CD 8 Subwatershed Sediment Reduction Project
Projects and Practices 2016: Laws of MN 2015 First Special Session Chapter 2, Article 7, Section 7
By addressing the 23 priority input sites and bank stabilization site, the project partners have estimated a 277.3 ton/yr reduction in sediment. The project will also reduce phosphorus discharged into the Roseau River by 277.3 lbs annually.
LOCAL LEVERAGED FUNDS
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. Under this project 21 side-water inlets, 2 grade stabilization drop structures and 325 linear feet of channel stabilization will retain soil on the landscape and keep 277.3 tons of sediment from reaching the Roseau River which is impaired due to turbidity. The project focuses on the greatest contributors of sediment identified within the subwatershed. The Roseau County SWCD and RRWD have successfully collaborated on previous projects implementing best management practices. Relying on previous project experience, local knowledge and technical abilities of SWCD and Watershed staff will ensure efficient use of public dollars to improve water quality in the Roseau River.
