. Manuals for row crops, equine or 

horse farms, and ornamental nurseries are currently being developed. 

The use of a BMP manual alone, however, does not afford a presumption 

of compliance with the Department’s water quality standards. In general, 

qualifying for a presumption of compliance requires that a site-specific 

BMP assessment process be in place, or that the practices being used have 

been proven effective through research and demonstration. 

• Draft Water Quality/Quantity Best Management Practices for 

Florida Vegetable and Agronomic Crops: DACS and IFAS, in 

cooperation with the Department, water management districts, and 

grower groups, have written a draft BMP manual for vegetables and 

agronomic crops in Florida. These crops include potatoes, corn, 

soybeans, peanuts, peppers, sugarcane, tomatoes, cucumbers, and 

various types of squashes, as well as strawberries and cotton. 

The first such initiative for the industry, the manual is 

extremely important because growers statewide will not only have a 

“baseline” set of good standards and practices, but they will also have 

the opportunity to receive a presumption of compliance with state 

water quality standards. Furthermore, the manual will assist DACS


65 

in implementing a future BMP cost-share program, which will facilitate 

the implementation of BMPs. 

The manual focuses on major areas of importance for agronomic 

and vegetable crop producers: pesticide management, conservation 

practices and buffers, erosion control and sediment management, 

water resources management, and seasonal or temporary farming 

operations. It is based on IFAS Extension Service recommendations, 

the U.S. Department of Agriculture’s Natural Resources 

Conservation Service technical information, and other key reference 

documents. 

• Guide for Producing Container Grown Plants: This manual, 

published in 1995 by the Southern Nurserymen’s Association, 

includes irrigation and fertilization BMPs for the container cultivation 

of nursery plants. It was produced through a cooperative effort 

between the University of Florida, Auburn University, Tennessee 

Tech University, and Virginia Tech. Since the manual is not Floridaspecific, 

an effort is currently under way to use the document in 

developing a Florida-specific manual. 

• BMPs for Blended Fertilizer Plants in Florida: The manual for 

blended fertilizer industrial operations, published in October 1997, 

was cooperatively produced by the Florida Fertilizer and Agrichemical 

Association, DACS, and the Department. 

• BMPs for Agrichemical Handling and Farm Equipment Maintenance: 

Recently revised and reprinted, this manual gives producers 

guidance on hazardous materials, proper pesticide handling, and the 

proper disposal of waste products. It was cooperatively produced in 

1998 by DACS, the Department, and several industry associations. 

• Water Quality Best Management Practices for Cow/Calf Operations: 

Many cattle operators statewide have been trained in using 

this manual and are applying BMPs. The Florida Cattlemen’s 

Association and several state, federal, and local agencies developed 

the manual, which was published in 1999. Copies were printed and 

distributed in 2000 using EPA Section 319 grant funds. 

• Water Quality/Quantity BMPs for Indian River Area Citrus 

Groves: Although the regional BMPs in this manual apply to all 

or parts of 7 east coast (Volusia to Martin) counties, other Florida 

flatwoods citrus operations can benefit from the same practices. 

The Indian River Citrus League led a cooperative effort involving 

15 agencies and industry associations in developing these BMPs. 

Beginning in 2000, the BMP manual and guidance booklets were 

published using EPA Section 319 and industry funds. 

• Aquaculture Best Management Practices: As directed by the 1998 

Florida legislature, DACS worked cooperatively with industry, state 

agencies, and the environmental community to develop a comprehensive 

BMP manual for aquaculture. Florida law requires that 

the Department adopt the manual by rule and provides regulatory


exemptions under Chapters 373 and 403, F.S., for growers who 

implement BMPs and are certified by DACS’ Division of Aquaculture. 

The manual, which was printed and distributed in 2000, 

has been adopted by rule. 

• Florida Green Industries Best Management Practices for Protection 

of Water Resources in Florida: This manual provides BMPs 

for professional turfgrass and landscape managers. Published in 

2002, it was developed through a cooperative effort by Florida Green 

Industries (an industry association); the Department; DACS; the 

Florida Department of Community Affairs; and the St. Johns, South 

Florida, and Southwest Florida Water Management Districts.

Chapter 3: Surface Water Quality Assessment 

Scope of the Assessment 

This chapter presents the results of an updated assessment of surface 

water quality in the Sarasota Bay and Peace and Myakka Rivers Basin. 

The primary purpose of the assessment is to determine if waterbodies 

or waterbody segments are to be placed on the Verified List of impaired 

waterbodies. The listing will be in accordance with evaluation thresholds 

and data sufficiency and data quality requirements in the Identification of 

Impaired Surface Waters Rule (IWR) (Rule 62-303, Florida Administrative 

Code [F.A.C.]). The results of the assessment will be used to identify 

waters in the basin for which total maximum daily loads (TMDLs) will be 

developed. 

The chapter describes the planning units in the basin used as a basis 

for the assessment. A section on each planning unit contains a general 

description and summary of key water quality indicators (such as nutrients, 

chlorophyll a, dissolved oxygen [DO], and microbiological parameters). 

Permitted discharges, land uses, ecological status, and water quality 

improvement plans and projects are summarized for each planning unit. 

The discussion notes where applicable surface water quality criteria have 

been exceeded and summarizes the report’s findings in maps, noting 

potentially impaired waterbodies in each planning unit. The chapter also 

contains background information on sources of data and on designated 

use attainment, and explains the state’s integrated water quality assessment 

process. 

While potentially impaired waters and their causative pollutants are 

identified, it is not within the scope of this report to identify discrete 

sources of potential impairments. Information on the sources of impairment 

will be developed in subsequent phases of the watershed management 

cycle, including TMDL development and implementation. 

Appendix A contains a discussion of the legislative and regulatory 

background for TMDL development and implementation. Appendix B 

provides additional information on reasonable assurance. Appendix C 

provides the methodology used to develop the Planning and Verified Lists. 

Appendix D contains the integrated water quality assessment summary 

(Table D.1) and the water quality monitoring stations used in the assessment 

(Table D.2). Appendix E lists permitted wastewater treatment 

facilities, hazardous waste sites, landfills, and brownfields and Appendix F 

lists Level I land use by planning unit. The complete text of the IWR is 

available at http://www.dep.state.fl.us/water/tmdl/docs/amendedIWR.pdf.


Update on Strategic Monitoring and Data- 

Gathering Activities During Phase 2 

During Phase 2 of the watershed management cycle, strategic monitoring 

and data-gathering activities focused first on waters on the 1998 303(d) 

list, followed by waters that were placed on the Planning List through the 

IWR assessment alone. The majority of the strategic monitoring work 

was conducted by the Florida Department of Environmental Protection’s 

(Department’s) Southwest District staff and included both chemical 

and biological monitoring and data upload to STOrage and RETrieval 

(STORET) databases. Data-gathering activities included working with 

environmental monitoring staff in the Southwest Florida Water Management 

District (SWFWMD) and local and county governments to obtain 

applicable monitoring data from their routine monitoring programs and 

special water quality projects in the basin. 

Thirty-nine waterbody segments on the Planning List and the 1998 

303(d) list needed further data to verify impairment. Parameters included 

silver, cadmium, iron, lead, and selenium. Also included were biology 

(based on bioassessments), biological oxygen demand, DO, fecal and total 

coliforms, unionized ammonia, nutrients and their indicators (nitrogen, 

phosphorus, and chlorophyll a), turbidity, and total suspended solids 

(TSS). 

Ninety-four waterbody segments were verified impaired for at least 

1 parameter in the Sarasota Bay and Peace and Myakka Rivers Basin as 

the result of strategic monitoring and data-gathering activities in Phase 2. 

Table D.1 in Appendix D provides the updated impairment status of the 

basin through May 2005. 

Sources of Data 

The assessment of water quality in the Sarasota Bay and Peace and 

Myakka Rivers Basin includes an analysis of quantitative data from various 

sources, some of which are readily available to the public. These sources 

include the EPA’s Legacy and “new” STORET databases, the U.S. Geological 

Survey, and the Florida Department of Health. The STORET databases 

contain water quality data from a number of sources, including the 

Department, water management districts, local governments, and volunteer 

monitoring groups. 

Table 3.1 summarizes the individual data providers who contributed 

to the IWR Database for the Sarasota Bay and Peace and Myakka Rivers 

Basin for the period of record used in this assessment. Figure 3.1 contains 

a bar chart showing the amount of data provided by each source. 

Appendix C contains a detailed description of STORET and the methodology 

used to develop the Planning and Verified Lists, based on the IWR. 

In 2002, the Department created the IWR Database to evaluate data 

in accordance with the methodology prescribed in the Identification of 

IWR (Rule 62-303, F.A.C.). For the Planning List assessment, the data 

evaluation period of record is 10 years, and for the Verified List, 7.5 years.

Figure 3.1: Sources of Data for the Sarasota Bay and Peace and Myakka Rivers Basins


Table C.1 in Appendix C shows the periods of record for the Verified and 

Planning Lists in the first basin rotation cycle. Data collected between 

January 1, 1997, and June 30, 2004, were evaluated to establish the Verified 

List for the Sarasota Bay and Peace and Myakka Rivers Basin (IWR 

Run 17). 

To support listing decisions, the evaluation of water quality in this 

basin also includes qualitative information drawn from data in technical 

reports and documents that are not yet included in the database. Some of 

these sources include historical water quality or ecological information that 

was not uploaded to the database because of its qualitative treatment of 

issues. 

Attainment of Designated Use 

While the designated uses of a given waterbody are established using 

the surface water quality classification system described in Chapter 2, 

it is important to note that the U.S. Environmental Protection Agency 

(EPA) uses slightly different terminology in its description of designated 

uses. Because the Department is required to provide use attainment status 

for both the state’s 305(b) report and the state’s 303(d) list of impaired 

waters, the Department uses EPA terminology when assessing waters for 

use attainment. The water quality evaluations and decision processes that 

are defined in Florida’s IWR for listing impaired waters are based on the 

following designated use attainment categories: 

Aquatic Life Use Support-Based Attainment 

Primary Contact and Recreation Attainment 

Fish and Shellfish Consumption Attainment 

Drinking Water Use Attainment 

Protection of Human Health 

Table 3.2 summarizes the designated uses assigned to Florida’s various 

surface water classes.

Integrated Report Categories and Assessment 

Overview 

The EPA has requested that the states merge their reporting requirements 

under the Clean Water Act for Section 305(b) surface water quality 

reports and Section 303(d) lists of impaired waters into an Integrated Water 

Quality Monitoring and Assessment Report (Wayland, 2001). This Water 

Quality Assessment Report integrates the 303(d) list and the 305(b) report 

for the Sarasota Bay and Peace and Myakka Rivers Basin. 

Following the EPA’s guidance, the Department delineated waterbodies 

or waterbody segments in each of the state’s river basins, assessed them 

for impairment based on individual parameters, and then placed them into 

one of five major assessment categories and subcategories. These categories 

provide information on a waterbody’s status based on water quality, sufficiency 

of data, and the need for TMDL development (Table 3.3). This 

Assessment Report contains a comprehensive evaluation of waterbodies that 

fall into Integrated Report Categories 1 through 5 in the table. 

Because not enough recent data on chemistry, biology, and fish consumption 

advisories have been collected, currently only a few waterbodies 

or waterbody segments statewide fall into Category 1 (attaining all designated 

uses). In particular, fish tissues in many waterbodies statewide have 

not been tested for mercury. Out of 480 waterbodies or waterbody segments 

in the Sarasota Bay and Peace and Myakka Rivers Basin, none are in 

Category 1. 

More waterbodies and segments statewide fall into Category 2 

(attaining some uses but with insufficient data to assess completely) than 

Category 1 (attaining all uses), because monitoring programs can sometimes 

provide sufficient data for partially determining whether a designated 

use in a particular waterbody is attained. A total of 44 waterbody segments 

in the basin fall into Category 2. 

Most waterbodies in the state, however, fall into Category 3 (having 

insufficient data). In the Sarasota Bay and Peace and Myakka Rivers Basin, 

the breakdown of waterbodies or segments in Category 3 is as follows: 

• Category 3a—211 segments for which no data are available to determine 

their water quality status; 

• Category 3b—59 segments with some data but not sufficient data for 

making any determinations; and 

• Category 3c—48 segments that are potentially impaired based on 

the Planning List criteria. 

A number of waters either fail to meet water quality standards for DO 

or show signs of biological stress or nutrient impairment. According to the 

IWR, specific pollutants causing DO exceedances or biological stress, or 

an underlying nutrient imbalance creating an imbalance in flora or fauna, 

must be documented for a waterbody or segment to be listed as impaired. 

Sometimes these conditions cannot be linked to a causative pollutant, and 

sometimes they may reflect natural background conditions. 

Understanding the 

Terms “Pollutant” 

and “Pollution” 

For purposes of the TMDL 

Program, pollutants are 

chemical and biological 

constituents, introduced by 

humans into a waterbody, 

that may result in pollution 

(water quality impairment). 

There are other causes of 

pollution, such as physical 

alteration of a waterbody 

(for example, canals, dams, 

and ditches). However, 

TMDLs are established only 

for impairments caused by 

pollutants (a TMDL quantifies 

how much of a given pollutant 

a waterbody can receive 

and still meet its designated 

uses). 

Waterbodies that are verified 

impaired due to specified 

pollutants, and therefore 

require a TMDL, are listed 

under Category 5 in the Integrated 

Assessment Report; 

waterbodies with water quality 

impairments due to other 

causes, or unknown causes, 

are listed under Category 4c. 

Although TMDLs are not 

established for Category 4c 

waterbodies, these waterbodies 

still may be addressed 

through a watershed management 

program (for 

example, the Kissimmee 

River restoration).

segment, the Department will propose partial delisting for the uses 

attained. Future monitoring will be recommended to determine if 

remaining uses are attained. 

Future monitoring will be recommended to determine if designated 

uses are attained. 

Future monitoring will be recommended to gather sufficient information 

and data to determine if designated uses are attained. 

A waterbody or segment is potentially impaired for one or more 

designated uses. These waters will be prioritized for future monitoring 

to verify use attainment or impaired status. 

A waterbody or segment exceeds Verified List evaluation criteria 

and may be listed as impaired at the end of Phase 2 of the watershed 

management cycle. However, the data have not yet been 

fully evaluated and the waters have not been formally verified as 

impaired. Further monitoring and analysis may be necessary. 

NOTE: This category is applicable only to the Status Report. 

Waters that pass the Verified List criteria at this stage of the process 

are placed in Category 5. 

After the EPA approves a TMDL for the impaired waterbody or 

segment, it will be included in a Basin Management Action Plan 

(B-MAP) to reduce pollutant loading toward attainment of 

designated use(s). 

Pollutant control mechanisms designed to attain applicable 

water quality standards within a reasonable time frame are either 

proposed or in place. 

This category includes waterbodies or segments that are impaired 

because of naturally occurring conditions or pollution. The impairment 

is not caused by specific pollutants. (See sidebar on previous 

page for a discussion of the difference between the terms 

“pollutant” and “pollution.”) 

Waterbodies or segments in this category are impaired for one or 

more designated uses by a pollutant or pollutants. Waters in this 

category are included on the basin-specific Verified List adopted 

by the Department’s Secretary as Florida’s impaired waters list and 

submitted to the EPA as Florida’s 303(d) list of impaired waters at 

the end of Phase 2. 

Note: The descriptions in Table 3.3 are consistent with the EPA’s integrated assessment categories. In the Status 

Reports for Groups 1 through 3 and in the Assessment Reports for Groups 1 through 2 that were previously produced, 

Categories 4b and 4c were reversed. That is, the description of Category 4b was previously listed as Category 4c, and 

the description of Category 4c was listed as Category 4b.


73 

Currently, 24 waterbodies in the basin are designated as being in 

Category 4. This category includes those waterbodies/segments that are 

impaired but do not require a TMDL for 1 of 3 reasons: 

• Category 4a—No segments for which a TMDL has already been 

developed; 

• Category 4b—1 segment for which there is reasonable assurance that 

the designated use of an impaired waterbody will be attained by an 

existing or proposed pollutant control measure; and 

• Category 4c—23 segments for which the impairment is not attributable 

to a pollutant or pollutants, but is due to natural conditions or 

physical/hydrologic alterations to the waterbody. 

Finally, 94 waterbodies in the basin are in Category 5. These impaired 

waterbodies are on the Verified List of impaired waters adopted by the 

Department’s Secretary and will require TMDLs. Chapter 5 of this report 

discusses in detail the waters in this category. 

Planning Units 

The Sarasota Bay and Peace and Myakka Rivers Basin encompasses 

approximately 3,353 square miles and a complex hydrologic system. To 

provide a more detailed geographic basis for identifying and assessing 

water quality improvement activities, the basin was subdivided into smaller 

areas called planning units. A planning unit is either an individual large 

tributary basin or a group of smaller adjacent tributary basins with similar 

characteristics. Planning units help organize information and management 

strategies around prominent watershed characteristics. 

Water quality assessments were conducted for waterbody segments 

within planning units. Each of these smaller, hydrologically-based drainage 

areas within a planning unit is assigned a unique waterbody identification 

number (WBID). Waterbody segments are assessment units (or geographic 

information system polygons) that the Department used to define waterbodies 

when it biennially inventoried and reported on water quality to the 

EPA under Section 305(b) of the federal Clean Water Act. These WBIDs 

are the assessment units identified in the Department’s lists of impaired 

waters submitted to the EPA in reports under Section 303(d) of the Clean 

Water Act. 

The Sarasota Bay and Peace and Myakka Rivers Basin contains six 

planning units: Sarasota Bay, Upper Peace River, Middle Peace River, 

Lower Peace River, Upper Myakka River, and Lower Myakka River. 

Table 3.4 describes these planning units, and Figure 3.2 shows their 

locations and boundaries. The remainder of this chapter provides a general 

description of each planning unit, information on land use and potential 

point sources of pollution, water quality assessments for individual waterbody 

segments, and summaries of ecological issues and watershed quality 

improvement plans and projects.

Assessment by Planning Unit 

• Sarasota Bay Planning Unit 

General Description 

The Sarasota Bay Planning Unit covers about 52 square miles of open 

water and contains 53 segments with WBIDs. It includes some of Florida’s 

most beautiful and productive estuaries, as well as numerous freshwater 

and saltwater wetlands and several tidally influenced coastal streams and 

sloughs. The latter are typically intersected by drainage canals. 

The planning unit extends along Florida’s southwest coast from Anna 

Maria Sound and Palma Sola Bay in the north, to Venice Inlet in the 

south. In the northern portion of the planning unit, a small area drains 

into Palma Sola Bay, and portions of Anna Maria Island drain to Anna 

Maria Sound. Several subbasins drain to the Sarasota Bay Estuary. 

The largest tributary to Sarasota Bay is Phillippi Creek, a highly channelized 

drainage system, which drains 57 square miles. The creek empties 

into Roberts Bay (the northern one) and Little Sarasota Bay. Catfish Creek 

also drains into Little Sarasota Bay. In addition, runoff from other coastal 

regions of the mainland, Siesta Key, and Casey Key contributes to the 

freshwater flow entering Little Sarasota Bay.


75 

Figure 3.2: Locations and Boundaries of Planning Units in the Sarasota Bay and Peace and Myakka Rivers 

Basin


Other major tributaries in the planning unit include South Creek, 

with a watershed of 20 square miles, which empties into Dryman Bay; the 

Bowlees Creek system, which drains 13 square miles; and Whitaker Bayou, 

which drains 8 square miles. Freshwater runoff also enters Sarasota Bay 

from Hudson Bayou, other mainland coastal areas, and the barrier islands 

of Longboat Key and Lido Key. 

At the southern end of the planning unit lie Blackburn Bay, Dona Bay, 

Roberts Bay (the southern one), and Red Lake. Dona Bay and Roberts 

Bay, which become contiguous at their western ends, are small estuaries 

near the city of Venice. Dona Bay receives some discharge from coastal 

regions, but most flow into the estuary is from Shakett Creek/Cow Pen 

Slough, a network of canals and natural stream segments that drains 

approximately 90 square miles. This area is characterized by flat topography 

and undefined drainage ways. Increased seasonal freshwater flow 

and sediment loads transported by this highly modified drainage system 

have contributed to the degradation of water quality and habitat in Dona 

Bay. Roberts Bay is the terminus for Curry Creek. Hatchett Creek, a 

highly channelized system, drains into the Intracoastal Waterway near the 

southern end of Roberts Bay. 

Land use/cover in the planning unit is an amalgam of urban, agricultural, 

and wetland or open-water habitats. In 1995, urbanized areas 

accounted for over one-third of the planning unit’s total area (including 

open water). Coastal areas, including the barrier islands, are almost 

entirely urbanized. Eastern portions of the planning unit contain substantial 

agricultural areas that account for 10 percent of the total acreage. 

Rangeland, pastureland, and row-crop farming dominate agricultural 

activities in the planning unit. Upland forests are patchily distributed, 

although a sizable intact, forested area remains inland from lower 

Sarasota Bay. 

The upper and lower Sarasota Bay watersheds are largely residential. 

Significant tracts of natural systems in the planning unit include a substantial 

amount of upland forests (mostly slash pines and southern slash 

pines) in the lower Sarasota Bay watershed, particularly in the area of 

Oscar Scherer State Park. Large tracts of rangeland also are present in the 

Dona and Roberts Bay watersheds, especially in the headwaters of Cow 

Pen Slough. 

Nonforested freshwater wetlands are found in significant quantities 

in the upper and lower Sarasota Bay watersheds, especially in the upper 

reaches of South Creek. Nonforested wetlands are also common in the 

Dona and Roberts Bay watersheds, and as fragmented parcels in the eastern 

portions of the lower Sarasota Bay watershed. 

In the area of Dona and Roberts Bays, the percentage of residential 

land use is low but growing. Forested and agricultural areas occupy the 

largest areas.


77 

Water Quality Summary 

During the post-World War II period of rapid growth, much environmental 

damage occurred in the planning unit as a result of large-scale 

dredge and fill projects. These projects included the conversion of Bird Key 

into a finger-fill canal community, and the dredging (in the 1960s) of the 

Intracoastal Waterway. The latter may have increased the hydraulic instability 

of Midnight Pass. The movement of the pass resulted in its permitted 

closure and subsequent failed reopening in 1983. 

Sarasota Bay. Tides, winds, physical structure, and freshwater flows 

from inland areas affect water quality in the planning unit’s estuaries, 

including the largest estuary, Sarasota Bay. The flushing and circulation 

patterns created by the interaction of these various factors determine the 

movement and distribution of pollutants, salinity levels, and the kinds of 

biological communities that are present. 

Between 1970 and 1992, the majority of Sarasota Bay became less 

saline, despite the lack of a trend in rainfall in the immediate watershed 

during the same period. The change may be related to increases in the 

amount of impervious surface area that accompanied the increased urbanization 

of the watershed. 

Water quality in some parts of the bay has improved in recent years, 

especially between 1990 and 1992, when the city of Sarasota upgraded its 

wastewater treatment plant and Manatee County’s Southeast Treatment 

Plant and Atlantic Utilities began using deep-well injection. In contrast, 

water quality may be declining in the eastern portion of Sarasota Bay 

between Stevens Point and Bowlees Creek. Water quality in Roberts Bay 

and Palma Sola Bay does not appear to be either increasing or decreasing. 

Chapter 2 discusses these trends in greater detail. 

Water quality in Sarasota Bay is influenced by the amount of watershed 

that drains into different parts of the bay and the size of the bay area 

receiving the drainage. In the northern and central portions of the bay 

(i.e., upper Sarasota Bay), 59 square miles of watershed drain into 45 square 

miles of open water. From Roberts Bay south to Venice Inlet (lower Sarasota 

Bay), 91 square miles of watershed drain into 7 square miles of open 

water. Thus, the ratio of watershed to open water in the northern and 

central parts of Sarasota Bay (upper Sarasota Bay) is 1:3, while in the southern 

part of Sarasota Bay (lower Sarasota Bay), this ratio climbs to 13:4, a 

roughly tenfold increase. 

The bay is characterized by areas with strong tidal influence in and 

near its major passes, and by areas with greatly reduced flushing. Areas of 

reduced flushing can be associated with “dead ends” such as Palma Sola 

Bay, as well as “null zones” for circulation where tidal waves coming in 

from adjacent inlets meet (i.e., Little Sarasota Bay). 

Turnover times for the water in different bay segments vary substantially. 

Turnover times in Anna Maria Sound and the portion of the bay 

adjacent to Big Pass and New Pass average 12 to 13 days. In the area 

off Tidy Island, turnover times average 15 to 16 days, and in Roberts 

Bay, turnover time is estimated at 19 days. In contrast, Palma Sola Bay 

and Little Sarasota Bay have turnover rates of between 32 and 37 days, 

respectively.


Due to the closure of Midnight Pass, turnover times for the water in 

Little Sarasota Bay increased from 14 to 37 days. However, due to the shift 

from two null zones between Venice Inlet and New Pass to one null zone 

in Little Sarasota Bay, turnover time in Roberts Bay decreased from 19 to 

13 days. 

The relatively low turnover time for the waters of Little Sarasota Bay 

(37 days) thus coincides with the much higher watershed-to-open-water 

ratio in this area. From this consideration alone, water quality in Little 

Sarasota Bay is expected to be lower than in the central and northern portions 

of the bay. 

When comparing segments in terms of water clarity, a general pattern 

emerges. Areas closest to flushing passes tend to have the greatest water 

clarity (e.g., Anna Maria Sound and Longboat Pass). Areas farther away 

from the influence of the Gulf of Mexico tend to have the lowest water 

clarity (e.g., Palma Sola Bay and Little Sarasota Bay). However, Roberts 

Bay has poor water clarity, despite its proximity to Big Pass, and the waters 

just west of central Longboat Key have good water clarity, despite being 

located in a null zone for circulation. 

The depth to which seagrasses grow in Sarasota Bay is related to water 

clarity and water quality. A similar relationship probably occurs in Dona 

and Roberts Bays. Activities that reduce nitrogen loads, and thus improve 

water quality, would be expected to improve these important nursery habitats, 

enabling fish populations to grow. 

Seagrass coverage varies throughout the bay. Excluding passes, areal 

coverage ranges from 51 percent of the bay bottom in Anna Maria Sound 

to 6 percent of the bottom in the eastern portion of the bay offshore from 

the city of Sarasota. Baywide, seagrasses cover approximately 32 percent of 

the bay bottom. The depth to which seagrasses grow also varies baywide, 

from less than 50 centimeters below mean sea level (MSL) in Roberts Bay, 

to more than 2 meters (MSL) in Anna Maria Sound. Because water clarity 

is the primary factor controlling the depth to which seagrasses grow in 

Sarasota Bay, improvements in water quality have the potential to increase 

seagrass coverage by allowing seagrasses to grow down into deeper portions 

of the bay that lie farther offshore. 

In past years, the part of Sarasota Bay near the mouth of Whitaker 

Bayou lost a substantial amount of seagrasses, a phenomenon mostly 

attributed to the discharge of secondarily treated wastewater from the city 

of Sarasota. Improvements to the city’s wastewater treatment plant during 

the early 1990s are thought to be responsible for a dramatic improvement 

in water quality in these areas. 

Nitrogen (N), rather than phosphorus (P), seems to be the limiting 

nutrient for algal growth in Sarasota Bay, as N:P ratios (milligrams per 

liter) average less than 6. Nitrogen loads are thought to be approximately 

three times higher than those expected in a pristine, undeveloped watershed. 

Consequently, the elevated nitrogen loads entering Sarasota Bay are 

expected to result in increased abundances of phytoplankton (capable of 

reducing water clarity and shading seagrasses), epiphytic algae (capable 

of shading seagrasses and interfering with gas exchange across seagrass


79 

blades), and macroalgae (capable of shading seagrasses and producing 

recurrent hypoxia in shallow waters). 

Baywide, 55 percent of the nitrogen load to Sarasota Bay comes from 

stormwater runoff. Runoff from residential land uses accounts for 60 percent 

of this amount, or approximately 33 percent of all loads. The high 

level of nitrogen loads coming from residential runoff is attributed to two 

factors: residential land uses account for 42 percent of the watershed and 

event mean concentrations of nitrogen for residential land uses are second 

only to those from row crops, being higher even than those associated with 

runoff from citrus groves. 

Direct atmospheric deposition accounts for about 15 percent of the 

baywide nitrogen load. However, atmospheric deposition is the dominant 

loading source in the northern portions of the bay, associated with the low 

watershed-to-open-water ratio in these areas. Overall, the portions of the 

bay where atmospheric loads are proportionally and quantitatively greatest 

(i.e., Anna Maria Sound and areas just to the south) have the best water 

quality, the greatest water clarity, and the deepest growing seagrasses. As 

important as atmospheric deposition is in terms of loading models, atmospheric 

loads of nitrogen may not have the same biological consequences as 

sources such as stormwater and wastewater (i.e., loading associated with low 

concentrations “applied” over large areas, as opposed to high concentrations 

loaded into more restricted areas). 

Baseflow, that portion of the nitrogen load coming from uncontaminated 

ground water, accounts for 10 percent of baywide loads. 

Although septic tanks only contribute about 10 percent of the baywide 

nitrogen loads, they can be locally important in areas where they are 

the predominant means of sewage disposal. In Roberts Bay, septic tank 

nitrogen loads are estimated at 21 percent of the total. 

Dona Bay and Roberts Bay. In the Dona Bay and Roberts Bay 

system, the largest human influence was the modification of the Cow 

Pen Slough watershed in the 1960s, to reduce flood damage in upstream 

vegetable-producing areas and pastureland. Cow Pen Slough is a large 

contributor of freshwater inflow to the Dona and Roberts Bay system. This 

modification increased the size of the watershed from 68 square miles to 

nearly 90 square miles, creating a very high watershed-to-open-water ratio. 

The historical ratio of 62:1 increased to 89:1. 

Agricultural land uses dominate the Dona and Roberts Bay watershed, 

although the coastal fringe is mostly residential in nature. In the 1970s 

and 1980s, various projects were undertaken to improve water quality in 

Cow Pen Slough. These projects included fencing off Cow Pen Slough 

to prevent cattle from eroding the banks and contaminating the water. 

Perhaps associated with these activities, total nitrogen (TN) concentrations 

in the Dona and Roberts Bay system have declined in recent years and are 

currently lower than the Florida median value. The high total phosphorus 

concentration in the Dona and Roberts Bay system appears to be responsible 

for the strong nitrogen limitation in these waters. 

In addition to their influence on water quality, freshwater influxes from 

the Cow Pen Slough drainage system disrupt the normal circulation and 

salinity distribution patterns throughout the Dona and Roberts Bay system.


The large and rapid fluctuations in salinity that occur throughout the 

Dona and Roberts Bay system are thought to have created a depauperate 

flora and fauna in the outer portions of the bays. 

Not only do fluctuations in salinity make it difficult for the long-term 

survival of seagrasses, but, in addition, during periods of high inflow, 

incoming tides can be kept from entering the bays themselves. This phenomenon 

can reduce the settlement and survival in Dona and Roberts Bays 

of the larval and juvenile stages of animals that spawn in the spring and 

summer. 

Also associated with the large influxes of fresh water during the wet 

season, large rafts of freshwater plants such as Elodea sp. and Hydrilla sp. 

are brought into the outer bays. Once these plants are exposed to the 

higher salinities of the outer portions of the Dona and Roberts Bay system, 

they die. These large quantities of decaying plant material are usually 

found in the same parts of the Dona and Roberts Bay system as the highest 

sediment organic contents and lowest bottom water DO levels. 

Figure 3.3, a composite map of the planning unit, shows waters on the 

1998 303(d) list, the Planning List and Verified List, and potential pollution 

sources. Table 3.5 summarizes the water quality assessment status of 

all waterbody segments in the planning unit. Waterbodies represented by 

these data include the waters of the Sarasota Bay system, extending from 

Anna Maria Sound in the north to Dona Bay in the south, and some of the 

tributaries to the bay system including Bowlees Creek, Phillippi Creek, and 

Clowers Creek. 

The table and figure show that 31 waterbody segments in the planning 

unit are impaired and require a TMDL. The majority of the segments are 

impaired for mercury because of elevated mercury levels in fish tissue. The 

coastal waters of the Gulf of Mexico have fish consumption advisories for a 

number of marine species due to high levels of mercury in fish. Water segments 

are also impaired due to nutrients and coliform bacteria. 

Permitted Discharges and Land Uses 

Point Sources. Figure 3.3 shows permitted wastewater treatment 

facilities, landfills, and delineated ground water contamination areas in 

the Sarasota Bay Planning Unit (see Noteworthy for a definition of point 

sources and discussions of environmental remediation and delineated 

ground water contamination areas). Appendix E lists the basin’s domestic 

and industrial surface discharge facilities, along with their permitted flows, 

by planning unit. It also lists landfills or solid waste facilities, hazardous 

waste sites, and brownfields, by planning unit. 

The Sarasota Bay Planning Unit contains 89 permitted domestic and 

industrial facilities. Seven of them discharge greater than 0.1 million 

gallons per day (mgd) through surface water discharges or by land application 

of the effluent. Two domestic facilities, Gulf Gate and South Gate, 

discharge 1.8 mgd and 1.36 mgd of advanced wastewater treated effluent. 

There is one state-funded hazardous waste cleanup site in the planning 

unit. 

The planning unit contains two Class I solid waste landfills. One is 

active and the other is closed.

Nonpoint Sources. Land use/cover in the watershed is an amalgam 

of urban, agricultural, and wetland or open-water habitats. In 1995, 

urbanized areas accounted for over one-third of the total area (including 

open-water areas). Coastal areas, including the barrier islands, are almost 

entirely urbanized. Eastern portions of the watershed contain substantial 

areas of agricultural lands, which account for 10 percent of the total 

acreage. Agriculture is dominated by range and pastureland and row crop 

farming. Upland forests are patchily distributed, although a sizable intact, 

forested area remains inland from lower Sarasota Bay. These land uses 

can be associated with nonpoint discharges of pollutants and eroded sediments 

(see Noteworthy for a definition of nonpoint sources). Appendix F 

provides summary information on Level I land uses in the basin, by 

planning unit. 

Ecological Summary 

Sarasota Bay. In the Sarasota Bay watershed, freshwater wetlands 

declined by approximately 35 percent between 1975 and 1991, with rates 

of loss in the upper watershed exceeding those for the lower watershed. 

Beyond outright loss and/or destruction, there has also been physical 

damage to existing wetlands (e.g., altered hydrology) and impacts from 

invasive exotic species. 

For the Sarasota Bay area, about 39 percent of it saltwater wetlands 

(both salt marshes and mangroves) were lost between 1950 and 1990. The 

remaining tidal wetlands tend to be smaller and more fragmented than in 

past years. Besides impacts from mangrove pruning, tidal wetlands have 

also been adversely affected by infestations of exotic species, particularly 

Brazilian pepper (Schinus terebinthifolius) and Australian pine (Casuarina 

equisetifolia). 

Seagrasses are found throughout the shallow estuarine waters of the 

planning unit. Increased seagrass coverage in upper Sarasota Bay is mostly 

attributed to 2 major activities: improvements in the disposal and reuse 

practices of Manatee County’s Southwest Regional Wastewater Treatment 

Plant, and upgrades to the city of Sarasota’s wastewater treatment plant. 

For lower Sarasota Bay, 184 acres of the 204-acre increase in coverage 

between 1988 and 1996 (90 percent of the total increase) occurred in Little 

Sarasota Bay; the increase may reflect the system’s recovery from the stresses 

it initially received after the closure of Midnight Pass in 1983. 

For nonvegetated creek and estuarine benthos, data from Sarasota Bay 

suggest that oyster reefs are much more common in the lower bay system 

than in the upper, although oysters can be found in significant quantities 

in the Palma Sola Bay subbasin and also along the mainland shoreline of 

upper Sarasota Bay near Bowlees Creek. The greater coverage of oyster 

reefs in lower Sarasota Bay, compared with upper Sarasota Bay, is probably 

associated with the higher watershed-to-open-water ratio of the lower 

bay, which results in the lower salinity conditions that favor oyster reef 

development. 

In the upper Sarasota Bay watershed, many natural systems have been 

converted to residential and commercial development such as houses, roads, 

shopping centers, and associated land uses. This area has lost the greatest

Water Quality Assessment Report: Sarasota 

Bay and Peace and Myakka Rivers 

Noteworthy 

Information on Point Sources in Planning Units 

Point sources discharging 

pollutants to surface water or 

ground water originate from 

discrete, well-defined areas such 

as a facility discharge from the 

end of a pipe, a disposal well, or 

a wastewater sprayfield. Point 

sources generally fall into two 

major types: domestic wastewater 

sources (which consist of 

sewage from homes, businesses, 

and institutions) and industrial 

wastewater sources (which 

include wastewater, runoff, 

and leachate from industrial or 

commercial storage, handling, 

or processing facilities). Landfills, 

hazardous waste sites, dry 

cleaning solvent cleanup program 

sites, and petroleum facility discharges 

are also considered point 

sources. These sites have the 

potential to leach contaminants 

into ground water and surface 

water. 

Identifying the source of waterbody 

impairment is an important 

part of assessing water quality 

and developing TMDLs. As 

part of this report, information 

is presented on point sources, 

including permitted facilities 

that discharge wastewater and 

landfills. 

Environmental Remediation 

Environmental remediation 

activities cover a broad spectrum 

of cleanup programs. These 

include state-managed hazardous 

waste, dry cleaning, and 

petroleum cleanup programs; 

as well as the federal Superfund 

and Resource Conservation 

and Recovery Act programs. 

These programs are designed 

to remediate ground water and 

soil contamination that pose a 

threat to public health and the 

environment. 

The National Priorities List 

(NPL) is a consolidated list of the 

uncontrolled hazardous waste 

sites that pose the greatest threat 

to public health or the environment. 

Sites are listed on the NPL 

upon the completion of a preliminary 

assessment, site inspection, 

and hazardous ranking system 

evaluation to determine their 

potential for adverse impacts and 

priority for corrective action. The 

EPA Superfund program administers 

the cleanup of NPL sites. 

The Department’s state-funded 

cleanup program administers the 

cleanup of contaminated hazardous 

waste sites when enforcement 

action taken against a 

responsible party is unsuccessful 

or when no responsible party is 

identified. 

Delineated Ground Water Contamination Areas 

The Department’s Delineation 

Program was established 

in response to the discovery of 

ground water contaminated by 

ethylene dibromide, a soil fumigant 

that was historically used 

in 38 Florida counties to control 

nematodes in citrus groves and 

row crops. The program currently 

includes ground water 

contaminated by other pesticides, 

industrial solvents, and 

nutrients. However, the coverage 

of delineated areas in this program 

is not intended to include all 

sources of contaminated ground 

water in Florida. The Delineation 

Program is designed to ensure 

the protection of public health 

when consuming potable ground 

water supplies and to minimize 

the potential for cross-contamination 

of adjacent ground water 

resources. 

The Delineation Program’s 

primary responsibilities are as 

follows: 

• Delineate areas of ground 

water contamination, 

• Implement a water well 

construction permitting/application 

process that requires 

stringent construction 

standards, and 

• Require water testing after 

completion of the well to 

ensure the potable quality of 

the water source. 

Any newly constructed water 

wells in delineated areas, and 

existing water wells found to be 

contaminated, are remediated by 

installing individual water treatment 

systems or by connecting 

the users to public water supply 

systems. 

Nonpoint Sources and Land Uses 

Rainfall generates stormwater 

runoff. As it flows over the land 

and through the ground, runoff 

may carry nonpoint source pollutants 

from many different sources 

to lakes, rivers, and estuaries in a 

watershed, and into ground water 

supplies. Nonpoint sources also 

include atmospheric deposition 

and leaching from agricultural 

lands, urban areas, and unvegetated 

lands. The pollutants in 

runoff often include fertilizers, 

bacteria, metals, sediments, and 

petroleum compounds.


89 

percentage of its original freshwater wetlands, compared with other areas in 

the planning unit, mainly through traditional ditch and drain activities. As 

a result, the storage capacity, water purification, and habitat value of these 

natural systems have declined dramatically. 

The reduced acreage of freshwater wetlands would be expected to alter 

the area’s hydrology, so that tributaries to Sarasota Bay exhibit more of a 

“feast or famine” response to fluctuations in rainfall. That is, draining 

wetlands for development accelerates the delivery of large pulses of fresh 

water to receiving waterbodies, which then decreases the ability of tributary 

systems to “cleanse” these pulses through the processes of uptake and sedimentation. 

In addition, the drainage activity reduces the volume of water 

discharged in the dry season, decreasing the amount of critical low-salinity 

habitat needed for juvenile stages of various species of commercially and 

recreationally valuable finfish and shellfish. 

With most of its natural landscape altered by the rapid and extensive 

development of its watershed, the upper Sarasota Bay watershed has the 

smallest percentage of its total land use in those categories (uplands and 

wetlands) with the greatest habitat value to wildlife. 

In contrast, development pressures in the lower Sarasota Bay watershed 

have not yet resulted in the degree of loss of natural systems that has 

already occurred in the upper basin. The overall impacts are not quite as 

severe as in areas just to the north. Estevez (1992) suggested that the upper 

basin was mostly affected by development pressures that focused on inland 

areas, while the lower Sarasota Bay watershed was mostly affected by development 

pressures that focused on the shorelines and barrier islands. Thus, 

while the upper basin has lost a greater percentage of its freshwater wetlands 

and native uplands, its shoreline has remained mostly in a natural state. 

Conversely, while the lower Sarasota Bay watershed has lost a significant 

amount of its tidal wetlands to development, significant areas of its freshwater 

wetlands and native uplands have persisted, although most of them 

are in a damaged state. 

Dona and Roberts Bays. While much work has been done on the distribution 

of saltmarsh and mangrove communities in upper and lower Sarasota 

Bay, not much detailed information exists for the Dona and Roberts 

Bay watershed. Without question, the biggest alteration to the watershed’s 

natural systems was the development and expansion of the Cow Pen Slough 

drainage system in the 1960s. Because of these activities, the watershed 

increased from 68 square miles to nearly 90 square miles. Much of the 

land use in the watershed is in agricultural and upland forested categories. 

Large influxes of freshwater inflow from the Cow Pen Slough drainage 

system disrupt the normal circulation and salinity distribution patterns 

throughout the Dona and Roberts Bay system; these influxes are associated 

with reduced water quality and the diminished abundance and diversity of 

plants and animals in the outer portions of the system. 

While their distribution is not mapped as well as in upper and lower 

Sarasota Bay, oyster reefs are a common feature in the Dona and Roberts 

Bay system, again probably reflecting the fact that this system has the highest 

watershed-to-open-water ratio in the planning unit.


Water Quality Improvement Plans and Projects 

Waters will not be placed on the Verified List if the Department 

receives reasonable assurance that existing or proposed projects and/or 

programs are expected to result in the attainment of water quality standards 

or consistently improve water quality over time. Chapter 4 and 

Appendix Bcontain additional information on the requirements for 

reasonable assurance. 

For this planning unit, no management plans or projects complying 

with the Department’s guidance for reasonable assurance have been 

provided for the list of impaired waters. 

• Upper Peace River Planning Unit 


The Upper Peace River Planning Unit covers about 615 square miles 

and contains 193 segments with WBIDs. 

Large marshes or lakes form the headwaters of the Peace River, and 

the river itself has wide floodplains and a meandering main channel. The 

system is rainfall driven, with little influence from ground water springs. 

There is tidal flooding along the coast and in the lower reaches of the river. 

Numerous bridges cross the Peace River. Localized upstream flooding and 

damage to the bridges can result if vegetation collects against bridge pilings 

and impedes or halts water flow. 

The Peace Creek subbasin contains a large number of small- to 

medium-size lakes (less than 50 acres to greater than 1,000 acres), with 

more than 50 lakes in the Winter Haven area alone. 

As discussed in Chapter 2, significant declines in stream flow have 

been documented for stations on the main stem of the Peace River, with 

the greatest rates of decline observed in the upper reaches of the river 

near Bartow and Zolfo Springs. Kissengen Springs, which contributed 

approximately 20 mgd to the Upper Peace River, stopped flowing during 

the early 1950s. Sinks have formed in the channel and floodplain of the 

Upper Peace River, and during much of the dry season the river loses flow 

between Bartow and Fort Meade. 

Long-term rainfall deficits have clearly played a major role in the 

reduced flows, but drawdowns of the potentiometric surface of the Floridan 

aquifer in the planning unit due to ground water use are also a major 

factor. Extensive historical phosphate mining affected the region’s hydrology. 

Water control structures have been constructed on the outlets of some 

lakes that form the headwaters of the Peace River drainage system. 

Reduced flows have affected the water quality and biology of the Peace 

River system. Elevated loadings of nitrogen and phosphorus, which stimulate 

excessive growth of aquatic plants and drive the process of cultural 

eutrophication, have severely degraded water quality in some waterbodies 

in the planning unit. A number of surface waters exhibit hypereutrophic 

water quality conditions year-round in response to these loadings. 

The majority of the watershed is subject to relatively little urbanization 

over the next 20 years, considering the total population growth projected 

for the area, the rural-agricultural nature of the upper and central counties


91 

(Polk, Hardee, and DeSoto) that make up the majority of the basin, existing 

and proposed phosphate mining, and the less intensive land uses such 

as ecotourism and storage facilities that support the Tampa and Orlando 

markets. 

Phosphate Mining. Phosphate has been a major economic force in 

the Peace River watershed since the discovery of phosphate pebble in the 

Peace River in the 1880s. In Florida’s “phosphate district,” which includes 

the Peace, Alafia, Little Manatee, and Manatee River watersheds, approximately 

180,000 acres have been mined. 

Phosphate ore is strip-mined through the use of draglines. Historically, 

the phosphate ore matrix was 15 to 35 feet thick and was overlain by a thin 

(5 to 25 feet) layer of overburden. In present-day mining, the phosphate 

matrix is typically about 8 feet thick and is located beneath approximately 

30 feet of overburden. The overburden is removed and stockpiled, and 

then the ore is removed, leaving high, steep piles of overburden soil and 

phosphate pits that fill with water. 

Since 1975, state regulations have required phosphate mining companies 

to reclaim land that is mined. Much of the mined land in the Peace 

River watershed has been reclaimed for pasture, other agricultural uses, 

residential and industrial development, and “land and lakes” areas suitable 

for residential or recreational development. 

Currently, any wetland disturbances must be mitigated. For every acre 

of wetlands disturbed, 1 to 3 acres of wetlands must be enhanced, created, 

or purchased for preservation to offset the disturbance. Floodplain regulations 

differ by county, but typically the 25-year floodplain is always protected 

from mining. 

Approximately 80,000 acres in the planning unit were mined for 

phosphate before mandatory reclamation was required. Approximately 

50,000 acres of these “nonmandatory lands” were deemed eligible for 

nonmandatory (also known as Old Lands) funding by the Zellars-Williams 

report, the guiding document for the nonmandatory program. Of these, 

the program has funded 25,000 acres, and reclamation has been completed 

on 10,000 acres. The remainder is in some stage of reclamation, which can 

require up to 10 years per parcel. 

Clay-settling areas cover some 100,000 acres of the watershed. It takes 

several years for these areas to become sufficiently dewatered to reclaim. 


Potential water quality degradation from past and anticipated future 

phosphate mining activities, industrial and domestic point source pollution 

from existing developments, and uncontrolled nonpoint source runoff from 

agricultural activities on the Peace River are of major concern. Adverse 

impacts from these land uses may include changes in natural surface water 

hydrology, the degradation of regional surface water quality, decreased 

wildlife habitat, or the loss of natural vegetation. 

The main stem of the Peace River has experienced significant water 

quality degradation for many years. In earlier decades, large point source 

discharges and periodic mining-related spills affected water quality. 

Although impacts from these factors have been greatly reduced, the Peace


River still periodically experiences large algal blooms and depressed DO 

concentrations. These degraded water quality conditions appear to be 

seriously affecting fish and other biological resources in the river. 

Furthermore, periodic blooms of cyanobacteria (blue-green algae) 

affect the use of the river downstream for potable water supplies. Various 

factors may influence the occurrence of algal blooms and other water 

quality problems in the river, including periodic discharges of algal-rich 

water from Lake Hancock, downstream nutrient loading, and reduced 

stream flow. 

As with the river reach above Bartow, nonpoint source runoff and 

permitted industrial discharges are the largest loading sources for the 

Bartow to Zolfo Springs segment of the river, contributing 64 percent and 

35 percent of the estimated nitrogen load, 18 percent and 81 percent of the 

estimated phosphorus load, and 70 percent and 30 percent of the estimated 

load of TSS, respectively, from 1985 to 1991. Rangeland, mining, urban, 

and agricultural land uses contribute large proportions of the anthropogenic 

nonpoint source loadings in this portion of the watershed, while 

phosphate mining and processing facilities make up the bulk of the industrial 

point source discharges. 

Tributary streams of the Peace River exhibit a wide range of water 

quality conditions. Many streams in the upper portions of the watershed 

were historically affected by phosphate mining and point source discharges. 

In recent years, water quality has improved in some tributaries due to 

improvements in mining practices, waste treatment processes, and alternate 

means of waste disposal. Nutrient concentrations in other tributaries in 

the watershed (e.g., Horse and Joshua Creeks), however, have increased as a 

result of rising nonpoint source pollution. 

Cultural eutrophication is the most serious water quality problem in 

the Peace Creek subbasin, where nutrient loading to lakes is attributed to 

a combination of point source discharges of domestic wastewater (treated 

sewage effluent) and urban stormwater runoff. 

Sediments dated to about 1860 indicate that the Winter Haven Chain 

of Lakes was historically in the mesotrophic to eutrophic range (moderately 

to slightly nutrient enriched), with a lack of blue-green algae blooms during 

the summer. Discharges from two significant domestic point sources (the 

city of Lake Alfred and city of Winter Haven wastewater treatment plants) 

were recently removed from Lakes Haines and Conine in the northern 

Winter Haven Chain of Lakes. 

While no direct point source discharges remain in this chain of lakes, 

water quality degradation persists as a result of historical discharges. In 

addition, much of the urbanization that has occurred preceded stormwater 

treatment regulations. As a result, much of the stormwater entering the 

lakes lacks adequate treatment. The original SWIM plan for the Winter 

Haven Chain of Lakes identified stormwater treatment as a high priority, 

and the updated plan reaffirms that position. 

A number of other lakes in the Peace River watershed also currently 

violate certain state water quality criteria, fail to meet their designated 

uses, or are noticeably degraded from their historical condition. Most 

lake water quality problems are attributable primarily to excessive nutrient


93 

enrichment. Characteristic of cultural eutrophication is a marked increase 

in the frequency and severity of cyanobacteria blooms (blue-green algae). 

Blooms of cyanobacteria and algae, aside from causing aesthetic problems, 

can generate health concerns, cause fish kills, increase the rate of sediment 

accumulation in a lake, and affect downstream water quality. 

Lake Hancock, one of the most polluted lakes in Florida, has Trophic 

State Index values that are routinely among the highest recorded in the 

state. Point source discharges to tributaries of the lake and agricultural 

runoff have all contributed to hypereutrophic conditions. Although external 

nutrient loading has been greatly reduced in recent years, thick layers 

of flocculent organic sediments have accumulated in the lake, resulting in 

high rates of internal nutrient recycling. 

While pesticide (insecticide and herbicide) concentrations are not 

intensively monitored in the planning unit, a recent study by the National 

Oceanic and Atmospheric Administration suggests that surface water quality 

in the region may be at risk due to high per-acre application rates of 

several relatively hazardous compounds. Among herbicides, the Charlotte 

Harbor watershed (including the Peace and Myakka watersheds) has the 

highest estimated 2,4-D use (more than 330,000 pounds/year) of Gulf 

of Mexico estuaries, with the majority of the material applied to pasture 

and rangelands. Among insecticides, endosulfan (applied to tomatoes) 

and chlorpyrifos (applied to citrus) make the largest contributions to 

the elevated risk ranking calculated for Charlotte Harbor. Much of this 

agricultural chemical use presumably occurs in the Peace River watershed, 

which contains a large proportion (about 85 percent) of the nonrangeland 

agricultural acreage in the Charlotte Harbor Basin. 





these data include the Winter Haven Chain of Lakes and the lakes within 

the Lake Hancock/Saddle Creek watershed, as well as Saddle Creek, the 

Peace Creek Drainage Canal, and the Upper Peace River segment.

The Upper Peace River Planning Unit contains 178 permitted domestic

There are two hazardous waste sites in the planning unit and both are 

state-funded cleanup sites.

The planning unit contains three Class I solid waste landfills. One 

is active, one is inactive, and one is closed. There are three Class II solid 

waste landfills that are closed and four Class III solid waste landfills, of 

which three are active and one is closed. There are also three construction 

and debris (C&D) landfills. One is active, one is inactive, and one is 

closed. 

Nonpoint Sources. Agriculture, phosphate mining, and urban development, 

which encompass 29 percent, 22 percent, and 19 percent of the 

land area, respectively, are the major land uses in the Upper Peace River 

Planning Unit. The remaining undeveloped land consists of open water 

(12 percent), wetlands (10 percent), and upland forests (4 percent). These 

land uses can be associated with nonpoint discharges of pollutants and 

eroded sediments. Appendix F provides summary information on Level I 

land uses in the basin, by planning unit. 


The high rate of land use conversion in the watershed has resulted in a 

correspondingly high rate of degradation to natural systems and widespread 

habitat destruction and fragmentation. Extensive modifications to surface 

hydrology, including the channelization or severance of natural drainage 

features that historically discharged to the Peace River, have reduced water 

quantity and quality in the river and its tributaries. As a result, aquatic 

communities have been severely affected. Fish populations in the upper 

reaches of the river are characterized by low biomass and diversity, with 

species compositions dominated by pollution-tolerant species (gar, bowfin) 

or exotic species (tilapia). The impacts to fish and invertebrate populations 

are manifested upwards in the food web, including wildlife associated with 

the upper river. 

Impacts to terrestrial systems have been equally severe. Much of the 

remaining natural land cover occurs as small, disjunct fragments scattered 

across a highly modified landscape, or as narrow threads of floodplain 

forest lining the creeks and other small drainages that discharge to the 

Peace River. The well-drained scrub and sandhill upland associations have

108 


been most severely affected. The natural incidence of these associations 

in the watershed’s low, flat terrain was quite low historically, and their 

attractiveness for development has made them particularly susceptible to 

large-scale alteration. Pine flatwoods and herbaceous wetlands, the 2 most 

prevalent natural communities in terms of areal extent, have also been 

severely affected, with only 30 percent and 42 percent of their historical 

coverage remaining, respectively. 

Wildlife population dynamics are affected on reclaimed phosphate 

lands, especially on large expanses where adjacent populations are missing 

and recolonization may take many years. Mining and reclamation can 

interrupt the life cycles of species that depend on the habitat being mined. 

In the case of upland species that depend on wetlands at some time during 

their life cycles (e.g., the gopher frog), mining of wetlands alone can interrupt 

those life cycles, even if the upland is left intact. 

The wetlands created by phosphate mining often function very well 

hydrologically and are used heavily by certain types of wildlife, especially 

wading birds. However, while nonforested wetlands and their vegetative 

assemblages do not take long to mature, the reclamation of forested 

uplands takes much longer. Since restoring forested habitat typically 

involves planting seedlings, it takes decades for a reclaimed pine flatwood 

to mature. The same holds true for other forested upland habitats. 

Nonmandatory reclamation lands, along with lands reclaimed as 

habitat and native range that are not subject to development, and preserved 

lands throughout the Peace River watershed, form the Integrated Habitat 

Network (IHN), a concept developed by the Department, the Florida Fish 

and Wildlife Conservation Commission, and the phosphate industry. The 

IHN is a network of public and private lands that serve as wildlife corridors. 

Much of this network consists of preserved riverine corridors in 

the Peace, Alafia, and Little Manatee watersheds. The IHN also includes 

mined land reclaimed as wildlife habitat and native range, as well as naturally 

revegetated, unreclaimed nonmandatory lands. 

As mined lands are reclaimed to natural landcover types and permanently 

protected through easements or other means, they will be incorporated 

into the IHN. Recent efforts have focused on reconnecting the 

historical connections of mined tributaries. These efforts will likely be 

significant in reconnecting reclaimed tributary subbasins to the main stem 

of the river corridor and providing movement corridors for wildlife, as well 

as source areas for recolonization. Implementation of the IHN is a key 

element in the recovery of the Peace River watershed. 

Unfortunately, very few natural areas of substantial size in the Peace 

River watershed have been protected through public acquisition. Conservation 

lands in the watershed total 54,696 acres. In addition, the disjunct 

arrangement of these sites, in combination with their relatively small size 

and isolation from other protected areas, limits their ability to provide 

high-quality “core” habitat for wildlife. Hardee and DeSoto Counties, 

which lie almost wholly within the watershed and account for over half of 

its total area, are the 2 Florida counties with the lowest percentage of their 

total land area in protected conservation status. Although Polk County 

fares considerably better in this measure of natural system protection, the


109 

vast majority of conservation lands in Polk County lies outside the Peace 

River watershed. 

Currently, the Babcock/Cecil Webb Wildlife Management Area 

in Charlotte County (67,426 acres), Highlands Hammock State Park 

(5,000 acres), Tenoroc State Recreation Area (9,500 acres), and the 

SWFWMD-owned R.V. Griffin Reserve project (5,850 acres) are the only 

large blocks of public land in the watershed where protection of wildlife 

habitat values is a fundamental management goal. The Babcock/Cecil 

Webb Wildlife Management Area lies at the extreme southern end of the 

watershed, and only about half (35,000 acres) of the site is within the 

watershed. The Tenoroc tract consists of reclaimed mine land managed 

primarily to accommodate recreational usage; it lies in a matrix of developed 

areas and other mined lands at the northern end of the watershed. 

The Saddle Creek Strip Mines and Saddle Creek Park sites also consist of 

reclaimed phosphate mine land. 

Management and use of the R.V. Griffin Reserve emphasizes water 

supply functions associated with the Peace River Water Treatment Plant. 

In addition, the R.V. Griffin Reserve and Highlands Hammock State 

Park lie on opposing boundaries of the watershed (western and eastern, 

respectively). The R.V. Griffin Reserve and Saddle Blanket Lakes Preserve 

straddle the watershed boundary and are located partially in adjoining 

watersheds. The Paynes Creek State Historical Site is relatively small and 

is managed to preserve a site of historical and cultural significance, and to 

preserve natural values over the long term. 

Although a number of public land acquisition projects are proposed for 

the watershed, and these could expand core wildlife habitat significantly, 

the addition of core habitat alone will be insufficient. The preservation of 

a diverse and stable complement of the wildlife species native to the Peace 

River watershed will depend on preserving adequate habitat inside the 

watershed, maintaining linkages between such sites whenever possible, and 

linking such areas to large blocks of core habitat lying outside the watershed. 

Corridors protected by conservation easements and/or consisting of 

agricultural land may, in some cases, be adequate to maintain functional 

connections. 

Several large blocks of protected lands outside the watershed serve as 

core areas of wildlife habitat of statewide significance. Core areas proximate 

to the Peace River watershed include the following: 

• The Myakka River State Park complex of lands, consisting of the 

Myakka River State Park (28,800 acres), SWFWMD’s MacArthur 

Tract (8,200 acres), and the T. Mabry Carlton Memorial Reserve 

(31,600 acres); 

• The Avon Park Bombing Range area, comprising the federally owned 

Avon Park Bombing Range (100,000 acres) and the state-owned 

Lake Wales Ridge State Forest (16,675 acres); 

• The state-owned Babcock/Cecil Webb Wildlife Management Area 

(67,000 acres) (which actually straddles the watershed boundary); 

and

110 


• The Green Swamp, which includes contiguous public lands totaling 

approximately 150,000 acres. 

Acquisition projects that have been approved by the SWFWMD 

(Myakkahatchee Creek and Myakka River/Charlotte Harbor) may ultimately 

expand the Myakka River State Park complex to approximately 

105,000 acres. Protected lands in the Green Swamp may also be expanded. 

A recent SWFWMD purchase provides significant protection of 

lands in the Peace River floodplain. The 2,046-acre tract is a portion of 

the Lower Peace River Save Our Rivers Project and protects a mixture of 

floodplain swamp, marsh, and an adjoining buffer of pine flatwoods at the 

downstream end of the river. 

A number of public acquisition projects have been proposed for the 

watershed, including the SWFWMD’s Peace River Corridor and Upper 

Peace River Corridor projects (a total of approximately 57,500 acres), and 

other projects are under review for possible acquisition (Charlie Creek, 

Horse Creek, and Peace Creek system). 

Some existing conservation areas may be expanded through the 

acquisition of adjoining natural lands. Lands lying outside the watershed 

but adjacent to the R.V. Griffin Reserve (Toledo Blade project) could, for 

example, expand the total size of this core habitat area by over 9,000 acres. 

The long-term habitat value of the R.V. Griffin Reserve would be enhanced 

significantly through such an expansion. 

Exotic Species Control. Terrestrial species of particular concern in 

the Peace River watershed include skunk vine, climbing fern, tropical soda 

apple, and cogon grass. SWFWMD has budgeted funds for a two-year 

biological control feasibility study of skunk vine in an attempt to develop 

effective control methods, and is developing best management practices to 

guide ongoing control efforts for this species.

• Middle Peace River Planning Unit 


The Middle Peace River Planning Unit covers about 1,155 square miles 


See the section on the Upper Peace River Planning Unit for a 

detailed description of the watershed. 

Much of the land surrounding the Peace River in Hardee County contains 

viable phosphate resources and is affected by mining interests. These


111 

areas are designated as mining overlay districts. As phosphate reserves 

in Polk County are depleted, the potential for mining of those lands in 

Hardee County’s overlay district increases. 



detailed description of water quality issues. 





these data include segments of the Peace River and major tributaries including 

Payne Creek, Charlie Creek, Joshua Creek, and Horse Creek. 

The table and figure show that two waterbody segments in the planning 

unit are impaired and require a TMDL. A mainstem of the Peace 

River is impaired for mercury because elevated levels in Largemouth Bass 

exceeded the IWR threshold for listing and Chilton Lake is impaired for 

nutrients. 




Middle Peace River Planning Unit. Appendix E lists the basin’s domestic 




The Middle Peace River Planning Unit contains 67 permitted domestic 

and industrial facilities. Two facilities discharge greater than 0.1 mgd 

through surface water discharges or by land application of the effluent 

(William Tyson WWTP, 2 mgd, and the city of Wauchula WWTP, 

1 mgd). 

There are no hazardous waste cleanup sites in the planning unit. 

The planning unit contains five Class I solid waste landfills. Two are 

active, two are inactive, and one is closed. There are three Class II solid 

waste landfills that are closed. Of the two C&D landfills, one is inactive 

and one is closed. 

Nonpoint Sources. Agriculture, which encompasses 52 percent 

(598 square miles) of the land area, is the major land use in the Middle 

Peace River Planning Unit. Wetlands, upland forests, and rangeland 

encompass 17 percent, 11 percent, and 7 percent of the land area, respectively. 

Phosphate mining and urban development make up 8 percent and 

4 percent of the remaining land, respectively. These land uses can be 

associated with nonpoint discharges of pollutants and eroded sediments. 

Appendix F provides summary information on Level I land uses in the 

basin, by planning unit.

The Lower Peace River Planning Unit covers about 554 square miles 



detailed description of the watershed. 

Population centers along the lower reaches of the Peace River include 

Port Charlotte and Punta Gorda. 



detailed description of water quality issues. 

Shell Creek and its tributary, Prairie Creek, are among the least 

impacted streams in the Peace River watershed. Because of its relatively 

large drainage area and flow, the Shell Creek system has special hydrologic 

and ecological importance. Shell Creek supplies about one-fourth of the 

total freshwater flow from the Peace River watershed to its receiving estuary. 

Nutrient concentrations in Shell Creek are low compared with other 

tributaries in the watershed, and flows from Shell Creek are important 

for maintaining water quality and the health of the Lower Peace River/ 

Charlotte Harbor estuarine system. The creek also provides potable water 

supplies for the city of Punta Gorda. 

Although it is generally considered to have fair to good water quality, 

the estuary associated with the Lower Peace River and upper Charlotte 

Harbor periodically experiences significant water quality problems. Low 

concentrations of DO (hypoxia) are common in portions of the estuary 

during the summer rainy season. Nutrient-driven phytoplankton blooms 

also occur seasonally in the tidal reaches of the river and in upper Charlotte 

Harbor, and they periodically cause chlorophyll a concentrations to reach 

levels that would be characterized as hypereutrophic in some estuarine classification 

systems. 

Factors contributing to these conditions are complex. One study found 

increasing trends for inorganic nitrogen in low-salinity waters and TN 

concentrations in high-salinity waters. Combined with increasing nitrogen 

trends observed in several tributaries of the estuary, this may indicate 

cultural eutrophication. To date, studies on the relationships of nutrient 

loading to water quality problems in the estuary have proven inconclusive. 





these data include mainstem segments of the Peace River and tributaries 

including Shell Creek and Thornton Branch. 


unit are impaired and require a TMDL. The most common parameters of 

concern are nutrients, DO, and mercury in fish. The estuarine portions of 

the Peace River are listed for mercury due to the fish consumption advisories 

for a number of marine species in the Gulf of Mexico coastal waters.

detailed description of ecological issues. 

Shell and Prairie Creeks, along with the Shell Creek Reservoir, support 

excessive growths of water hyacinth and water lettuce. These species are 

also prevalent in the river channel. 











• Upper Myakka River Planning Unit 


The Upper Myakka River Planning Unit covers about 211 square miles 


The Myakka River originates in marshes near Myakka Head, and from 

there flows nearly 66 miles southwest to the Charlotte Harbor Estuary. In 

the upper reaches of the river near Myakka Head in Manatee County, the 

river consists of a very narrow channel during the dry season and an undefined 

channel during the wet season. 

In its meandering course, the Myakka River changes its character as it 

increases in size and passes through several natural lakes and swamps; different 

vegetative communities dominate its banks. In the Upper Myakka 

River planning unit, mesic flatwoods are the dominant habitat type. The 

wetlands adjacent to the river are mixed hardwoods dominated by bays, 

oaks, and pop ash with a fern understory. 

Major features in the planning unit include the following: 

• Flatford Swamp. Wingate Creek joins the Myakka River at River 

Mile 60, and Flatford Swamp lies below River Mile 59 and north 

of State Road (S.R.) 70, near Myakka City. The swamp is formed 

by the convergence of eight creeks (Johnson, Wingate, Taylor, 

Young’s, Coker, Long, Maple, and Ogleby). The first of four large 

topographic depressional areas in the watershed, the swamp is a 

regionally important and unique surface water feature; its importance 

extends to Charlotte Harbor itself. The swamp moderates 

flood conditions, cleanses water through its wetlands, and contains 

valuable habitat. 

Immediately below Flatford Swamp, the river runs through 

pop ash swamp and marsh habitats. This vegetation remains the 

dominant association for the remainder of the river to the estuarine

126 


portions associated with Charlotte Harbor, which contains saltmarsh 

habitat. 

• Ogleby Creek. Ogleby Creek is the largest stream entering the 

Myakka River above Myakka Lake. Its watershed includes the 

community of Verna. A large marsh south of Verna is a result of the 

confluence of Ogleby Creek and the Myakka River. This wetland 

is two miles wide at its broadest east-to-west point. Southeast of the 

marsh is Myakka City, which is built on level to gently sloping land 

with slow surface drainage and very slow internal drainage. Land use 

in the segment of the river south of Myakka City is primarily agricultural 

and rural residential. 

• Owen Creek. Owen Creek enters the Myakka River just east of 

Myakka City. The creek originates in a marsh that stretches between 

Manatee and Hardee Counties. The eastern portion of the marsh 

drains into Horse Creek, which feeds into the Peace River, and the 

western portion flows into Owen Creek. From Myakka City to 

the Tatum Sawgrass area, the river drops 24 feet in elevation over 

4 1/2 miles. The floodplain averages a half-mile wide, and the riverbed 

begins to meander. 

• Tatum Sawgrass Area. At River Mile 43, just above Myakka River 

State Park, the river channel splits into Clay Gully and the Myakka 

River. Both watercourses run into Upper Myakka Lake. About 

5 miles southwest of Myakka City, before entering the state park, 

the Myakka River traverses about 0.5 miles of the lower Tatum 

Sawgrass Area, a large depression of about 14 square miles. This 

4,300-acre marsh can store the equivalent of 1.8 inches of rain over 

the entire upper watershed (235 square miles). It serves as a valuable 

water resource, moderating the downstream effects of flooding and 

drought. A series of dikes was constructed around 1974 to divert 

water away from the marsh to allow its conversion to agricultural 

land. These dikes have reduced the water storage capacity of the 

marsh and increased flood stages downstream. 

At Myakka City, some channelization and alteration of the river 

have occurred. Below Myakka City, at River Mile 52, there is a 

transition from marsh and hardwood swamp to cabbage palm, live 

oak, and laurel oak hammock. 

The upper watershed of the Myakka River is generally undeveloped, 

except for ranching and other agricultural activities. Agriculture is feasible 

because of drainage projects, such as those in the Ogleby and Owen Creek 

watersheds, that significantly change surface runoff patterns. Also, diking 

and ditching activities in the Tatum Sawgrass area prevent the river water 

from slowly filtering through and dropping its nutrient load in the marsh. 

Most environmental issues related to the watershed stem from human 

impacts. Portions of the watershed have undergone significant alteration 

from forested uplands, wetlands, and sloughs to a mixture of urban, agricultural, 

mining, and relict intact biological communities. This pattern of


127 

land conversions and its requisite infrastructure elements (e.g., roads, utility 

systems, and landfills) will continue to shape conditions in the Myakka 

River watershed’s remaining natural systems. 


During the past century, a variety of human activities—including 

phosphate mining, citrus and row crop production, cattle production, 

and urban and suburban development—has produced increased loadings 

of nutrients and other pollutants to surface waterbodies in the Myakka 

watershed. These impacts have been less severe than in other regional river 

systems, such as the Peace River. Water quality in the Myakka watershed 

is generally good overall, with most tributary streams having fair to 

good water quality. Three areas have fair water quality, including Myakkahatchee 

Creek/Big Slough Canal, which is a Class I waterbody and a 

potable water source for the city of North Port. 

Water quality in the river during high flows is good, but during lowflow 

periods it is poor due to the contributions of ground water and runoff 

from agricultural operations. Future increases in nitrogen and phosphorus 

loadings, which stimulate the growth of aquatic plants and drive the process 

of cultural eutrophication in surface waterbodies, appear to represent 

the greatest potential threat to water quality in the Myakka River system, 

including the estuarine portion of the lower river. 

Water quality monitoring results show elevated specific conductance 

and major ion (sulfate and calcium) values in the major tributaries to 

Flatford Swamp, compared with ambient surface water systems. Elevated 

values for these constituents within a surface water system are traditional 

markers of irrigation water from deeper, more mineralized aquifers. 

Elevated levels of certain pesticide and herbicide compounds in surface 

waters in the monitoring area also suggest that the source may be attributed 

to runoff from the irrigation of agricultural areas surrounding the Flatford 

Swamp watershed. The most commonly detected pesticides were endosulfan 

sulfate (an insecticide), bromacil (a herbicide), and diazinon (an insecticide). 

No pesticides or herbicide compounds were detected at downstream 

monitoring stations, suggesting that flows leaving Flatford Swamp are not 

affecting the Myakka River. 





these data include the mainstem of the Upper Myakka River and the Owen 

Creek and Howard Creek tributaries. 

The table and figure show that three waterbody segments in the planning 

unit are impaired and require a TMDL. The parameters of concern 

are coliform bacteria in the Upper Myakka River and Owen Creek and DO 

in the upper river and Howard Creek.

(104 square miles) of the land area, is the major land use in the Upper 

Myakka River Planning Unit. Urban development comprises less than 

6 percent of the land. The remaining undeveloped land consists of wetlands 

(18 percent) and upland forests (11 percent). These land uses can be 

associated with nonpoint discharges of pollutants and eroded sediments. 

Appendix F provides summary information on general land uses in the 

basin, by planning unit. 


In the mid 1990s, the SWFWMD began receiving inquiries about 

potentially abnormal numbers of dead trees in Flatford Swamp and adjacent 

areas. During numerous site visits, district staff subsequently observed 

a relatively high degree of tree mortality. The last survey conducted for 

the SWFWMD in 1998 documented 2,571 acres of dead and dying trees. 

Similar patterns were simultaneously reported in other portions of the 

Myakka River watershed south of S.R. 70. The Crowley Nature Preserve, 

immediately north of S.R. 780 on the Myakka River in Sarasota County, 

and Myakka River State Park were also areas of particular concern. 

The evidence indicates that the primary cause of the tree die-off and 

other changes in the Upper Myakka watershed is hydrologic stress related 

to either higher seasonal high water elevations, longer seasonal hydroperiods, 

or both. A water quality analysis indicates increased base flow contributions 

from ground water used for agricultural irrigation. Since elevated 

ground water levels prevent or reduce natural dry season water levels, 

upland trees and the swamp have remained too wet for too long and the 

system is changing. 






Appendix Bcontain additional information on the requirements for reasonable 

assurance.

• Lower Myakka River Planning Unit 


The Lower Myakka River Planning Unit covers about 387 square miles 


Major features in the planning unit include the following: 

• Upper Myakka Lake. Upper Myakka Lake, a limestone sinkhole 

feature of 875 acres, ranges in depth from 3 to 6 feet. Above the 

lake, the hydraulic gradient of the Myakka River is always greater 

than 1 foot per mile. Beginning at the lake, a long, flat plain with 

a gradient of less than a half-foot per mile stretches to the mouth of 

the river at Charlotte Harbor. 

Historically, water left the lake through two channels at the 

southwest end of the lake. Shep’s Island, a high ridge, splits the 

water into two channels—the present river channel and Vanderipe 

Slough. The two channels converged again above Lower Myakka 

Lake. The land around the lake was used for grazing cattle and 

horses before the creation of Myakka River State Park. 

When the park was created, an earthen dam was built across 

the branch of the river leading to Vanderipe Slough. The dam was 

constructed by the Civilian Conservation Corps around 1941. The 

slough then became a seasonally flooded marsh. Later, a concrete 

spillway was constructed across the river channel at the lake’s outlet, 

stabilizing the lake level at six feet to provide boating and fishing 

throughout the year. In the 1970s, culverts were installed to allow 

water to flow around the concrete weir. 

• Lower Myakka Lake. Downriver from Upper Myakka Lake, 

the river flows through a large marsh known as Big Flats. Below 

S.R. 72, the river enters the Myakka River State Park Wilderness 

Preserve. At this point, the hammock closes in on the river channel 

for a short reach before again opening into marshes at the northern 

end of Lower Myakka Lake. Approximately one-half mile below the 

state park boundary, at River Mile 28, a private dam, known locally 

as Down’s Dam, has been constructed across the river. The dam 

can retain approximately 4 feet of water behind the structure. The 

river channel is undisturbed from this point approximately to River 

Mile 23. 

Downriver from Down’s Dam, the river channel is deeply incised, 

meandering, and bordered by hardwood hammock. At several 

locations, the river flows through higher and drier land, with pinepalmetto 

flatwoods extending to the river’s edge, creating a number 

of bluffs along this river segment. The outside edges of many 

meanders display evidence of erosion, with sandbars accreting on 

the inner edges of the meanders. Much of the river bottom below


133 

Down’s Dam consists of hard limestone, and limestone outcroppings 

occur in many places along the riverbanks. In many areas, relict 

marine shells cover the river bottom and banks. 

• Deer Prairie Creek. The creek is a major tributary of the Myakka 

River that discharges into the river near the city of North Port. It 

drains 33 square miles in eastern Sarasota County, including the 

Carlton Reserve, the eastern portion of Myakka River State Park, and 

agricultural lands. A dam constructed in the creek acts as a salinity 

barrier to prohibit brackish water from moving upstream. 

• Myakkahatchee Creek/Big Slough Canal. Myakkahatchee Creek/ 

Big Slough Canal drains about 50 square miles. The creek, a 

21.5-mile main tributary of the Myakka River, begins in the southeastern 

part of Manatee County near Edgeville and flows through 

the city of North Port, where it enters the estuarine portion of the 

river. Approximately 7 miles of Myakkahatchee Creek wind through 

the incorporated parts of the city. The creek supplies the cities of 

North Port and part of Port Charlotte with potable water. The upper 

portion of Myakkahatchee Creek maintains its natural path. Years of 

flood control activities have altered the path and natural flow patterns 

of the lower reach around the city of North Port. 

The first residential development along the river is located at River 

Mile 23. From this point to Interstate 75 (I-75), at River Mile 19.5, there 

are a number of homes along the riverbank. Below I-75 there are only a few 

homes, the Snook Haven Fish Camp, and Ramblers Rest Resort. Pop ash 

swamp and marsh habitats are the dominant association along the river in 

the Lower Myakka Planning Unit. Just downstream from Snook Haven, 

the brackish water’s influence on riverbank vegetation is evidenced by the 

growth of leatherfern and other halophytic plants. Mangroves are found 

growing as far upstream as the mouth of Deer Prairie Creek. Tidal marshes 

and mangroves gradually become more extensive from this point downriver 

towards Charlotte Harbor. 

High tides can affect the Myakka River more than four miles upstream 

from U.S. Highway 41, and the Blackburn Canal may be affected by tides 

more than five miles upstream from the Venice Byway. 

Downstream of U.S. 41, both shorelines of the river have been partially 

developed. In this river segment to the Sarasota-Charlotte County 

line, the river widens and is relatively shallow, with a sandy bottom. Two 

small mangrove islands in the area contain bird rookeries. Limited development 

occurs along the western bank of the river down to the county 

line, in contrast to the eastern bank, which contains several large, fully 

developed subdivisions. Between the county line and the El Jobean Bridge 

(County Road 771), bulkheads and finger canals associated with residential 

development have replaced most of the native vegetation. Downriver from 

El Jobean, the riverbanks are relatively natural as they widen into Charlotte 

Harbor.

134 



Upper Myakka Lake experiences water quality problems, primarily 

from high nutrient levels, seasonally low DO, and a seasonal infestation of 

exotic aquatic vegetation. Large numbers of migratory waterfowl also contribute 

to nutrients in the upper and lower lake during the winter months, 

corresponding to the dry season and times of little or no flow through 

the river. 

The northern and eastern portions of the Myakka watershed lie in the 

west-central Florida phosphate mining area, where natural geologic conditions 

can cause phosphate concentrations in surface waters to be elevated 

compared with streams in other portions of the state. Annual minimum 

phosphorus and ammonium concentrations show increasing trends at a 

long-term monitoring site immediately south of Upper Myakka Lake in 

Myakka River State Park. 



sources. Table 3.10 summarizes the water quality assessment status 

of all waterbody segments in the planning unit. Waterbodies represented 

by these data include Upper Lake Myakka and mainstem river segments as 

well as the Big Slough Canal and Deer Prairie Creek. 

The table and figure show that eight waterbody segments in the planning 

unit are impaired and require a TMDL. The most common impairments 

are for nutrients and DO. 




Lower Myakka River Planning Unit. Appendix E lists the basin’s domestic 

and industrial surface discharge facilities, along with their permitted

The Lower Myakka River Planning Unit contains 18 permitted domestic 

and industrial facilities. Two of the facilities discharges less than 0.1 

mgd through surface water discharge or by land application of the effluent. 

Five of the wastewater treatment plants facilities produce reclaimed water 

for reuse. 

There are no hazardous waste sites in the planning unit. 

The planning unit contains one Class I solid waste landfill and one 

Class II solid waste landfill, both of which are closed. 

Nonpoint Sources. Urban development, agriculture, and rangeland, 

which encompass 19 percent, 15 percent, and 17 percent of the land area, 

respectively, are the major land uses in the Lower Myakka River Planning 

Unit. The remaining undeveloped land consists of wetlands (23 percent) 

and upland forests (21 percent). These land uses can be associated with 

nonpoint discharges of pollutants and eroded sediments. Appendix F 

provides summary information on general land uses in the basin, by

The downstream reaches of the Myakka River are experiencing habitat 

alterations and eutrophication. The alterations include the conversion of 

natural shorelines to hardened shorelines. In the Myakka River (usually 

regarded as pristine), the cumulative length of tidal shoreline converted to 

seawall is equivalent to all of one riverbank, from the harbor to the head 

of the tide. Other alterations include invasion by exotic plant species such 

as Brazilian pepper (Schinus terebinthifolius). These changes in shoreline 

and wetland quality reduce riverine primary production, wetland area/edge 

ratios, and the natural filtration properties of wetlands. 






Appendix B contain additional information on the requirements for 




for the list of impaired waters.

Chapter 4: The Verified List of Impaired 

Waters 

Public Participation 

The Florida Department of Environmental Protection (Department) 

has worked with a variety of stakeholders and held public meetings on 

developing and adopting the Verified Lists of impaired waters for the five 

Group 3 basins across the state. Table 4.1 lists the statewide schedule for 

the development and adoption of the Group 3 Verified Lists, including the 

public meetings. The schedule for the Sarasota Bay and Peace and Myakka 

Rivers Basin is highlighted in boldface type. 

Basin-specific draft Verified Lists of waters that met the requirements 

of the Impaired Surface Waters Rule (IWR) were made available to the 

public on June 23, 2004. The lists were placed on the Department’s Total 

Maximum Daily Load (TMDL) Web site, at http://www.dep.state.fl.us/ 

water/tmdl, and were also sent on request to interested parties by mail or 

via e-mail. 

Citizens were given the opportunity to comment on the draft lists in 

person and/or in writing. A total of 6 public meetings was held across 

the state, to encourage public participation on a basin-by-basin basis. 

The Department also accepted written comments for 45 days beginning 

June 23, 2004, and ending August 9, 2004. 

Following the public meetings for the Group 3 basins, which took 

place between June 30, 2004, and July 21, 2004, revised draft lists were 

made available to the public on September 17, 2004. The public had the 

opportunity to comment on these revised lists either in writing and/or at 

a final public meeting in Tallahassee. Comments on any of the lists were 

accepted and considered throughout the full comment period. 

The final basin-specific Verified Lists developed through the public 

participation process were adopted by Secretarial Order in November 2004, 

and were submitted to the U.S. Environmental Protection Agency (EPA) in 

December 2004 as the state’s current 303(d) list of impaired waters. 

Identification of Impaired Waters 

As discussed in Chapter 2, waters on the Verified and Planning Lists 

must meet specific thresholds and data sufficiency and data quality requirements 

in the IWR (Rule 62-303, Florida Administrative Code [F.A.C.]). 

Appendix A describes the legislative and regulatory background for the 

development of the Planning and Verified Lists. Appendix C contains a 

methodology that describes the criteria and thresholds required for both 

lists under the IWR.

Submittal to EPA as State’s 303(d) List of Impaired Waters 

Any waters that do not have sufficient data to be analyzed in accordance 

with the requirements of the IWR will remain on the 1998 303(d) 

list of impaired waters maintained by the EPA. These waters are not 

delisted, and they will be sampled during the next phases of the watershed 

management cycle so that their impairment status can be verified. 

Documentation of Reasonable Assurance 

Under the Florida Watershed Restoration Act, the Department will 

not place impaired waters on the Verified List if reasonable assurance is 

provided that these waters will attain water quality standards in the future 

and will make reasonable progress towards attaining water quality standards 

by the time the next 303(d) list of impaired waters is scheduled to be 

submitted to the EPA. Reasonable assurance can be provided if existing or 

proposed technology-based effluent limitations and other pollution control 

programs under local, state, or federal authority are expected to result in 

the attainment of water quality standards. Examples include Surface Water 

Improvement and Management Program restoration projects that provide 

ongoing monitoring, and permitted facilities that upgrade to advanced 

treatment or remove discharges to surface waters. Table 4.2 lists the major 

elements of reasonable assurance, and Appendix B provides additional 

information. 

The Southwest Florida Water Management District (SWFWMD), 

in cooperation with the Florida Department of Agriculture and Consumer 

Services (DACS) and local agricultural stakeholders in the lower Peace 

River Planning Unit, developed a watershed management plan to address 

the impairment of designated uses in the Shell and Prairie Creek watersheds 

related to total dissolved solids, chlorides, and specific conductance. 

The Department concluded that the management plan provides reasonable 

assurance that the impairments will be adequately addressed.

Based on the documentation provided, the Department specifically 

concluded that there is sufficient reasonable assurance of the following: 

1. Completed and proposed management actions in the plan will 

result in the attainment of total dissolved solids, chlorides, and 

specific conductance criteria in the following water segments: Shell 

Creek (waterbody identification number [WBID] 2041), Myrtle 

Slough (WBID 2040), and Prairie Creek (WBID 1962), and

144 


2. Reasonable progress towards continued attainment of the narrative 

nutrient criteria and associated designated uses will be made 

through 2009, which is the year that the next 303(d) list of impaired 

waters for the Peace River Basin is due to be submitted to the 

EPA. 

Key financial and technical support for implementing the plan is 

being provided by DACS, the SWFWMD, and the U.S. Department of 

Agriculture. When fully implemented, the plan will likely be one of the 

most successful water quality restoration projects in the state. 

The Verified List of Impaired Waters 

Table 4.3 contains the Verified List of impaired waters for the Sarasota 

Bay and Peace and Myakka Rivers Basin, based on the water quality 

assessment performed for the October 2004 update to the 303(d) list. 

Figure 4.1 shows waters on the Verified List for the entire basin and the 

projected year for TMDL development. 

Table D.1 in Appendix D contains the listing status of all assessed 

waters in the basin. 

Pollutants Causing Impairments 

Of the 480 water segments in the Sarasota Bay and Peace and Myakka 

Rivers Basin, 94 waters are impaired for at least 1 parameter, and a TMDL 

is required for these waters. There is a total of 99 parameter listings for 

impairment following the methodology in Appendix C. The Upper Peace 

River Planning Unit has the largest number of impaired parameter listings 

with 38, followed by the Sarasota Bay Planning Unit with 31 listings. 

The most common parameter exhibiting impairment throughout the 

Sarasota Bay and Peace and Myakka Rivers Basin is nutrients with 50 listings, 

followed by mercury in fish with 38 listings, and coliform bacteria 

with 21 listings. There are 38 segments listed due to fish consumption 

advisories for mercury; this includes the Gulf of Mexico coastal waters and 

a mainstem segment of the Peace River. The state has also issued limited 

consumption advisories for which applies to fish species having mercury 

levels of 0.5 to 1.5 parts per million. 

As required by the IWR, the Department must identify the pollutants 

causing or contributing to DO exceedances in order to place DO on the 

Verified List. If a water segment is on the Verified List for both dissolved 

oxygen (DO) and nutrients, nutrients is identified as a pollutant contributing 

to DO exceedances. The Department also applies the following analysis 

to identify the pollutant(s) contributing to DO exceedances: 

1. The water segment median values for biological oxygen demand 

(BOD), total nitrogen (TN), and total phosphorus (TP) are 

determined for the verified period (i.e., January 1, 1997, to 

June 30, 2004).

Florida’s waterbody classifications are defined as: 1—Potable water supplies, 2—Shellfish propagation or harvesting, 3F— 

Recreation, propagation, and maintenance of a healthy, well-balanced population of fish and wildlife in fresh water, 3M—Recreation, 

propagation, and maintenance of a healthy, well-balanced population of fish and wildlife in marine water, 4—Agricultural 

water supplies, 5—Navigation, utility, and industrial use.

“ln H” means the natural logarithm of total hardness expressed as mg/L of CaCO3. For metals criteria involving equations with 

hardness, the hardness shall be set as 25 mg/L if actual hardness is < 25mg/L and set at 400 mg/L if actual hardness is > 400 

mg/L. The concentration causing impairment for nutrient listings is the Median.

Priority and schedule for this WBID reflects the priority established for the WBID in the 1998 303(d) list. Where a parameter 

was 1998 303(d) listed, the priority shown for it in the 1998 303(d) list was retained if it was originally high or changed to 

medium if it was originally low. In the case of mercury, the priority remains low. Where a parameter was only identified as 

impaired under the IWR, priorities of high, medium, or low were used.

2. The median values are then compared with the screening levels 

for the appropriate waterbody type. The screening levels represent 

the 70th percentile value of data collected from streams, lakes, or 

estuaries in Florida (Table 4.4).

3. If a waterbody segment BOD median value exceeds the screening 

level, BOD is identified as a pollutant contributing to DO 

exceedances. 

4. If a waterbody segment TN or TP median values exceed the 

appropriate screening levels, and there are insufficient data to assess 

nutrients using the IWR TSI or chlorophyll a thresholds, the nutrient 

exceeding the screening level is identified as a pollutant contributing 

to the exceedances. 

Table 4.5 provides the median values for water segments where there 

is a sufficient number of DO exceedances to place the water on the Verified 

List. If a water has a sufficient number of exceedances for placement on the 

Verified List but the median values are less than the screening levels, the 

DO for that segment is included on the Planning List. 

Additionally, to place a water segment on the Verified List for nutrients, 

the Department must identify the limiting nutrient or nutrients on the 

Verified List, as required by the IWR. The following method is used to 

identify the limiting nutrient(s) in streams, lakes, and estuaries: 

1. The ratios of TN to TP are calculated for each paired value of TN 

and TP (per sampling event) collected during the verified period. 

2. The individual ratios over the entire verified period are evaluated to 

determine the limiting nutrient(s). If all the sampling event ratios 

are less than 10, nitrogen is identified as the limiting nutrient, and 

if all the ratios are greater than 30, phosphorus is identified as the 

limiting nutrient. Both nitrogen and phosphorus are identified as 

limiting nutrients if the ratios are between 10 and 30.

Adoption Process for the Verified List of Impaired Waters 

The Verified List must be submitted in a specific format (Section 62- 

303.710, F.A.C.) before being approved by order of the Department’s Secretary. 

The list must specify the pollutant and concentration causing the 

impairment. If a waterbody segment is listed based on water quality criteria 

exceedances, then the list must provide the applicable criteria. However, 

if the listing is based on narrative or biological criteria, or impairment of 

other designated uses, and the water quality criteria are met, the Verified 

List is required to specify the concentration of the pollutant relative to the 

water quality criteria and explain why the numeric criterion is not adequate. 

For waters with exceedances of the DO criteria, the Department must 

identify the pollutants causing or contributing to the exceedances and list 

both the pollutant and DO in the Verified List. 

For waters impaired by nutrients, the Department is required to identify 

whether nitrogen or phosphorus, or both, are the limiting nutrients, 

and specify the limiting nutrient(s) in the Verified List. 

The Verified List must also include the priority and schedule for 

TMDL development established for a waterbody segment and note any 

waters that are being removed from the current Planning List. In future 

watershed management cycles, the list must also note waters that are being 

removed from any previous Verified List for the basin.

Chapter 5: TMDL Development, Allocation, 

and Implementation 

Prioritization of Listed Waters 

Following the identification of impaired waters on the 303(d) list, the 

Florida Department of Environmental Protection (Department) determines 

priorities for developing total maximum daily loads (TMDLs) in Phase 3 of 

the watershed management cycle. When TMDLs are established, general 

allocations of pollutant load reductions are identified, at least to the level of 

point and nonpoint source categories. 

Because TMDLs cannot be developed for all listed waters during a 

single watershed management cycle, waterbodies will be prioritized using 

the criteria in the Impaired Surface Waters Rule (IWR) (Section 62- 

303.500, Florida Administrative Code). The rule states that when establishing 

the TMDL development schedule for waters on the Verified List, 

the Department will prioritize impaired waterbody segments according to 

the severity of the impairment and each waterbody’s designated uses, taking 

into account the most serious water quality problems, the most valuable and 

threatened resources, and the risk to human health and aquatic life. 

Under the IWR, the determination of high-, low-, and mediumpriority 

waters is based on the following criteria. 

High-priority waters: 

• Waterbody segments where the impairment poses a threat to potable 

water supplies or human health; 

• Waterbody segments where the impairment is due to a pollutant 

regulated by the Clean Water Act and the pollutant has contributed 

to the decline or extirpation of a federally listed threatened or endangered 

species, as indicated in the Federal Register listing the species; 

or 

• Waterbody segments verified as impaired that are included on the 

U.S. Environmental Protection Agency’s (EPA’s) 1998 303(d) list as 

high priority. 

Low-priority waters: 

• Waterbody segments that are listed before 2010 because of fish 

consumption advisories for mercury (due to the current insufficient 

understanding of how mercury cycles in the environment);

176 


• Canals, urban drainage ditches, and other artificial waterbody segments 

that are listed only due to exceedances of dissolved oxygen 

criteria; or 

• Waterbody segments that were not on the Planning List but were 

identified as impaired during Phase 2 of the watershed management 

cycle and were included on the Verified List, unless the segment 

meets the second high-priority criterion. 

• The EPA has also proposed assigning to this category the list of additional 

waterbody segments that the agency developed using its own 

evaluation methodology, until the Department has had the opportunity 

to investigate these waterbodies further. 

All segments not designated high or low priority are medium priority, 

and are prioritized based on the following factors: 

• The presence of Outstanding Florida Waters; 

• The presence of waterbody segments that fail to meet more than one 

designated use, i.e., aquatic life, primary contact and recreation, fish 

and shellfish consumption, drinking water, and the protection of 

human health; 

• The presence of waterbody segments that exceed an applicable water 

quality criterion or alternative threshold with a frequency of greater 

than 25 percent at a minimum confidence level of 90 percent; 

• The presence of waterbody segments that exceed more than one 

applicable water quality criterion; or 

• Administrative needs of the TMDL program, including meeting a 

TMDL development schedule agreed to with the EPA, basin priorities 

related to the Department’s watershed management approach, 

and the number of administratively continued permits in the basin. 

The Department is adhering to the TMDL schedule established in the 

Consent Decree between the EPA and Earthjustice for waters on the 1998 

303(d) list that are also identified as impaired under the IWR. 

Table 5.1 lists the high-priority waters for TMDL development in the 

Sarasota Bay and Peace and Myakka Rivers Basin. Figure 5.1 shows the 

locations of the high-priority waters in the Upper Peace River and Sarasota 

Bay Planning Units, respectively. The 22 waters listed in the table were 

also high priorities on the 1998 303(d) list. These waters are hydrologically 

connected to the other waters identified in Table 5.1 and are a part of 

the watersheds shown in Figure 5.1. Some of these associated waters have 

been identified as impaired through the assessment and are medium and 

low priorities for TMDL development. The Department will assess and 

incorporate the associated waters into the development of TMDLs for the 

high-priority waters if necessary.

Total Maximum Daily Load Development 

During Phase 3 of the watershed management cycle, TMDLs will be 

developed for both point and nonpoint sources of pollutants in impaired 

waterbodies and will be adopted by rule at the end of this phase. 

TMDL development involves determining the maximum amount of 

a given pollutant that a waterbody can assimilate and still meet the applicable 

numeric or narrative water quality criterion for the pollutant. In 

most cases, this “assimilative” capacity will be determined using computer 

modeling (both hydrodynamic and water quality models) that predicts 

the fate and transport of pollutants in the receiving waters. Modeling for 

the typical TMDL will include model setup, calibration, and verification, 

followed by a variety of model runs that determine the assimilative capacity 

of the water under worst-case conditions. 

State law and federal regulations require that TMDLs include a margin 

of safety (MOS) that takes into account “any lack of knowledge concerning 

the relationship between effluent limitations and water quality.” The EPA 

has allowed states to establish either a specific MOS (typically some percentage 

of the assimilative capacity) or an implicit MOS based on conservative 

assumptions in the modeling. To date, the Department has elected to 

establish an implicit MOS based on predictive model runs that incorporate 

a variety of conservative assumptions (they examine worst-case ambient 

flow conditions and worst-case temperature, and assume that all permitted 

point sources discharge at their maximum permitted amount). 

It is important to note that TMDLs will be developed only for the 

actual pollutants causing the impairment in the listed waterbody. These 

are called the “pollutants of concern.” In Florida, the most commonly 

listed pollutants of concern are nutrients, sediments, and coliforms. 

TMDLs will not be developed for impairments not due to pollutant discharges—for 

example, natural conditions, physical alterations such as dams 

and channelization, or changes in water flow. In other cases, a waterbody 

may be deemed potentially impaired based on bioassessment data or toxicity 

data. In these cases, the Department must determine the actual pollutant 

causing the impairment before a TMDL can be developed. 

Total Maximum Daily Load Allocation and 

Implementation 

Initial Allocation of Pollutant Loadings 

The Florida Watershed Restoration Act (FWRA) requires that a 

TMDL include the “establishment of reasonable and equitable allocations 

. . . among point and nonpoint sources. . . .” The Department refers 

to this as the “initial allocation,” which is adopted by rule. For the purposes 

of allocating the required pollutant loadings, the term “point sources” 

primarily includes traditional sources such as domestic and industrial 

wastewater discharges. 

Recent EPA guidance requires states to include as point sources those 

stormwater systems that are covered by a National Pollutant Discharge

180 


Elimination System (NPDES) stormwater permit. However, NPDESpermitted 

stormwater discharges are not subject to the same types of 

effluent limitations, cannot be centrally collected and treated, and typically 

have not invested in treatment controls to the same degree as traditional 

point sources. Nonpoint sources include intermittent, rainfall-driven, 

diffuse sources of pollutants associated with everyday human activities, 

including runoff from urban land uses, agriculture, silviculture, and 

mining; discharges from failing septic systems; and atmospheric deposition. 

These point and nonpoint definitions do not directly relate to whether 

a source is regulated. Some nonpoint sources such as stormwater systems 

are permitted under the regulatory programs of the Department or water 

management districts, while others, such as agricultural stormwater discharges, 

are not. This distinction is important because the implementation 

of the allocations to nonpoint sources outside the authority of regulatory 

programs will require cooperation from dischargers to implement best 

management practices (BMPs) voluntarily. 

While a “detailed allocation” will ultimately be necessary to implement 

a TMDL fully, a key goal of the initial allocation is to assign responsibility 

for pollutant load reductions between point and nonpoint sources. For 

point sources, allocations will be implemented through the Department’s 

NPDES wastewater and stormwater permitting programs. The implementation 

of nonpoint source load reductions will be done through a combination 

of regulatory and nonregulatory processes. 

Initial allocations of pollutant loadings will also be made to historical 

sources (e.g., the phosphorus-laden sediments at the bottom of a lake) and 

upstream sources (those entering into an impaired waterbody). Upstream 

sources include sources outside Florida, and these sources will receive 

reduced allocations similar to instate sources. 

The FWRA provided direction for the allocation of TMDLs and 

directed the Department to provide guidance on the allocation process by 

establishing an Allocation Technical Advisory Committee (ATAC), consisting 

of representatives of key stakeholder groups. The committee’s report 

recommended a three-step process for developing initial allocations and 

addressed detailed allocations for nonpoint sources, stakeholder involvement, 

the use of BMPs, and other TMDL implementation issues (Department, 

2001). A copy of the ATAC report can be found at http://www.dep. 

state.fl.us/water/tmdl/docs/Allocation.pdf. 

Implementation Programs and Approaches 

The Florida Watershed Restoration Act designates the Department as 

the lead agency in coordinating the implementation of TMDLs. Existing 

programs and approaches through which TMDLs may be carried out 

include the following: 

• Permitting and other existing regulatory programs, such as NPDES 

permits, domestic and industrial wastewater permits, and stormwater/Environmental 

Resource Permits. Table 5.2 lists the municipal 

NPDES stormwater permittees in the Sarasota Bay and Peace and 

Myakka Rivers Basin).

• Basin Management Action Plans (B-MAPs) developed under the 

FWRA; 

• Other water quality management and restoration activities, for 

example, Surface Water Improvement and Management plans 

approved under Section 373.456, Florida Statutes; 

• Pollutant trading or other equitable economically based agreements; 

• Public works, including capital facilities; or 

• Land acquisition.

182 


These programs and approaches will be carried out at local, regional, 

state, and possibly federal levels. TMDL implementation will require 

extensive stakeholder involvement throughout the state, and, in some cases, 

between Florida and other states. Appendix A provides additional details 

on the implementation programs and approaches listed here. 

Development of Basin Management 

Action Plans 

The FWRA authorizes the Department to develop B-MAPs for implementing 

TMDLs. These plans will be developed with extensive stakeholder 

input to build consensus on detailed allocations based on the initial 

general allocations to categories of discharges. 

The B-MAPs would contain final allocations, strategies for meeting the 

allocations, schedules for implementation, funding mechanisms, applicable 

local ordinances, and other elements. In cases where stakeholder consensus 

could not be reached on detailed allocations and/or a B-MAP within a 

reasonable time, the Department would develop the allocations. 

Once a B-MAP is developed, the Department will make it available for 

public review and comment. Guidance for the content and format of the 

B-MAPs is being developed; the plans are likely to include a description of 

both regulatory and nonregulatory approaches to meeting specific TMDLs.

Appendix A: Legislative and Regulatory Background on the 

Watershed Management Approach and the 

Implementation of TMDLs 

Federal and State Legislation on Surface Water Quality and TMDLs 

Clean Water Act 

Congress enacted the Clean Water Act in 1972 with the goal of restoring and 

maintaining the “chemical, physical, and biological integrity of the nation’s waters” (33 

U.S.C. § 1251[a]). The ultimate goal of the act is to eliminate the “discharge of [all] 

pollutants into navigable waters” (33 U.S.C. § 1251[a][1]). 

Section 305(b) of the Clean Water Act requires states to report biennially to the U.S. 

Environmental Protection Agency (EPA) on their water quality. The 305(b) assessment 

report provides information on the physical, chemical, biological, and cultural features of 

each river basin in Florida. This initial assessment provides a common factual basis for 

identifying information sources and major issues, and for determining the future changes, 

strategies, and actions needed to preserve, protect, and/or restore water quality. 

Understanding the physical framework of each basin allows the development of a 

science-based methodology for assessing water quality and an accurate picture of the 

waters that are most impaired or vulnerable to contamination. 

Section 303(d) of the Clean Water Act requires states to submit to the EPA lists of 

surface waters that do not meet applicable water quality standards and establish total 

maximum daily loads (TMDLs) for each of these waters on a schedule. A pollution limit 

is then allocated to each pollutant source in an individual river basin. 

A TMDL represents the maximum amount of a given pollutant that a waterbody can 

assimilate and meet all of its designated uses (see Noteworthy on Florida’s surface water 

quality classifications for a listing of these classifications). A waterbody that does not 

meet its designated use is defined as impaired. 

NOTEWORTHY: FLORIDA’S SURFACE WATER QUALITY CLASSIFICATIONS 

Florida’s water quality standards program, the foundation of the state’s program of water quality 

management, designates the “present and future most beneficial uses” of the waters of the state 

(Subsection 403.061[10], Florida Statutes [F.S.]). Water quality criteria, expressed as numeric or 

narrative limits for specific parameters, describe the water quality necessary to maintain these 

uses for surface water and ground water. Florida’s surface water is protected for five designated 

use classifications, as follows: 

Class I 

Class II 

Class III 

Class IV 

Class V 

Potable water supplies 

Shellfish propagation or harvesting 

Recreation, propagation, and maintenance of a healthy, well-balanced 

population of fish and wildlife 

Agricultural water supplies 

Navigation, utility, and industrial use (there are no state waters currently in 

this class)


Florida Watershed Restoration Act 

In 1998, the EPA settled a lawsuit with the environmental group Earthjustice over 

Florida’s TMDL Program. The Consent Decree resulting from the lawsuit requires all 

TMDLs on the state’s 1998 Section 303(d) list of impaired waters to be developed in 

thirteen years. If the state fails to develop the TMDLs, the EPA is required to do so. 

In response to concerns about the TMDL lawsuit and in recognition of the important 

role that TMDLs play in restoring state waters, the 1999 Florida legislature enacted the 

Florida Watershed Restoration Act (Chapter 99-223, Laws of Florida). The act clarified 

the Department’s statutory authority to establish TMDLs, required the Department to 

develop a methodology for identifying impaired waters, specified that the Department 

could develop TMDLs only for waters on a future state list of impaired waters developed 

using this new methodology, and directed the Department to establish an Allocation 

Technical Advisory Committee to address the allocation process for TMDLs. The act 

also declared Lake Okeechobee impaired and, as required under the TMDL Consent 

Decree, allowed the state to develop a TMDL for the lake (see Noteworthy for a 

description of the legislation’s major provisions). 

NOTEWORTHY: THE FLORIDA WATERSHED RESTORATION ACT 

The Florida Watershed Restoration Act contains the following major provisions: 

• Establishes that the 303(d) list submitted to the EPA in 1998 is for planning purposes only. 

• Requires the Department to adopt 303(d) listing criteria (that is, the methodology used to 

define impaired waters) by rule. 

• Requires the Department to verify impairment and then establish a Verified List for each 

basin. The Department must also evaluate whether proposed pollution control programs are 

sufficient to meet water quality standards, list the specific pollutant(s) and concentration(s) 

causing impairment, and adopt the basin-specific 303(d) list by Secretarial Order. 

• Requires the Department’s Secretary to adopt TMDL allocations by rule. The legislation 

requires the Department to establish “reasonable and equitable” allocations of TMDLs, but 

does not mandate how allocations will be made among individual sources. 

• Requires that TMDL allocations consider existing treatment levels and management 

practices; the differing impacts that pollutant sources may have; the availability of treatment 

technologies, best management practices (BMPs), or other pollutant reduction measures; the 

feasibility, costs, and benefits of achieving the allocation; reasonable time frames for 

implementation; the potential applicability of moderating provisions; and the extent that 

nonattainment is caused by pollutants from outside Florida, discharges that have ceased, or 

alteration to a waterbody. 

• Required a report to the legislature by February 2001 addressing the allocation process.


• Authorizes the Department to develop basin plans to implement TMDLs, coordinating with the 

water management districts, the Florida Department of Agriculture and Consumer Services 

(DACS), the Soil and Water Conservation Districts, regulated parties, and environmental 

groups in assessing waterbodies for impairment, collecting data for TMDLs, developing 

TMDLs, and conducting at least one public meeting in the watershed. Implementation is 

voluntary if not covered by regulatory programs. 

• Authorizes the Department and DACS to develop interim measures and BMPs to address 

nonpoint sources. While BMPs would be adopted by rule, they will be voluntary if not 

covered by regulatory programs. If they are adopted by rule and the Department verifies their 

effectiveness, then implementation will provide a presumption of compliance with water 

quality standards. 

• Directs the Department to document the effectiveness of the combined regulatory/voluntary 

approach and report to the legislature by January 1, 2005. The report will include 

participation rates and recommendations for statutory changes. 

Determining Impairment Based on the State’s Impaired Surface Waters Rule 

Section 303(d) of the federal Clean Water Act and the Florida Watershed Restoration 

Act describe impaired waters as those waterbodies or waterbody segments that do not 

meet applicable water quality standards. “Impairment” is a broad term that includes 

designated uses, water quality criteria, the Florida antidegradation policy, and moderating 

provisions (see Noteworthy for explanations of these terms). 

The state’s Identification of Impaired Surface Waters Rule (Rule 62-303, Florida 

Administrative Code [F.A.C.]) was developed in cooperation with a Technical Advisory 

Committee and adopted by the Florida Environmental Regulation Commission on April 

26, 2001. It provides a science-based methodology for evaluating water quality data in 

order to identify impaired waters, and it establishes specific criteria for impairment based 

on chemical parameters, the interpretation of narrative nutrient criteria, biological 

impairment, fish consumption advisories, and ecological impairment. The complete text 

of the rule is available at http://www.dep.state.fl.us/water/tmdl/docs/AmendedIWR.pdf. 

The Impaired Surface Waters Rule also establishes thresholds for data sufficiency 

and data quality, including the minimum sample size required and the number of 

exceedances of the applicable water quality standard for a given sample size that identify 

a waterbody as impaired. The number of exceedances is based on a statistical approach 

designed to provide greater confidence that the outcome of the water quality assessment 

is correct. Waters that are identified as impaired through the Impaired Surface 

Waters Rule are prioritized for TMDL development and implementation.


NOTEWORTHY: EXPLANATION OF TERMS 

• Designated uses, discussed in an earlier sidebar, comprise the five classifications applied to 

each of the state’s surface waterbodies. 

• Water quality criteria comprise numeric or narrative limits of pollutants. 

• The Florida Antidegradation Policy (Sections 62-302.300 and 62-4.242, F.A.C.) recognizes 

that pollution that causes or contributes to new violations of water quality standards or to the 

continuation of existing violations is harmful to the waters of the state. Under this policy, the 

permitting of new or previously unpermitted existing discharges is prohibited where the 

discharge is expected to reduce the quality of a receiving water below the classification 

established for it. Any lowering of water quality caused by a new or expanded discharge to 

surface waters must be in the public interest (that is, the benefits of the discharge to public 

health, safety, and welfare must outweigh any adverse impacts on fish and wildlife or 

recreation). Further, the permittee must demonstrate that other disposal alternatives (for 

example, reuse) or pollution prevention are not economically and technologically reasonable 

alternatives to the surface water discharge. 

• Moderating provisions (provided in Subsection 62-302.300[10] and Rules 62-4 and 62-6, 

F.A.C., and described in Sections 62-302.300, 62-4.244, 62-302.800, 62-4.243, F.A.C., and 

Sections 403.201 and 373.414, F.S.) include mixing zones, zones of discharge, site-specific 

alternative criteria, exemptions, and variances. These provisions are intended to moderate 

the applicability of water quality standards where it has been determined that, under certain 

special circumstances, the social, economic, and environmental costs of such applicability 

outweigh the benefits. 

Determining impairment in individual waterbodies takes place in two phases. First, 

in each river basin the Department evaluates the existing water quality data, using the 

methodology prescribed in the Impaired Surface Waters Rule, to determine whether 

waters are potentially impaired. Waters found to be potentially impaired are included on 

a Planning List for further assessment under Subsections 403.067(2) and (3), F.S. As 

required by Subsection 403.067(2), F.S., the Planning List is not used to administer or 

implement any regulatory program. It is submitted to the EPA for informational purposes 

only. 

The second step is to assess waters on the Planning List under Subsection 

403.067(3), F.S., as part of the Department’s watershed management approach (described 

in the following section). The Department carries out additional data gathering and 

strategic monitoring, focusing on these potentially impaired waters, and determines— 

using the methodology in Part III, Section 62-303.400, F.A.C.—if a waterbody is, in fact, 

impaired and if the impairment is caused by pollutant discharges. 

A Water Quality Assessment Report is produced containing the results of this 

updated evaluation and a Verified List of impaired waters. The criteria for the Verified 

List are more stringent than those for the Planning List. The Department is required to 

develop TMDLs for waters on the Verified List under Subsection 403.067(4), F.S. A 

watershed management plan (called a Basin Management Action Plan) to reduce the 

amount of pollutants that cause impairments must also be produced and implemented.


The Verified List is adopted by Secretarial Order in accordance with the Florida 

Watershed Restoration Act. Once adopted, the list is submitted to the EPA for approval 

as the state’s Section 303(d) list of impaired waters for the basin. 

Implementing TMDLs 

The Watershed Management Approach 

The Department's statewide approach to water resource management, called the 

watershed management approach, is the framework for implementing TMDLs as required 

by the federal and state governments. The approach does not focus on individual causes 

of pollution. Instead, each basin is assessed as an entire functioning system, and aquatic 

resources are evaluated from a basinwide perspective that considers the cumulative 

effects of human activities. Water resources are managed on the basis of natural 

boundaries, such as river basins, rather than political or regulatory boundaries. Federal, 

state, regional, tribal, and local governments identify watersheds not meeting clean water 

or other natural resource goals and work cooperatively to focus resources and implement 

effective strategies to restore water quality. Extensive public participation in the 

decision-making process is crucial. 

The watershed management approach is not new, nor does it compete with or replace 

existing programs. Rather than relying on single solutions to water resource issues, it is 

intended to improve the health of surface water and ground water resources by 

strengthening coordination among such activities as monitoring, stormwater 

management, wastewater treatment, wetland restoration, land acquisition, and public 

involvement. 

By promoting the management of entire natural systems and addressing the 

cumulative effects of human activities on a watershed basis, this approach is intended to 

protect and enhance the ecological structure, function, and integrity of Florida’s 

watersheds. It provides a framework for setting priorities and focusing the Department’s 

resources on protecting and restoring water quality, and aims to increase cooperation 

among state, regional, local, and federal interests. By emphasizing public involvement, 

the approach encourages stewardship by all Floridians to preserve water resources for 

future generations. 

The watershed approach is intended to speed up projects by focusing funding and 

other resources on priority water quality problems, strengthening public support, 

establishing agreements, and funding multiagency projects. It avoids duplication by 

building on existing assessments and restoration activities and promotes cooperative 

monitoring programs. It encourages accountability for achieving water quality 

improvements through improved monitoring and the establishment of TMDLs. 

The Watershed Management Cycle 

As part of the Department’s watershed management approach, TMDLs will be 

developed, and the corresponding pollutant loadings allocated, as part of a watershed


management cycle that rotates through the state’s 52 river basins over a 9-year period. 

The cycle’s five phases are as follows: 

• Phase 1: Preliminary Watershed Evaluation. For each river basin, a Basin Status 

Report is developed, containing a Planning List of potentially impaired waters that 

may require the establishment of TMDLs. The report characterizes each basin’s 

hydrologic, ecological, and socioeconomic setting as well as historical, current, and 

proposed watershed management issues and activities. It also contains a preliminary 

evaluation of major water quality parameters, water quality issues by planning unit, 

ecological resources, and basinwide pollutant loading trends related to land uses. At 

the end of Phase 1, a Strategic Monitoring Plan is developed. 

• Phase 2: Strategic Monitoring and Assessment. Additional data are collected 

through strategic monitoring and uploaded to STORET. The data are used to verify 

whether potentially impaired waters in each basin are impaired and to calibrate and 

verify models for TMDL development. At the end of Phase 2, a Water Quality 

Assessment Report is produced for each basin that contains a Verified List of 

impaired waters. The report also provides an updated and more thorough evaluation 

of water quality, associated biological resources, and current management plans. The 

Department will adopt the Verified List through a Secretarial Order and submit it to 

the EPA as the state’s Section 303(d) list of impaired waters. 

• Phase 3: Development and Adoption of TMDLs. TMDLs for priority impaired 

waters in the basin will be developed and adopted by rule. Because TMDLs cannot 

be developed for all listed waters during a single watershed management cycle due to 

fiscal and technical limitations, waterbodies will be prioritized using the criteria in the 

Identification of Impaired Surface Waters Rule (Rule 62-303, F.A.C.). 

• Phase 4: Development of a Basin Management Action Plan (BMAP). A BMAP 

will be developed for each basin to specify how pollutant loadings from point and 

nonpoint sources will be allocated and reduced in order to meet TMDL requirements. 

The plans will include regulatory and nonregulatory (i.e., voluntary) and structural 

and nonstructural strategies, and existing management plans will be used where 

feasible. The involvement and support of affected stakeholders in this phase will be 

especially critical. 

• Phase 5: Implementation of a Basin Management Action Plan. Implementation of 

the activities specified in the BMAP will begin. This includes carrying out rule 

development as needed, securing funding, informing stakeholders and the public, and 

monitoring and evaluating the implementation of the plan. 

To implement the watershed cycle, the state’s river basins have been divided into 

five groups within each of the Department’s six districts statewide, and each district will 

assess one basin each year. Table A.1 shows the basin groups for implementing the 

cycle in the Department’s districts, and Figure A.1 shows these groups and the rotating


cycle in the districts. Table A.2, which lists the basin rotation schedule for TMDL 

development and implementation, shows that it will take nine years to complete one full 

cycle of the state. 

The watershed management cycle is an iterative, or repeated, process. One of its key 

components is that the effectiveness of management activities (TMDL implementation) 

will be monitored in successive cycles. Monitoring conducted in Phase 2 of subsequent 

cycles will be targeted at evaluating whether water quality objectives are being met and 

whether individual waters are no longer impaired. The Department also will track the 

implementation of scheduled restoration activities, whether required or voluntary, to 

ensure continued progress towards meeting the TMDLs.

Figure A.1: Five-Year Rotating Basin Cycle in the Department’s Six Districts


Pollutants can enter a waterbody through point source discharges (generally from a 

specific facility) or nonpoint discharges (e.g., stormwater runoff, septic tanks). 

Government agencies, businesses, organizations, and individuals who contribute to these 

discharges will be asked to share the responsibility of attaining TMDLs through load 

allocations (the amount of a specified pollutant allotted for discharge) that are based on 

an established TMDL. Table A.3 summarizes these potentially affected stakeholders, 

and the actions they may be asked to take to help achieve a TMDL. 

Table A.3: Potentially Affected Stakeholders and Actions To Achieve TMDLs 

Potentially Affected Stakeholders 

Municipal stormwater/wastewater programs 

Commercial developers, homebuilders, individual 

homeowners 

Municipal and industrial wastewater treatment 

facilities, National Pollutant Discharge Elimination 

System (NPDES) permitted facilities 

Farming and silviculture operations 

Federal, regional, state agencies; regional and 

local water quality coalitions 

Actions To Achieve TMDL 

Reduce and treat urban stormwater runoff through 

stormwater retrofits, replacement of septic tanks 

Improve development design and construction, 

enhance best management practices, replace septic 

tanks 

Reduce pollutant loadings from permitted 

discharges 

Reduce and treat runoff through best management 

practices 

Carry out waterbody restoration projects 

Permitting and Other Approaches 

NPDES PERMITS 

All point sources that discharge to surface waterbodies require a National Pollutant 

Discharge Elimination System (NPDES) permit. These permits can be classified into two 

types: domestic or industrial wastewater discharge permits, and stormwater permits. 

NPDES-permitted point sources may be affected by the development and implementation 

of a TMDL. All NPDES permits include “reopener clauses” that allow the Department to 

incorporate new discharge limits when a TMDL is established. These new limitations 

may be incorporated into a permit when a TMDL is implemented or at the next permit 

renewal, depending on the timing of the permit renewal and workload. For NPDES 

municipal stormwater permits, the Department intends to insert the following statement 

once a BMAP is completed: 

“The permittee shall undertake those activities specified in the (Name of Waterbody) 

Basin Management Action Plan in accordance with the approved schedule set forth in the 

BMAP.”


DOMESTIC AND INDUSTRIAL WASTEWATER PERMITS 

In addition to NPDES-permitted facilities, all of which discharge to surface waters, 

Florida also regulates domestic and industrial wastewater discharges to ground water via 

land application. Since ground water and surface water are so intimately linked in much 

of the state, reductions in loadings from these facilities may be needed to meet TMDL 

limitations for pollutants in surface waters. If such reductions are identified in the 

BMAP, they would be implemented through modifications of the existing state permits. 

FLORIDA STORMWATER/ENVIRONMENTAL RESOURCE PERMITS 

With the implementation of the state’s stormwater treatment rule in 1982, Florida 

became the first state to require the treatment of stormwater from all new development. 

Today, except in the area served by the Northwest Florida Water Management District, 

new development projects receive an Environmental Resource Permit that combines 

stormwater flood protection, stormwater treatment, and wetland protection/mitigation 

into a single permit. These permits are designed to obtain 80 percent average annual load 

reduction of total suspended solids. This level of treatment may need to be increased, 

depending on the allocation of load reductions, especially for nutrients. For example, the 

St. Johns River Water Management District recently adopted basin-specific criteria for 

the Lake Apopka Basin that require the phosphorus loading from new development not to 

exceed predevelopment phosphorus loading. 

LOCAL LAND DEVELOPMENT CODES 

Since structural stormwater treatment practices can only achieve certain levels of 

load reductions, and because the hydrologic changes accompanying urban development 

often cause ecological impacts to aquatic systems, local land development codes that 

promote “low-impact development” are an important component of restoring impaired 

waters. Local codes may need to be reviewed to determine how to promote 

developments that minimize impervious surfaces (such as reduced street widths or the use 

of pervious pavements), promote the protection of vegetation, promote the protection and 

restoration of riparian buffers along streams and lakes, and adopt the principles of the 

Florida Yards and Neighborhoods Program in local landscaping codes. 

BEST MANAGEMENT PRACTICES 

Typically, BMPs refer to a practice or combination of practices that, based on sound 

science and best professional judgment, are determined to be the most effective and 

practicable means of reducing nonpoint source pollutant discharges and improving water 

quality. Both economic and technological considerations are included in the evaluation 

of what is practicable. BMPs may include structural controls (such as retention areas or 

detention ponds) or nonstructural controls (such as street sweeping or public education). 

Many BMPs have been developed for urban stormwater to reduce pollutant loadings and 

peak flows. These BMPs accommodate site-specific conditions, including soil type, 

slope, depth to groundwater, and the designation of receiving waters.


The passage of the Florida Watershed Restoration Act increased the emphasis on 

implementing BMPs to reduce nonpoint source pollutant discharges from agricultural 

operations. Recognizing that the development and adoption of BMPs might take several 

years, the legislature authorized the use of Interim Measures (IMs) during the BMP 

development process for agricultural operations. In essence, IMs are a set of logical 

conservation practices designed to reduce agricultural nonpoint pollutant discharges 

based on current knowledge and best professional judgment. These practices will evolve 

into more formal BMPs as better scientific data on their effectiveness is obtained. 

Once the Florida Department of Agriculture and Consumer Services adopts BMPs, 

the Department is charged with verifying their effectiveness in reducing agricultural 

nonpoint sources. Once verified, agricultural operations that have implemented BMPs 

will receive a waiver of liability and presumption of compliance similar to that granted a 

developer who obtains an Environmental Resource Permit. 

OTHER STRATEGIES 

The success of implementing nonpoint source TMDL load allocations will require 

variety, creativity, stakeholder commitment to watershed management, and personal 

stewardship. In addition to BMPs, other possible strategies for meeting TMDLs, 

restoring water quality, and preventing the further degradation of Florida’s watersheds 

include cost sharing, waste minimization, pollution prevention, new approaches to land 

use design and development, and pollutant trading. The Department will assemble a 

Technical Advisory Committee to help develop a pollutant-trading rule, which must be 

reviewed by the legislature prior to its adoption. The Department will also continue to 

work with local stakeholders on TMDL allocation issues and implementation plans.

Appendix B: Information on Reasonable Assurance 

TO: 

FROM: 

Interested Parties 

Mimi Drew, Director 

Division of Water Facilities 

DATE: September 2002 

SUBJECT: Guidance for Development of Documentation To Provide 

Reasonable Assurance that Proposed Pollution Control Mechanisms Will Result in 

the Restoration of Designated Uses in Impaired Waters 

The purpose of this memo is to describe the types of information that should be 

considered, and subsequently documented, when evaluating whether there is sufficient 

reasonable assurance that: 

1. Proposed pollution control mechanisms (typically described in watershed 

management or restoration plans) addressing impaired waters will result in the 

attainment of applicable water quality standards (designated uses) at a clearly 

defined point in the future, and 

2. Reasonable progress towards restoration of designated uses will be made by the 

time the next 303(d) list of impaired waters is due to be submitted to the EPA. 

There are many site-specific issues related to determining whether reasonable 

assurance has been provided. Accordingly, this document describes the elements or 

issues that should be considered when evaluating a submittal or when documenting the 

basis for the Department’s decision, rather than attempting to establish specific criteria on 

what constitutes reasonable assurance. 

It should be noted that the term “reasonable assurance” is used throughout many 

Department programs and rules, and this guidance specifically addresses the issues 

related to the “reasonable assurance” provided by proposed pollution control 

mechanisms. This guidance should not be used to evaluate the meaning of reasonable 

assurance in other contexts, particularly in permitting decisions. 

Background 

The Impaired Surface Waters Rule (IWR), Rule 62-303, F.A.C. (Identification of 

Impaired Surface Waters), establishes a formal mechanism for identifying surface waters 

in Florida that are impaired (do not meet applicable water quality standards) by 

pollutants. Most waters that are verified as being impaired by a pollutant will be listed on


the state’s 303(d) list pursuant to the Florida Watershed Restoration Act (FWRA) and 

Section 303(d) of the Clean Water Act. Once listed, Total Maximum Daily Loads 

(TMDLs) will be developed for the pollutants causing the impairment of the listed 

waters. However, as required by the FWRA, the Department will evaluate whether 

existing or proposed pollution control mechanisms will effectively address the 

impairment before placing a water on the state’s Verified List. If the Department can 

document there is reasonable assurance that the impairment will be effectively addressed 

by the control measure, then the water will not be listed on the final Verified List (other 

impaired waters that will not be listed include waters with TMDLs and waters impaired 

by pollution). 

Current Rule Text Relating to Evaluation of Pollution Control Mechanisms 

The rule text addressing the evaluation of proposed pollution control mechanisms is 

as follows: 

Section 62-303.600, Evaluation of Pollution Control Mechanisms 

1. Upon determining that a waterbody is impaired, the Department shall evaluate 

whether existing or proposed technology-based effluent limitations and other 

pollution control programs under local, state, or federal authority are sufficient to 

result in the attainment of applicable water quality standards. 

2. If, as a result of the factors set forth in (1), the waterbody segment is expected to 

attain water quality standards in the future and is expected to make reasonable 

progress towards attainment of water quality standards by the time the next 303(d) 

list is scheduled to be submitted to EPA, the segment shall not be listed on the 

Verified List. The Department shall document the basis for its decision, noting 

any proposed pollution control mechanisms and expected improvements in water 

quality that provide reasonable assurance that the waterbody segment will attain 

applicable water quality standards. 

Responsible Parties for Reasonable Assurance Demonstration 

It is ultimately the Department’s responsibility to assure adequate documentation in 

the administrative record whenever the Department decides to not list an impaired 

waterbody segment for a given pollutant. This documentation will be very important 

because the Verified Lists will be adopted by Order of the Secretary and third parties will 

be provided an opportunity to challenge, via an administrative hearing, all listing 

decisions (both those listing a water and those to not list a water for a given pollutant). 

However, the Department expects that local stakeholders will often offer to prepare the 

necessary documentation to demonstrate reasonable assurance that proposed control 

mechanisms will restore a given waterbody. The Department will provide guidance to 

stakeholders on what information is needed and how it should be submitted.


Time Frame for Development of Documentation 

The Department plans to prepare basin-specific Verified Lists as part of its 

watershed management cycle, which rotates through all of the state’s basins over a fiveyear, 

five-phased cycle 1 . During the first phase of the cycle, the Department will assess 

water quality in the basin and prepare a draft Planning List of potentially impaired 

waters. The Department and interested parties will then have approximately one year 

(Phase 2) to monitor waters on the planning list and prepare documentation, as 

appropriate, to provide reasonable assurance that impaired waters will be restored. The 

Department will review submittals from interested parties during Phase 2, before 

adopting the Verified List for the basin containing the waterbody segment in question. 

What It Means To Be Under Local, State, or Federal Authority 

Both the FWRA and the IWR require that the pollution control programs 

under consideration be “under local, state, or federal authority.” A pollution 

control program will be considered "under local, state, or federal authority" if the 

program is subject to or required by a local ordinance, state statute or rule, or 

federal statute or regulation. 

Programs will also be considered under local, state, or federal authority if they 

are subject to a written agreement, signed by both local stakeholders and at least 

one governmental entity, that includes measurable goals, performance criteria, 

benchmarks, and back-up corrective actions to assure the further progress of the 

program. It is important to note that these written agreements do not need to be 

enforceable for nonregulated nonpoint sources. 

Many nonpoint sources are currently outside of the regulatory programs of EPA, the 

Department, and the water management districts, and reductions at these nonpoint 

sources will be voluntary. In fact, pollution control mechanisms for these nonpoint 

sources would be voluntary even if a TMDL were developed. As such, these agreements 

may provide the same level of reasonable assurance that can be provided for a TMDL 

implementation plan as long as they maintain the Department’s enforcement capability 

over all point sources involved. 

Time Frame for Attaining Water Quality Standards 

The FWRA and the IWR do not establish a specific time limit by which waters must 

attain applicable water quality standards or designated uses. However, the pollution 

control mechanisms or watershed restoration plan must provide reasonable assurance that 

designated uses will be met at some time in the future. As such, the documentation 

submitted to the Department must provide a specific date by which time designated uses 

are expected to be restored. In cases where designated uses will not be met for many 

years, the documentation should also provide justification as to why the specified time is 

needed to restore designated uses. 

1 Federal regulations currently call for state 303(d) lists every two years, but Florida plans to submit annual updates 

based on the basin-specific Verified Lists.


Parameter-Specific Nature of Demonstration 

For the Department not to place an impaired waterbody segment on the Verified List, 

reasonable assurance must be provided for each pollutant that has been documented to be 

causing impairment of the waterbody segment. However, some entities, including the 

Department, may want to provide reasonable assurance addressing only selected 

pollutants, which could result in the Department not listing the waterbody segment for 

those pollutants, but still listing it for others. In this event, TMDLs will only be 

developed for the remaining listed pollutants. 

Information To Consider and Document when Assessing Reasonable 

Assurance in the IWR 

To provide reasonable assurance that existing or proposed pollution control 

mechanisms will restore designated uses, the following information should be evaluated 

and documented for the Administrative Record: 

1. A Description of the Impaired Water—name of the water listed on the Verified 

List, the location of the waterbody and watershed, the watershed/8-digit 

cataloging unit code, the NHD identifier (when they become available), the type 

(lake, stream, or estuary) of water, the water use classification, the designated use 

not being attained, the length (miles) or area (acres) of impaired area, the 

pollutant(s) of concern (those identified as causing or contributing to the 

impairment), and the suspected or documented source(s) of the pollutant(s) of 

concern. 

2. A Description of the Water Quality or Aquatic Ecological Goals—a 

description of the water quality–based targets or aquatic ecological goals (both 

interim and final) that have been established for the pollutant(s) of concern, the 

averaging period for any numeric water quality goals, a discussion of how these 

goals will result in the restoration of the waterbody’s impaired designated uses, a 

schedule indicating when interim and final targets are expected to be met, and a 

description of procedures (with thresholds) to determine whether additional 

(backup) corrective actions are needed. 

3. A Description of the Proposed Management Actions To Be Undertaken— 

names of the responsible participating entities (government, private, others), a 

summary and list of existing or proposed management activities designed to 

restore water quality, the geographic scope of any proposed management 

activities, documentation of the estimated pollutant load reduction and other 

benefits anticipated from implementation of individual management actions, 

copies of written agreements committing participants to the management actions, 

a discussion on how future growth and new sources will be addressed, confirmed 

sources of funding, an implementation schedule (including interim milestones and


the date by which designated uses will be restored), and any enforcement 

programs or local ordinances, if the management strategy is not voluntary. 

4. A Description of Procedures for Monitoring and Reporting Results—a 

description of the water quality monitoring program to be implemented (including 

station locations, parameters sampled, and sampling frequencies) to demonstrate 

reasonable progress; quality assurance/quality control elements that demonstrate 

the monitoring will comply with Rule 62-160, F.A.C.; procedures for entering all 

appropriate data into STORET; the responsible monitoring and reporting entity; 

the frequency and format for reporting results; the frequency and format for 

reporting on the implementation of all proposed management activities; and 

methods for evaluating progress towards goals. 

5. A Description of Proposed Corrective Actions—a description of proposed 

corrective actions (and any supporting document[s]) that will be undertaken if 

water quality does not improve after implementation of the management actions 

or if management actions are not completed on schedule, and a process for 

notifying the Department that these corrective actions are being implemented. 

Water Quality–Based Targets and Aquatic Ecological Goals 

Some of the most important elements listed above are the requirements to provide 

water quality–based targets or aquatic ecological goals and a discussion on how resultant 

pollutant(s) reduction targets/goals will result in restoration of designated uses. Some 

people have expressed concern about these targets because they equate a water quality– 

based restoration target with a TMDL (thus assuming a “Catch 22” that a TMDL is 

needed to make a demonstration that a TMDL is not needed). However, as is also the 

case for TMDLs, water quality–based targets can take many forms, and need not be a 

result of a complex hydrodynamic/water quality model. 

In some cases, there may be sufficient historical data (paleolimnological data, 

loadings from periods predating the impairment, or baseline data for Outstanding Florida 

Waters 2 , for example) that could be used to determine an appropriate water quality target. 

In other cases, simplified modeling (including regression analysis) may allow for 

conservative estimates of the assimilative capacity that could then be used as the basis for 

restoration goals. And, finally, a water quality target may have been developed that 

would be scientifically equivalent to (or act as the basis for) a TMDL, but the target has 

not been administratively adopted as a TMDL. In each of these cases, a sound water 

quality target could be used to evaluate whether the proposed pollution control 

mechanisms will sufficiently reduce loadings to meet the assimilative capacity of the 

water in question and result in attainment of designated uses. 

2 Baseline data would be data for the year prior to designation of the OFW.


Interim Targets 

Because it will usually take many years to restore fully the designated uses of an 

impaired water, interim water quality targets will often be needed to measure whether 

reasonable progress is being made towards the restoration of designated uses. Examples 

of such interim targets are provided in the last section of this document, but site-specific 

measures are also encouraged. 

Averaging Periods for Water Quality Targets 

While the averaging period for water quality–based targets should be consistent with 

how the underlying standard is expressed, they can often be expressed in a variety of 

ways and need not be expressed as “daily loads.” Annual averages or medians are often 

appropriate for some parameters, but shorter-term (seasonal, for example) averages may 

be necessary if the impairment is limited to specific seasons or parts of the year. Multiyear 

averages may be appropriate in limited circumstances where there is naturally high 

variation of the water quality target. 

Estimates of Pollutant Reductions from Restoration Actions 

It will often be difficult to estimate precisely the pollutant reductions that will result 

from specific restoration activities. This is particularly true for the implementation of 

best management practices (BMPs). However, to provide reasonable assurance that a 

BMP or other restoration action will reduce loadings of the pollutant of concern to a level 

that will restore the water’s designated uses, documentation should address how the 

reductions were calculated, including providing documented values from the scientific 

literature for reductions attributed to similar management actions. If the expected 

reductions are expressed as a range, the midpoint of the range should be used as the basis 

for estimating reductions, unless documentation is provided supporting the use of 

different removal efficiencies in this specific application. 

New Sources/Growth 

Another key element is the discussion on how future growth and new sources will be 

addressed. Restoration goals must address possible increased loadings of the pollutant of 

concern that are anticipated due to population growth or land use changes in contributing 

watersheds, both from point and nonpoint sources. This will be particularly important for 

waters impaired by nutrients, given that so many Florida watersheds are faced with 

continuing urban, residential, and agricultural development that results in increased 

nutrient loading from stormwater, septic tanks, and wastewater discharges. 

Examples of Reasonable Progress 

The determination of whether there will be reasonable progress towards attainment 

of water quality standards will be very site- and pollutant-specific. Documentation


should be provided supporting specific progress towards restoration of the designated 

uses of the impaired water. Possible examples of reasonable progress include, but are not 

limited to the following: 

• A written commitment to implement controls reducing loadings within a specified 

time frame from watershed stakeholders representing at least 50 percent of the 

anthropogenic load of the pollutant(s) of concern; 

• Evidence of at least a 10 percent reduction (or alternatively, a percent reduction 

consistent with meeting the water quality target by the specified date) in annual 

anthropogenic loading of the pollutant(s) of concern; 

• Evidence of at least a 10 percent decrease (or alternatively, a percent decrease 

consistent with meeting the water quality target by the specified date) in the annual 

average concentration of the pollutant(s) of concern in the water; 

• Bioassessment results showing there has been an improvement in the health of the 

biological community of the water, as measured by bioassessment procedures similar 

to those used to determine impairment and conducted in similar conditions; or 

• Adoption of a local ordinance that specifically provides water quality goals, restricts 

growth or loads tied to the pollutant(s) of concern, and provides an enforcement 

option if the proposed management measure(s) are not implemented as required. 

Reasonable progress must be made by the time the next 303(d) list is due to be 

submitted to EPA, which is currently every two years. EPA has contemplated changing 

the listing cycle to every four or five years, and the IWR was specifically worded to 

allow a longer time frame for requiring reasonable progress in the event that the listing 

cycle changes. 

Long-Term Requirements 

If at any time the Department determines that reasonable assurance and reasonable 

progress are not being met, the order adopting the Verified List will be amended to 

include the waterbody on the Verified List for the pollutant(s) in question. Additional 

reasonable progress must be made each time a waterbody is considered for listing under 

Rule 62-303, F.A.C. (every five years).

Department’s Bureau of Watershed Management in Tallahassee at 850-245-8431.


Appendix C: Methodology for Determining Impairment Based 

on the Impaired Surface Waters Rule 

The Impaired Surface Waters Rule 

To identify impaired waters in each of the state’s river basins, the Department 

evaluates water quality data using the science-based methodology in the Identification of 

Impaired Surface Waters Rule (Rule 62-303, Florida Administrative Code [F.A.C.]). The 

rule establishes specific criteria and thresholds for impairment, in addition to data 

sufficiency and data quality requirements. The methodology described in the rule is 

based on a statistical approach designed to provide greater confidence that the outcome of 

the water quality assessment is correct. The complete text of the Impaired Surface 

Waters Rule is available at http://www.dep.state.fl.us/water/tmdl/docs/AmendedIWR.pdf. 

As part of the watershed management approach, for each river basin in the state the 

Department will follow the methodology in Section 62-303.300, F.A.C., to develop a 

Planning List of potentially impaired waters to be assessed under Subsections 403.067(2) 

and (3), Florida Statutes [F.S.]. The methodology for developing the Planning List 

includes an evaluation of aquatic life use support, primary contact and recreational use 

support, fish and shellfish consumption use support, drinking water use support, and 

protection of human health. Data older than 10 years cannot be used to evaluate water 

quality criteria exceedances for the Planning List. As required by Subsection 403.067(2), 

F.S., the Planning List will not be used to administer or implement any regulatory 

program, and is submitted to the U.S. Environmental Protection Agency (EPA) for 

informational purposes only. 

After further assessment, using the methodology in Part III, Section 62-303.400, 

F.A.C., the Department will determine if waters on the Planning List are, in fact, 

impaired and if the impairment is caused by pollutant discharges. These waters are 

placed on a Verified List. The criteria for the Verified List are more stringent than those 

for the Planning List. Data older than 7.5 years should not be used to verify impairment. 

The Verified List will be adopted by Secretarial Order and forwarded to the EPA for 

approval as Florida’s Section 303(d) list of impaired waters. The Department will 

develop TMDLs for these waters under Subsection 403.067(4), F.S. 

Attainment of Designated Use(s) 

While the designated uses of a given waterbody are established using the surface 

water quality classification system described previously, it is important to note that the 

EPA uses slightly different terminology in its description of designated uses. Because the 

Department is required to provide use attainment status for both the state’s 305(b) report 

and the state’s 303(d) list of impaired waters, the Department uses EPA terminology 

when assessing waters for use attainment. The water quality evaluations and decision 

processes for listing impaired waters that are defined in Florida’s Impaired Surface 

Waters Rule are based on the following designated use attainment categories:







Table C.1 summarizes the designated uses assigned to Florida’s various surface 

water classifications.

Sources of Data 

The Department’s assessment of water quality for each basin statewide includes an 

analysis of quantitative data from a variety of sources, many of which are readily 

available to the public. These sources include the EPA’s Legacy and modernized 

STOrage and RETrieval (STORET) databases, the U.S. Geological Survey (USGS), the 

Department, the Florida Department of Health (DOH), the water management districts, 

local governments, and volunteer monitoring groups. 

Historically, the Department carried out statewide water quality assessments using 

data available in the EPA’s Legacy STORET Database; STORET makes up 

approximately 60 percent of the statewide data used in the Impaired Surface Waters Rule 

assessment. The Legacy STORET dataset is a repository of data collected and uploaded 

by numerous organizations through 1999. The Legacy STORET Database can be 

accessed at http://www.dep.state.fl.us/water/storet/index.htm. 

In 2000, the EPA created a modernized version of STORET that included new 

features designed to address data quality assurance/quality control concerns (see the new 

STORET Web site at http://www.epa.gov/storet/). However, because of software 

difficulties associated with batch uploading of data to the modernized STORET, the data 

being uploaded to the national repository decreased dramatically, and lingering problems 

have temporarily reduced STORET’s importance as a statewide data source. It houses 

only about 5 percent of the statewide Impaired Surface Waters Rule Database. 

Approximately 35 percent of the data used in the Impaired Surface Waters Rule 

assessment was provided by individual organizations that for various reasons, such as 

time constraints or resource limitations, were not able to enter their data into the national 

database. The organizations providing the largest datasets include the South Florida, 

Southwest Florida, and St. Johns River Water Management Districts; the USGS; and the 

University of Florida LakeWatch volunteer monitoring group. Several of these databases


are readily available to the public via the Internet: the South Florida Water Management 

District at http://www.envirobase.usgs.gov/, the USGS at http://water.usgs.gov/, and 

LakeWatch at http://lakewatch.ifas.ufl.edu/. 

The Department created the Impaired Surface Waters Rule Database in 2002 to 

evaluate data simultaneously in accordance with the Impaired Surface Waters Rule 

methodology for every basin in the state, based on the appropriate data “window.” For 

the Verified List assessment, the window is 7.5 years (for the Impaired Surface Waters 

Rule Database), and the Planning List assessment window is 10 years. Table C.2 shows 

the periods of record for the Verified and Planning Lists for the five basin groups. 

The evaluation of water quality in the state’s basins also includes some qualitative 

information. These sources are described in the Basin Status Reports and Water Quality 

Assessment Reports for each basin.

Period of Data Record Used in Impaired 

Surface Waters Rule Evaluation 

Group 1 Planning List January 1, 1989 – December 31, 1998 

Verified List January 1, 1995 – June 30, 2002 









Note: Typically, a 10-year data record is used for the development of the Planning Lists, and a 7.5-year record is used for 

the Verified Lists. 

Methodology 

To determine the status of surface water quality in individual river basins in Florida, 

three categories of data—chemistry data, biological data, and fish consumption 

advisories—were evaluated to determine potential impairments for the four designated 

use attainment categories discussed earlier: aquatic life, primary contact and recreation, 

fish and shellfish consumption, drinking water use, and protection of human health. 

Aquatic Life Based Attainment 

The Impaired Surface Waters Rule follows the principle of independent applicability. 

A waterbody is listed for potential impairment of aquatic life use support based on 

exceedances of any one of four types of water quality indicators (numeric water quality 

criteria, nutrient thresholds, biological thresholds, and toxicity data).


EXCEEDANCES OF NUMERIC WATER QUALITY CRITERIA 

The chemistry data from STORET used in evaluating impairment were also used for 

preparing the state’s 305(b) report. Only ambient surface water quality stations were 

included in the assessment of impairment. Water quality information from point sources 

or wells was excluded. Monitoring stations were classified as one of five waterbody 

types—spring, stream, lake, estuary, or blackwater—based on criteria described in the 

latest 305(b) report. The assessments included the following parameters: 

Metals 

Nutrients 

Conventionals 

Arsenic, aluminum, cadmium, chromium VI, chromium III, 

copper, iron, lead, mercury, nickel, selenium, silver, 

thallium, and zinc 

Chlorophyll a for streams and estuaries, and Trophic State 

Index (TSI) (chlorophyll a, total nitrogen, and total 

phosphorus) for lakes 

Dissolved oxygen (DO), fecal coliforms, total coliforms, 

pH, unionized ammonia 

The requirements for placing waters on the Planning List included a minimum of 10 

temporally independent samples from the 10-year period of record shown in Table C.2, 

unless there were 3 exceedances of water quality or 1 exceedance of an acute toxicity 

criterion in a three-year period. The screening methodology for the Verified List requires 

at least 20 samples from the last 5 years preceding the Planning List assessment. An 

exceedance, meaning that water quality criteria or standards are not met, is recorded any 

time the criterion is exceeded by any amount. An exceedance for DO, however, means 

that a waterbody does not meet the DO criterion, rather than an actual exceedance of the 

criterion. 

To determine if a water should be placed on the Planning List for each parameter, the 

chemical data were analyzed using a computer program written to assess the data, based 

on criteria established in the Impaired Surface Waters Rule, with two exceptions. First, 

unionized ammonia data were not analyzed by the program, but rather with an Excel 

spreadsheet. Second, because the full complexity of the pH criterion could not be 

programmed, the incomplete listings for pH are not included. They will be further 

examined while additional data are collected during Phase 2 of the watershed 

management cycle. Data analysis and statistical summaries of WBIDs, waterbody types, 

and parameters obtained from the STORET Database were conducted using Access, SAS 

statistical software, and ArcView GIS applications 

The data for metals and conventional parameters were compared with the state 

surface water quality criteria in Section 62-302.530, F.A.C. (Identification of Impaired 

Surface Waters Rule). The rule contains a table of sample numbers versus exceedances. 

A waterbody was placed on the Planning List if there was at least 80 percent confidence 

that the actual criteria exceedance rate was greater than or equal to 10 percent. To be 

placed on the Verified List, at least a 90 percent confidence rate was required.


EXCEEDANCES OF NUTRIENT THRESHOLDS 

The state currently has a narrative nutrient criterion instead of a numeric value for 

nutrient thresholds. The narrative criterion states, “In no case shall nutrient 

concentrations of a body of water be altered so as to cause an imbalance in natural 

populations of aquatic flora or fauna.” The Impaired Surface Waters Rule provides an 

interpretation of the narrative nutrient criterion. In general, the Trophic State Index (TSI) 

and the annual mean chlorophyll a values are the primary means for assessing whether a 

waterbody should be assessed further for nutrient impairment. 

The rule also considers other information that might indicate an imbalance in flora or 

fauna due to nutrient enrichment, such as algal blooms, excessive macrophyte growth, a 

decrease in the distribution (either in density or aerial coverage) of seagrasses or other 

submerged aquatic vegetation, changes in algal species richness, and excessive diel 

oxygen swings. 

Potential nutrient impairment was evaluated by calculating annual mean chlorophyll 

a values for estuaries and streams and the TSI for lakes. For lakes, the TSI was 

calculated using chlorophyll a, total phosphorus, and total nitrogen measurements. Direct 

evidence of imbalances of flora and fauna in waterbodies was also considered in the 

evaluation of nutrient impairments. 

In estuarine areas, a water was considered nutrient enriched if the annual mean 

chlorophyll a values were greater than 11 micrograms per liter (μg/L) or if annual mean 

chlorophyll a values increased by more than 50 percent over historical values for at least 

two consecutive years. For streams, a water was considered nutrient enriched if the 

annual mean chlorophyll a values were greater than 20 μg/L or if the annual mean 

increased by more than 50 percent over historical values for at least two consecutive 

years. 

A lake with a mean color greater than 40 platinum cobalt units (PCUs) was 

considered nutrient enriched if the annual mean TSI exceeded 60. A lake with a mean 

color less than or equal to 40 PCUs was considered nutrient enriched if the annual mean 

TSI exceeded 40. In addition, a lake was considered nutrient enriched if there was an 

increase in TSI over the 1989 to 2000 period or if TSI measurements were 10 units higher 

than historical values. 

EXCEEDANCES OF BIOLOGICAL THRESHOLDS 

Bioassessments were carried out for streams, lakes, canals, and rivers using the 

Impaired Surface Waters Rule as guidance and following the Department’s standard 

operating procedures, which provide definitions and specific methods for the generation 

and analysis of bioassessment data. These are referenced in the individual bioassessment 

data tables contained in the Basin Status Reports. The purpose behind using a 

bioassessment methodology in surface water characterizations is that biological 

components of the environment manifest long-term water quality conditions and thus 

provide a better indication of a waterbody’s true health than discrete chemical or physical 

measurements alone. Similar to water quality criteria, bioassessment methods involve 

the identification of a biological reference condition, based on data from unimpaired or 

least impacted waters in a given region.


For the Planning and Verified List assessments, the reference condition data were 

used to establish expected scores, ranging from best to worst, for various measures of 

community structure and function, such as numbers or percentages of particular species 

or feeding groups. Data on community structure and function from waters of unknown 

quality in the same region as reference waters were compared with the expected scores of 

metrics to evaluate their biological integrity. 

Metrics (e.g., number of taxa, percent Diptera, percent filter feeders) were used 

independently and as an aggregated group called an index. Indices have advantages over 

individual metrics in that they can integrate several related metrics into one score that 

reflects a wider range of biological variables. A number of bioassessment metrics and 

indices exist for assessing populations of plant and animal life, including fish, diatoms 

(e.g., microscopic algae and unicellular plankton), and macroinvertebrates (e.g., insects, 

crayfish, snails, and mussels). 

Only macroinvertebrate data from ambient sites in state surface waters were used in 

the bioassessments analyzed for the Planning and Verified Lists. The data included sites 

designated as test and background sites for NPDES fifth-year inspections, but excluded 

data from effluent outfalls from discharging facilities or data from monitoring sites not 

clearly established to collect ambient water quality data. Because site-specific habitat 

and physicochemical assessment information (e.g., percent suitable macroinvertebrate 

habitat, water velocities, extent of sand or silt smothering, and riparian [Definition: Of, 

on, or relating to the banks of a natural course of water.] buffer zone widths) was not 

available at the time of reporting, it was not included. However, this information is 

instrumental in pinpointing the causes for failed bioassessment metrics and will be 

included in future reporting. 

The data used to develop the Planning and Verified Lists were obtained from the 

Department’s Biological Database (SBIO) and the EPA’s STORET Water Quality 

Database, where it could be substantiated that the data were generated in compliance with 

the bioassessment standard operating procedures referenced in the Impaired Surface 

Waters Rule (Section 62-303.330, F.A.C.). 

The data from these databases are used without regard to the randomness of sample 

site selection. For the purposes of the Basin Status Reports, the seasons are defined as 

follows: winter (1/1–3/31), spring (4/1–6/30), summer (7/1–9/30), and fall (10/1–12/31). 

Wet seasons are generally spring and summer, and dry seasons are fall and winter, 

although conditions can vary in the state as a whole. 

LAKE CONDITION INDEX 

The scoring of the individual metrics of the Lake Condition Index (LCI), except 

percent Diptera, was performed according to the following formula: 

100(B/A) where A = the 95 percentile of the reference population and B = observed 

value 

For percent Diptera, the following formula was used:


100 (100-B)/(100-A) where A = the 95 percentile of the reference population and B 

= observed value 

An average LCI score was calculated by averaging the scores of the six metrics in 

the method: total number of taxa; total number of taxa belonging to the orders 

Ephemeroptera, Odonata, and Trichoptera (EOT taxa); percent EOT taxa; Shannon- 

Wiener Diversity Index score; Hulbert Index score; and percent Dipteran individuals. 

LCI calculations were only provided for clear lakes (< 20 platinum cobalt units [PCUs]). 

As macroinvertebrate-based indices have not been shown to assess colored lakes in 

Florida accurately (> 20 PCUs), they have been excluded from bioassessments. A poor 

or very poor rating based on the average score constituted a failed bioassessment, based 

on the Impaired Surface Waters Rule. 

STREAM CONDITION INDEX 

A total Stream Condition Index (SCI) score was calculated by adding the scores of 

the seven metrics in the method: total number of taxa; total number of taxa belonging to 

the orders Ephemeroptera, Plecoptera, and Trichoptera (EPT taxa); percent Chironomid 

taxa; percent dominant taxa; percent Diptera; percent filter feeders; and Florida Index. A 

poor or very poor rating based on the total score constituted a failed bioassessment, based 

on the Impaired Surface Waters Rule. The Basin Status Reports contain definitions and 

specific methods for the generation and analysis of bioassessment data. 

BIORECON 

To establish an impairment rating based on BioRecon data, three metrics were used: 

the Florida Index score, total number of taxa, and total number of EPT taxa. If all three 

metrics failed to meet thresholds, the water was deemed “impaired” based on the 

Impaired Surface Waters Rule. 

BIOLOGICAL INTEGRITY STANDARD 

Quantitative data, generated through the use of Hester-Dendy artificial substrate 

samplers, were used to calculate Shannon-Wiener Diversity Index scores for paired 

background and test sites, as specified in the Biological Integrity Standard of Subsection 

62-302.530(11), F.A.C. One failure of the standard meant that a waterbody segment was 

listed as potentially impaired. 

EVALUATION OF TOXICITY DATA 

Although the Impaired Surface Waters Rule describes the use of toxicity data for the 

assessment of aquatic life-based attainment, no ambient toxicity data are available for 

assessment and this metric was not used. 


For Class I, II, or III waters, a waterbody was potentially impaired if the following 

criteria were met:


• The waterbody segment did not meet the applicable water quality criteria for 

bacteriological quality, 

• The waterbody segment included a bathing area that was closed by a local health 

department or county government for more than 1 week or more than once during a 

calendar year based on bacteriological data, 

• The waterbody segment included a bathing area for which a local health department 

or county government issued closures, advisories, or warnings totaling 21 days or 

more during a calendar year based on bacteriological data, or 

• The waterbody segment included a bathing area that was closed or had advisories or 

warnings for more than 12 weeks during a calendar year based on previous 

bacteriological data or on derived relationships between bacteria levels and rainfall or 

flow. 


For Class I, II, or III waters, a waterbody was potentially impaired if it did not meet 

the applicable Class II water quality criteria for bacteriological quality, or if a fish 

consumption advisory had been issued. Fish consumption advisories were based on the 

Florida Department of Health’s “limited consumption” or “no consumption” advisories 

for surface waters because of high levels of mercury in fish tissue. In addition, for Class 

II waters, waterbody segments that had been approved for shellfish harvesting but were 

downgraded to a more restrictive classification were listed as potentially impaired. 

Drinking Water Attainment and Protection of Human Health 

For Class I waters, a waterbody was potentially impaired if it did not meet the 

applicable Class I water quality criteria.


Appendix D: Integrated Assessment (Master List) for the 

Sarasota Bay and Peace and Myakka Rivers Basin 

Data collected since the 2002 update of the 303(d) list were used to update the listing 

status of waters. Table D.1 contains the listing status of all assessed waters in the basin. 

It should be noted that subsequent to the 2002 update of the 303(d) list, some waterbody 

segments were further subdivided to produce separate segments for lakes versus their 

surrounding watersheds. Therefore, Table D.1 shows the WBIDs under which these 

segments were designated in the 1998 303(d) list, as well as the new or currently 

recognized WBIDs for them. 

Information in this appendix was obtained from an inventory of the Legacy and 

modernized STORET databases, as well as data contributed directly to the Department by 

individual data providers. Table D.2 includes only stations with data from the Planning 

and Verified assessment periods.

2 The EPA’s 305(b)/303(d) Integrated Report categories are as follows: 

1 – Attains all designated uses; 

2 – Attains some designated uses; 

3a – No data and information are available to determine if any designated use is attained; 

3b – Some data and information are available, but they are insufficient for determining if any designated use is attained; 

3c – Meets Planning List criteria and is potentially impaired for one or more designated uses; 

4a – Is impaired for one or more designated uses and the TMDL is complete;


4b – Is impaired for one or more designated uses, but no TMDL is required because an existing or proposed pollutant control mechanism provides 

reasonable assurance that the water will attain standards in the future; 

4c – Is impaired for one or more designated uses but no TMDL is required because the impairment is not caused by a pollutant; and 

5 – Water quality standards are not attained and a TMDL is required.

This waterbody was placed in 

Category 4c because it does not meet 

the applicable DO criterion, but the 

low DO levels are not due to a 

pollutant. The Department evaluated 

the available nutrient, BOD, and land 

use information for the WBID, and this 

review did not reveal any reason to 

believe the low DO values are linked 

to a pollutant. Therefore, the 

Department believes the low DO 

levels are due either to pollution (e.g. 

hydrologic modifications) or are 

representative of natural conditions, 

or both.

NOTE: Brownfields are abandoned, idled, or underused industrial and commercial facilities where 

expansion or redevelopment is complicated by real or perceived environmental contamination. The primary 

goals of Florida's Brownfields Redevelopment Act are to reduce health and environmental hazards on 

existing commercial and industrial sites that are abandoned or underused due to these hazards and create 

financial and regulatory incentives to encourage the voluntary cleanup and redevelopment of sites.
