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 purpose of this project is to improve understanding of primary productivity in the Red River and the diversity and population structure of the algal communities occurring along the river system. This will be accomplished through taxonomic identification of periphyton and phytoplankton assemblages necessary for characterizing responses to nutrient gradients along the Red River of the North.
The International Water Institute (IWI) will monitor 42 sites (3 basin, 12 major watershed, and 27 subwatershed) in the Red River and Upper Mississippi River Basins intensively during 2016, 2017, 2018 and 2019. There will also be 5 sites in the Red River Basin where mercury samples will be collected in 2016 and 2017 and sent to Minnesota Department of Health for analysis. The IWI will collect water samples across the range of flow conditions targeting sample collection at times of moderate to high flow.
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.
