The goal of this project is to apply the Hydrological Simulation Program FORTRAN (HSPF) model to evaluate scenarios to support potential management actions and implementation in the watershed, construct Total Maximum Daily Load (TMDL) studies, and to develop a conceptual site model of the lakes for understanding phosphorus release.
There are two main goals of this Cedar Basin HSPF project,
A. Overall development of the HSPF model in the Cedar Basin of Minnesota; and
B. Shell Rock River nutrient, DO , impairment modeling and TMDL completion.
This project will construct, calibrate, and validate an HSPF watershed model for the Zumbro River watershed. The consultant will produce HSPF watershed models that can readily be used to provide information to support conventional parameter Total Maximum Daily Load (TMDLs). The consultant will clearly demonstrate that the models generate predicted output timeseries for hydrology, sediment, nutrients, and dissolved oxygen that are consistent with available sets of observed data.
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 consultant LimnoTech will support response to Total Maximum Daily Load (TMDL) comments the peer review process, United States Environmental Protection Agency and public notice. They will then revise the TMDL document as needed and attend internal and external project meetings.
This project will complete a Acetochlor Impairment Response Report. This report will combine and coordinate information relating to actions being done in direct response to the acetochlor water quality impairments with those being done and support MDA’s on-going responsibility to assure pesticides are used in a manner that does not cause unreasonable adverse effects on the environment.
The MPCA has selected the Soil and Water Assessment Tool (SWAT) watershed model to simulate watershed hydrology and water quality to assess various restoration scenarios in the Little Cannon River watershed. The SWAT model is an important tool in developing an understanding of existing conditions and simulating conditions under various management scenarios to inform the development of implementation strategies and plans to restore and protect streams and lakes.
