This project will work with the MPCA to conduct watershed pollutant load monitoring at four sites in the Chippewa River watershed and one site in the neighboring Pomme de Terre River watershed . The Chippewa River Watershed Project (CRWP) team will also aid the MPCA in measuring and comparing regional differences and long-term trends in water quality. The goal is to collect quality data and complete load calculations for the five sites using the MPCA's established protocols.
This project will complete spatial and temporal revisions of 6 Hydrologic Simulation Program FORTRAN (HSPF) models, the recalibration and validation of 7 watershed HSPF models, and the revision of the drainage network and point source representation of the Pomme de Terre HSPF model.
This project will develop the Pomme de Terre Watershed Total Maximum Daily Load (TMDL) study for the second round of the 10-year watershed approach cycle in the Pomme de Terre watershed. This phase of the project will address 4 stream impairments and 3 lake impairments and produce a draft TMDL document. A second phase may be needed as the stressor ID report identifies more stream reaches with TMDL relevant stressors.
Certain stretches of the Pomme de Terre River have been identified as impaired. This project will quantify the reductions in pollutant loading that would be necessary to bring water quality in the impaired stretches to an acceptable level. It will also identify strategies that would improve water quality in these impaired stretches. Some funds will support public input activities into the Pomme de Terre River watershed management plan.
