This project will obtain spatial and long-term pollutant load information from the Root River watershed in Southeast Minnesota. To accomplish this, the Fillmore Soil and Water Conservation District (SWCD) will assist the MPCA with water quality monitoring and annual pollutant loading calculations. Approximately 25 grab samples will be collected/site/year at 5 sites within the Root River watershed (totaling 125 grab samples/year). Annual load calculations for each site will be determined using the FLUX32 model.
This project will provide an important framework for civic and citizen engagement and communication, which will contribute to long-term public participation in surface water protection and restoration activities throughout the Pine River watershed. The civic engagement plans will be incorporated into the long term plans for the major watershed project.
This project will construct, calibrate, and validate three HSPF watershed models. The consultant will produce HSPF models that can readily be used to provide information to support conventional parameter TMDLs. The consultant will clearly demonstrate that these models generate predicted output time series for hydrology, sediment, nutrients, and dissolved oxygen which are consistent with available sets of observed data.
Phase II of this project will focus on source assessment, running watershed scenarios, Kego Lake TMDL, lake protection planning, Stressor identification and the continuation of the Civic Engagement components of the project. Information gathered in Phase II will be utilized in developing the WRAP report which will be developed in the future Phase III of the project.
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.
