Lake Minnewaska Phase I Resource Investigation – 2013<br />
Sponsor: Pope Soil & Water Conservation District<br />
Funding: CWP (Grant) $112,435<br />
Purpose: This project will hire a half time employee for<br />
three years responsible for meeting the requirements<br />
outlined in the preparation of a diagnostic study<br />
and implementation plan guidance document.<br />
The requirements are as follows but not limited to:<br />
monitoring water quality, compiling data, gathering<br />
public comments, identifying priority areas, providing<br />
timelines and cost estimates for BMPs and writing a<br />
detailed report The resource investigation report will<br />
explore land use in the watershed, point and nonpoint<br />
pollution sources, agricultural practices being used,<br />
lakeshore development, septic system compliance, and<br />
water quality trends.<br />
Cottonwood Streambank Inventory and Prioritization<br />
Project – 2012<br />
Sponsor: Redwood-Cottonwood Rivers Control Area (RCRCA)<br />
Funding: Section 319 (Grant) $297,000<br />
Purpose: This RCRCA project will promote agricultural<br />
BMPs projects, identify sensitive areas for projects,<br />
inventory and prioritize project need, provide costshare<br />
funding for BMP implementation, particularly<br />
the remediation of stream bank failures through<br />
direct streambank restoration and practices that slow<br />
hydrologic processes; identify high erosion streambanks<br />
and near-channel grade stabilization/ravine problems<br />
along the Cottonwood River corridor and create a<br />
method to prioritize the sites; and provide necessary<br />
project administration, meeting all grant requirements.<br />
Le Sueur River<br />
Le Sueur <strong>Watershed</strong> Targeted Conservation Practices –<br />
2012<br />
Sponsor: Minnesota State University – Mankato – Water<br />
Resources Center<br />
Funding: Section 319 (Grant) $82,491<br />
Purpose: The Water Resources Center at Mankato will<br />
form a steering committee to serve an advisory role for<br />
the project; collect and organize data on existing BMP<br />
implementation, targeting and modeling research and<br />
other data for the map production; complete tillage<br />
transect survey/WinTransect; determine what existing<br />
laws or regulations, location and type of BMPs to target;<br />
complete “Flow Calculation Modeling”; actively seek<br />
out willing stakeholders through the “Le Sueur Civic<br />
Engagement Project”; provide project information to<br />
local government units meetings; provide a project<br />
survey, and data usage analysis; and manage and<br />
coordinate project administration.<br />
Lower Minnesota River<br />
Assessing Iron Enhanced Filtration Trenches – 2011<br />
Sponsor: City of Prior Lake<br />
Funding: Section 319 (Grant) $240,000<br />
Purpose: The purpose of this project is to quantify the<br />
performance of full-scale, field-installed, iron-enhanced<br />
filtration trenches which will provide critical design,<br />
construction, and performance information for a practice<br />
that could be used to significantly reduce the dissolved<br />
phosphorus load entering wetlands, rivers, and lakes in<br />
Minnesota.<br />
This project will investigate the design of a new<br />
treatment system that utilizes a sand filter enhanced<br />
with iron shavings or steel wool around the perimeter<br />
and near the outlet of a wet detention basin. When<br />
stormwater enters the basin, the water level will increase<br />
and stormwater will begin flowing into the filtration<br />
trenches. Significant particulate removal occurs through<br />
settling within the wet detention basin and additional<br />
particle and dissolved pollutant capture occurs by<br />
filtration and adsorption within the enhanced media<br />
trench. The technology was tested during the summer of<br />
2010 through funding provided by the City of Prior Lake,<br />
the Prior Lake Spring Lake <strong>Watershed</strong> District, and the<br />
Scott County <strong>Watershed</strong> Management Organization.<br />
Blackhawk Lake Protection Project – 2013<br />
Sponsor: City of Eagan<br />
Funding: CWP (Grant) $46,500<br />
Purpose: The City of Eagan will collaboratively develop<br />
educational programs and materials for the Black<br />
Hawk Middle School and Deerwood Elementary School<br />
community and will determine the most appropriate<br />
opportunities for community education and involvement<br />
in site analyses and selection, design, installation,<br />
operation, and maintenance of selected BMPs.<br />
