This project will complete spatial and temporal revisions , recalibration and validation of 7 watershed HSPF models. These fully functioning calibrated validated executable models will simulate hydrology, sediment (sand, silt, and clay), temperature, phosphorus, nitrogen, dissolved oxygen, biochemical oxygen demand, and algae at the 12-digit HUC subbasin scale (or finer).
The goal of this project is to extend the existing HSPF models through 2012 in the Chippewa Watershed (07020005) and Hawk-Yellow Medicine Watershed (07020004) to incorporate recent monitoring data to support current MPCA business needs and sediment source investigations.
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 Minnesota River Basin Hydrological Simulation Program FORTRAN (HSPF) models simulate sediment erosion and transport, however these models periodically need to be adjusted to be consistent with the most recent sources of information regarding sediment distribution and loading rates. The goal of this project is to refine the sediment source partitioning and simulation in the Minnesota River basin using all relevant available sources of information.
The Minnesota River Basin Hydrological Simulation Program FORTRAN (HSPF) models, which simulate flow and pollutant transport, need to be refined to be consistent with the most recent external sources of land use, hydrologic response, and surface flow attributions. The primary goal of this work is to refine the hydrologic calibration in the Minnesota River basin.
This project addresses twelve lakes that have aquatic recreation impairments as identified by eutrophication indicators and 53 impairments on 45 stream reaches in the Minnesota River Mankato and Watonwan River watersheds. The project will develop Total Maximum Daily Loads (TMDLs) addressing impaired lakes and streams in the Minnesota River–Mankato and Watonwan River watersheds. A TMDL establishes the maximum amount of a pollutant allowed in a waterbody and serves as the starting point or planning tool for restoring water quality.
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.
