South Central Technical Service Area (SCTSA) will use this Clean Water Fund grant to provide Soil and Water Conservation Districts and other local organizations in its eleven-county area with a Geographic Information System (GIS) Technician to assist in using available GIS information to target specific locations where Best Management Practices (BMPs) can be installed to help improve water quality.
With limited funds and limited staff time available for targeting critical service areas and implementing Best Management Practices (BMPs), Geographic Information System (GIS)-based tools that pinpoint locations where BMPs will have the highest effectiveness are increasingly important. The Blue Earth County/SWCD Watershed Implementation Targeting project will utilize LiDAR topographic data to determine areas of high importance for BMP implementation. The county is located in the Blue Earth, LeSueur, Watonwan and Middle Minnesota watersheds where there is a high density of impaired waters.
This project will conduct Inventory and Inspection of four drainage ditches in Blue Earth County: JD116, CD5, CD86 and CD56. The inventory of these drainage ditches is important in order to identify where erosion, sediment and/or nutrients contribute substantially to water quality degradation. The project will also prioritize sites for future side inlet control, buffer strip implementation, and/or storage and treatment implementation.
Currently, over 235 miles of open ditch are under the jurisdiction of the Brown County Ditch Authority. A majority of Brown County public ditches drain into large, impaired rivers including the Minnesota River (Turbidity), Cottonwood River (Turbidity/Fecal Coliform), Little Cottonwood River (Turbidity/Fecal Coliform) and Watonwan River (Turbidity/Fecal Coliform). Thus far the Brown County Drainage Authority has been inventorying ditches as requested for repair by residents in the ditch system.
Ramsey-Washington Metro Watershed District (RWMWD) will improve water quality in Casey Lake and ultimately Kohlman Lake through the installation of approximately 25 rain gardens on priority properties identified as part of the Casey Lake Urban Stormwater Retrofit Assessment completed by Ramsey Conservation District (RCD) in 2011.
The purpose of this project is to reduce phosphorus loading to Crystal Lake transported primarily through County Ditch 56. Crystal Lake is listed on MPCA's 303d listing for phosphorus impairment. Increased phosphorus levels have caused toxic algal blooms, reducing its appeal to recreationalists and economic draw for the City of Lake Crystal. This project will directly address phosphorus sources from agricultural land.
This project will layer hydrologic, hydraulic, geomorphic, and pollutant loading analysis with existing countywide PTMApp outputs to identify the four highest priority areas for BMP implementation in an eastern Nicollet County ravine system experiencing dramatic mass wasting events. Three alternatives for each priority site will be presented, including an evaluation of water quality benefit, construction costs, and a cost-benefit summary.
This project is a cooperative effort between Crow Wing and Itasca County to contract with RMB Laboratories to generate 65 lake assessment/trend analysis reports. The watershed protection model is an innovative and proactive approach to water resource management which is geared towards prioritizing areas of concern, targeting implementation strategies, and measuring their effectiveness. These assessments are also useful and understandable tools for lake associations and the public.
The Greater Blue Earth River Basin Alliance (GBERBA) along with Soil and Water Conservation Districts, Counties, landowners, and drainage authorities in the ten member counties will install conservation drainage practices to improve water quality. 103E drainage systems with documented sediment or water quality issues are the focus with the goal of installing 52 practices such as improved side inlets (grade stabilization structures), alternative tile inlets, denitrifying bioreactors, saturated buffers, storage wetlands and others.
Nicollet County is located in south central Minnesota and is bordered on two sides by the Minnesota River. A line of forested bluffs separate the river valley from land that is relatively flat and historically used for agricultural purposes. Approximately 245,000 acres of the County are actively farmed. The 2012 impaired waters list for water bodies located in Nicollet County include the Minnesota River, Seven Mile Creek, Rogers Creek and tributaries to the Rush River.
As part of the FY 2012 funding cycle, the Board of Water and Soil Resources granted funds for development of the Water Quality Decision Support Application (WQDSA). The WQDSA will provide land and water managers with geospatial data and online tools to prioritize, market, and implement actions on the landscape to achieve water quality objectives identified in local and state water plans and to ensure that public funding decisions are strategic and defensible.
The Red Lake Watershed District will create an inspection database for 103E ditches under their drainage authority. The district will acquire a database software solution to conduct field inspections and to track ditch maintenance projects and use the software to facilitate compliance with state statutes. The project will also develop a process for completing the annual inspection and reporting requirements under Statue 103E.
The Cannon River is a designated Wild and Scenic River that originates in Rice County and joins the Mississippi River 120 miles downstream near Red Wing. The Upper Cannon, which encompasses 29% of the entire watershed, has been identified as a priority subwatershed.
