Rocky Brushy Creek Watershed Mgmt. Plan (2007) -- Part 2

CHAPTER 9Groundwater levels in the Northwest Hillsborough area as represented by three monitoring wells,(EWWF 11 FLDN, EWWF 2S DEEP, AND COSME 3-FLDN) indicate that groundwater elevationsfor March 2006 are declining from those observed in April 2006, but they have not reached thehistorical low for March (Table 9-3).Table 9-3Comparison of Groundwater Elevations (NGVD)in Northwest Hillsborough Area(Source: SWFWMD, Hydrologic Conditions Report – March 2006)WELLWATER LEVEL,MARCH, 2006CHANGE FROMPRIOR MONTHMARCHHISTORICALLOW LEVELLOW LEVELFOR PERIODOF RECORDCOSME 3 FLDN 21.47 -5.45 20.77 10.94EWWF 11 FLDN 14.32 -2.57 7.33 0.31EWWF 2S DEEP 16.45 -2.29 6.62 -1.16The Northern Tampa Bay Phase II (NTB II) project was initiated by SWFWMD as an outgrowth ofthe 1989 declaration of the NTBWUCA and the Northern Tampa Bay Water Resource AssessmentProject (WRAP) which was completed in 1996. This study will continue through 2010 and willinclude assessments of the biological and hydrological conditions in Northern Tampa Bay tosupport the development of minimum flows and levels, water resource recovery, water usepermitting, and environmental resource permitting. NTB II consists of a series of technical projectsin Northern Tampa Bay to support the ongoing development of minimum flows and levels, waterresources recovery, water use permitting, and environmental resource permitting.The goal of the NTB II project is to enhance the data collection effort, implement projects for theassessment of water supply needs, and to develop a water resources recovery strategy. As of2005, 30 nested groundwater monitoring sites have been installed and 50 new wetland monitoringsites have been established, many of them in the Northwest Hillsborough area. These projectsinclude detailed assessments of water resources and involve intensive data collection andmonitoring to characterize hydrologic conditions and determine the effects of water withdrawals(SWFWMD, 2000).9-11 Rocky/Brushy Creek Watershed Management Plan
