This project willl complete a final TMDL document that will be submitted to EPA for approval. Document will include Lake Osakis, Clifford Lake, Faille Lake, and Smith Lake impairments. A final technical memorandum describing the elements of the model framework and any deviations from the recommended construction methodology will be also be provided with the submission of the watershed models.
This project will complete a pollutant source identification and subwatershed information report and support the development of a Draft Restoration and Protection Plan (RAPP). It will also support the devlopment of a Implementation Plan that will identify target areas for BMP implementation for bacteria reductions.
This project will determine the magnitude and sources of pollutants in Little Rock Creek and will estimate the reductions in loadings that are needed in order for the stream reaches to support cold water fish assemblages and attain water quality standards.
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.
The goal of this project is to construct, calibrate, and validate five Hydrologic Simulation Program FORTRAN (HSPF) watershed models. The outcome will be HSPF models that can readily be used to provide information to support conventional parameter TMDLs. These models will generate predicted output timeseries for hydrology, sediment, nutrients, and dissolved oxygen which are consistent with available sets of observed data.
This project will continue HSPF watershed model construction beyond the initial framework development. The consultant will add representation of point source discharges to the model. The consultant will also compile flow data for the purposes of calibration and validation. Finally, an initial hydrologic calibration will be performed and submitted for approval.
The primary goal of this project is to examine the calibration and validation of recently extended Hydrological Simulation Program – FORTRAN (HSPF) watershed models for the Mississippi River-Headwaters, Mississippi River-Grand Rapids, Mississippi River-Brainerd, Mississippi River-Sartell, Mississippi River-St. Cloud, Leech Lake, Pine River, Crow Wing River, Long Prairie River, and Redeye River watersheds and revise the calibration.
