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.
The goal of this project is to finalize the Lake Pepin Watershed phosphorus total maximum daily load (TMDL) report by using the existing information and documentation prepared under previous contracts to prepare one TMDL report that addresses the impairments on the mainstem of the Mississippi River. Information developed to date for draft TMDLs on the Minnesota River mainstem will be documented for later use by the Minnesota Pollution Control Agency.
The Minnesota Pollution Control Agency’s (MPCA) Watershed Pollutant Load Monitoring Network (WPLMN) forms the core of a long-term program designed to measure and compare regional differences and trends in pollutant loadings from Minnesota’s mainstem rivers and the outlets of major watersheds and subwatersheds draining to these rivers.
This project will complete a chloride management plan which will lay out a strategy for addressing chloride impacts to our surface waters for the 7-county metropolitan area. This chloride management plan will satisfy EPA requirements for impaired waters, address waters not yet listed, and develop a strategy to protect waters that are currently meeting the water quality standards.
This project will provide the MPCA and all local partners in the Twin Cities Metropolitan Area (TCMA) the information and tools necessary to improve and/or maintain water quality with respect to chloride for the 7-county metropolitan area during the winter maintenace period.
