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 Statewide Sediment Network was established to measure the levels of suspended sediment concentrations and particle size distributions at eight sites across Minnesota to evaluate the amount of sediment carried by rivers. USGS sample collection and laboratory analysis techniques provide a more rigorous, robust, and technically accurate measure of sediment in water than the current use of total suspended solids as the measure of sediment in water.
