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 Olmsted County Soil and Water Conservation District will assist the Minnesota Pollution Control Agency (MPCA) with water quality monitoring and pollutant load calculations at four sub-watershed sites in the Zumbro River Watershed. Approximately 25 grab samples per site between ice-out and October 31 of 2019 will be collected along with field measurements and observations. Samples will be collected using procedures described in the Watershed Pollutant Load Monitoring Network (WPLMN) Standard Operating Procedures and Guidance (SOPG).
