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 identify and compile existing nitrate data from groundwaters and surface waters in the Lower Mississippi Basin (LMB) generally and focus on the Root River Watershed. The purpose is to investigate the quantity and quality of existing nitrate data, and to organize it for use in comprehensive watershed strategy development (including assessment, TMDL computation and identification and study of nitrate sources and delivery mechanisms).
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.
