This project will improve surface and groundwater quality in the rural sections of the Vermillion and North Cannon River Watersheds located in Dakota County through the installation of targeted structural and vegetative conservation practices. This project will leverage local and federal funds to provide technical and financial assistance to landowners that install agricultural water quality practices.
A direct appropriation of $400,000 in FY 2010 for the Anoka Conservation District (ACD) is for the metropolitan landscape restoration program for water quality and improvement projects in the seven-county metro area (the law also provides $600,000 for this purpose in FY2011).

The Cannon River Watershed is a diverse watershed from the standpoint of topography, land use, and land cover, but a central issue of concern is increased sedimentation and turbidity within the river. One of the best ways to keep sediment from entering the Cannon River is to install vegetative buffers on the smaller tributaries in the upper reaches of the watershed. This project is important as it aims to help identify strategic locations where buffers are needed and to assist landowners to install buffers that will directly help reduce sedimentation within the watershed.
Through a long standing partnership, this project will continue to implement a process formalized with a 2010 Clean Water Fund Grant to conduct stormwater sub-watershed assessments. The goal of the sub-watershed assessments is to accelerate water quality improvements by focusing efforts in high priority areas. Specifically, subwatershed assessments are a tool used to identify the most effective urban stormwater conservation practice by location.
The Straight River runs through Owatonna and is considered a priority water resource for the city. Untreated stormwater from city roofs, streets and parking lots are jeopardizing the water quality of river. Through this project, the city will install four rain gardens in city parks that will capture and rapidly absorb stormwater runoff from streets and driveways. The implentation of these rain gardens throughout the city will reduce the volume of stormwater entering the Straight River.
Water from an area in and near the interchange of US Highway 52 and MN Highway 55 spills onto a steep bluff face at the head of a ravine. This has accelerated the amount of sediment eroding from the ravine into the Mississippi River. In partnership with Dakota County, Dakota Soil and Water Conservation District, the City of Rosemount, Minnesota Department of Transportation, Flint Hills Resources, the Vermillion River Watershed Joint Powers Organization has been working for several years to identify a solution to this severe erosion problem.
The 400-mile stretch of the Mississippi River from its headwaters at Lake Itasca to Morrison County near Little Falls is the focus of this project. Working in cooperation with the eight member counties, this project will develop implementation plans and strategies geared specifically for the Mississippi River and incorporate them into the individual County Comprehensive Local Water Plans. These recommendations will be for specific strategies, often crossing county boundaries for implementation.
Schwanz Lake is an 11.5-acre shallow lake in southeast Eagan that was found to be impaired in 2006 due to excessive levels of phosphorus. The land area draining to the lake is 762 acres, but a small a 28-acre residential neighborhood was found to disproportionately contribute 24 percent (roughly 14 lbs/yr) of the phosphorus, according to a 2010 study of phosphorus sources. The neighborhood was developed before Eagan established water quality requirements for stormwater retention ponds and the neighborhood drains runoff directly to the lake through a single pipe.
The Greater Blue Earth River Basin is a large area within the Watonwan, Le Sueur, and Blue Earth River watersheds. Recent research by University of Minnesota, the National Center for Earth Dynamics, and others has found this basin to be the largest contributor of sediment to Lake Pepin.
Through the Stormwater Retrofit Partnership, the Dakota Soil and Water Conservation District (DSWCD) provides the funding and technical assistance to prioritize and install Best Management Practices (BMPs) at existing public facilities. This project is needed because, like other urban properties that developed before stormwater regulations, most government owned facilities were designed and constructed without optimal water quality features.
This project will continues the successful 2010 Stormwater Retrofit Partnership. This resulted in the retrofit of 18 sites including eleven bioretention cells and seven snowmelt management areas. These retrofits provided treatment for 28 acres of urban drainage area - reducing total suspended solids, total phosphorus and stormwater volumes.
The Greater Blue Earth River Basin Alliance (GBERBA), a nine County/SWCD JPO has identified buffers as a basin priority. This initiative will work towards the goal of identifying all DNR protected shoreland in the GBERBA counties without a 50 foot vegetative buffer. Buffer strips protect surface and groundwater from a multitude of pollutants. During stormwater run off events buffers can remove between 50 and 100 percent of nutrients, pesticides, pathogens, and sediment. The estimated sediment reduction for this project is 756 tons per year prevented from entering our waters.
