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.
Gorman Lake has elevated nutrient levels and drains into the Cannon River. This project will provide a subgrant to the Gorman Lake Association to install a two-tiered retention pond to reduce both phosphorus and peak flow from a drainage ditch from reaching Gorman Lake. Project partners include three agricultural producers, the Le Sueur Soil and Water Conservation District and the Natural Resources Conservation Service.
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.
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.
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.
