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.
The goal of this project is to refine the nutrient and algae simulation in the Minnesota River basin using all relevant available sources of information. The outcome of this work order is a revised Hydrological Simulation Program – FORTRAN (HSPF) watershed model application for the Minnesota River basin that correctly represents nutrient sources and algae.
