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 extend existing Hydrologic Simulation Program FORTRAN (HSPF) models through 2017 for the following major watersheds: Redwood, Cottonwood, Watonwan, Blue Earth, Le Sueur, Pomme de Terre, Minnesota River-Headwaters, and Lac Qui Parle watersheds.
This project will update sediment Total Maximum Daily Loads (TMDLs) for 60-64 impaired stream reaches and provide a final TMDL report. The report will address sediment and turbidity impaired streams in the Minnesota River Watershed. TMDLs will describe the impairment in each water body and water quality targets, and will include a discussion of pollutant sources, supporting report components that document assumptions and methodologies, and TMDL equations with completed load allocations, wasteload allocations, and margin of safety for each impairment.
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.
The goal of this project is the continued development of an overall strategy for reduction of turbidity/TSS, with sets of sediment reduction initiatives and actions for various sources, to address the Minnesota River Turbidity TMDL and the South Metro Mississippi River TSS TMDL. The overall strategy will be used to help establish a path towards achieving the required reductions of turbidity/TSS.
