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.
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.
The Roseau River Watershed Assessment will include the waters of the Roseau River, Sprague Creek, Hay Creek and Hayes Lake. All of the monitoring sites, except one, are located in Roseau County, with the exception being located in Kittson County. This assessment focuses on collection of water chemistry and field parameters at one site on Hayes Lake and seven key sites on the Roseau River, which have been identified by MPCA. These sites are located in the lower reaches of each surface water system.
The Roseau River Watershed District in partnership with the Roseau County SWCD will complete a study to target and prioritize sites contributing impairments within legal drainage systems. Project partners will utilize data developed by the International Water Institute (IWI) Water Quality Decision Support Application that establishes multivariate scoring of each site based on all relevant features contributing to surface water degradation.
This is a joint project between the United States Geological Survey (USGS), Minnesota Pollution Control Agency (MPCA), North Dakota, and Manitoba. The project is a basin-wide, up-to-date water quality trend analysis using the "QWTrend" program for approximately 40 bi-national river sites to review nutrients, total suspended solids, total dissolved solids, sulfate and chloride from 1980 - 2015.
