A collaboration between the Roseau County SWCD and the Roseau River Watershed District (RRWD), the CD 8 Subwatershed Sediment Reduction Project will reduce sediment delivery to the Roseau River by implementing Best Management Practices on sites that have been identified as the greatest contributors of sediment. Sites were prioritized based on modeled data from the Watershed District's Site Prioritization Grant, and the International Watershed Institutes's Water Quality Decision Support Application (WQDSA) and local knowledge of the subwatershed.
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.
The goal of this project is to develop a Roseau Lake Water Quality Improvement Report that will include a prioritized, targeted, and measurable implementation plan that will improve water quality in the Roseau Lake watershed. The project will result in development of site specific implementation actions through use of the Prioritize, Targeting, and Measuring Application (PTMApp) and the Drained Wetland Basin Inventory terrain analysis methods.
