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.
TMDL project in the Root River Watershed that will support surface water assessment, analysis of data, interpretation of southeast Minnesota's karst landscape, stressor identification, TMDL computation, source assessment, and implementation planning.
The goal of this project is to investigate nitrate transport and the sources of nitrate in karst for more effective implementation of best management practices that will reduce nitrate concentrations in ground and surface water.
