This project will maximize the utility and usefulness of three HSPF models that have been constructed and calibrated for hydrology. The contractor will identify and reduce parameterization errors in the following three HSPF models: 1) Buffalo River Watershed, 2 ) Thief River Watershed, 3) Bois de Sioux-Mustinka Watersheds. This will result, not only in a better hydrology calibration, but will also improve each of the models’ ability to more accurately estimate sediment and pollutant loads and concentrations.
This project will complete the development of two watershed HSPF models for the Mustinka River and Bois de Sioux River watersheds. These calibrated and validated executable models will simulate hydrology at the 12-digit HUC subbasin scale.
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 finalize the Hydrologic Simulation Program FORTRAN (HSPF) watershed model construction and complete the calibration/validation process. The consultant will produce an HSPF watershed model that can readily be used to provide information to support conventional parameter TMDLs. The consultant will clearly demonstrate that this model generates predicted output timeseries for hydrology, sediment, nutrients, and dissolved oxygen which are consistent with available sets of observed data.
This project will address United States Environmental Protection Agency (USEPA) comments on the Preliminary Draft Total Maximum Daily Load (TMDL) study and Minnesota Pollution Control Agency (MPCA) comments on the pre-public notice draft Watershed Restoration & Protection Strategy (WRAPS) report, and produce Public Notice Draft TMDL study and Public Notice Draft WRAPS report ready for public review and comment.
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.
This project will develop the Pomme de Terre Watershed Total Maximum Daily Load (TMDL) study for the second round of the 10-year watershed approach cycle in the Pomme de Terre watershed. This phase of the project will address 4 stream impairments and 3 lake impairments and produce a draft TMDL document. A second phase may be needed as the stressor ID report identifies more stream reaches with TMDL relevant stressors.
This project will establish a framework with the Pomme de Terre River Association (PDTRA), county staff, Soil and Water Conservation District staff, and state agencies that will outline their involvement throughout the development of the Watershed Restoration and Protection Strategy (WRAPS) for the Pomme de Terre River watershed. This work will form the basis to establish restoration and protection strategies that local governments and watershed organizations can use to make decisions that will lead to protecting and restoring the waters in the watershed.
The goal of this project is to extend through 2016, calibrate, and validate the existing watershed model using Hydrological Simulation Program FORTRAN (HSPF) for the Pomme de Terre River Watershed. The contractor will produce an HSPF model that can readily be used to provide information to support conventional parameter Total Maximum Daily Load (TMDL) studies.
