Contractor assistance with site selection, reconnaissance and obtaining access for installation of ambient groundwater monitoring wells in Ramsey county and Hennepin county. This project will provide services and oversight of the installation for up to 16 well sites.
Contractor assistance with site selection, reconnaissance and obtaining access for installation of ambient groundwater monitoring wells in northcentral and northeastern Minnesota. This project will provide services and oversight of the installation for up to 31 well sites.
This project will continue to develop, and calibrate/validate the hydrology of an Hydrological Simulation Program FORTRAN (HSPF) watershed model for the Buffalo River watershed. The consultant will add representation of point source discharges to the model. The consultant will compile flow data for the purposes of calibration and validation. An initial hydrologic calibration will be performed and submitted for approval.
This first year of the project will collect available data relevant to the TMDL development, determine the data sets best suited for the TMDL development. Gain a better understanding of the watershed and impaired lakes, and assessment of all potential sources (internal and external) of the causes of lake impairment. EOR will also review the data produced by the MPCA for the impairment assessment for each of the lakes during year 1 of the project.
This project will construct three watershed framework models built using the Hydrologic Simulation Program FORTRAN. These executable models will simulate hydrology at the 12-digit HUC subbasin scale. An HSPF model will be built for each of the following 8-HUC watersheds: Red Lake River (09020303) and the Clearwater River (09020305).
This project will finalize HSPF watershed model construction by incorporating internal phosphorus loading in modeled lakes, run a suite of implementation scenarios and generate a GenScn project containing model output. The consultant will produce HSPF watershed models that can readily be used to provide information to support conventional parameter TMDLs. The consultant will deliver all modeling files for baseline and implementation scenarios and provide a GenScn project containing model output.
This project will develop and execute three point source related scenarios for the Chippewa River watershed using an existing HSPF watershed model. This project will also support the review of the HSPF Modeling Guidance Document.
This project will continue to develop, and calibrate/validate the hydrology of an HSPF watershed model for the Thief River watershed. The consultant will add representation of point source discharges to the model. The consultant will compile flow data for the purposes of calibration and validation. An initial hydrologic calibration will be performed and submitted for approval. The consultant will produce an HSPF watershed model that can readily be used to provide information to support conventional parameter TMDLs.
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.
This project will complete a guidance document for the construction of Hydrologic Simulation Program FORTRAN (HSPF) watershed models which are intended to support MPCA Watershed programmatic activities. It will also customize and populate a national HSPF parameter database with values from Minnesota HSPF model applications. This enhanced database will expedite the future construction of HSPF models as well as increase the consistency among HSPF model applications in Minnesota.
This project will complete the final Implementation Plan, semi-annual and final reports and hold project meetings. The Implementation Plan will identify target areas and priorities for implementation strategies to improve water quality for Bluff Creek. This project will build the groundwork so Bluff Creek will meet water quality standards for aquatic life in the future.
This phase of the project will complete a TMDL for the impaired reaches of the Snake River Basin. The project includes development of a Unit Area Load model for nutrient sources, a spreadsheet version of a BATHTUB lake response for four lakes, and a bacteria source assessment. Contractor will also provide all stream channel data as a spreadsheet database and in GIS.
This project will complete a chloride management plan which will lay out a strategy for addressing chloride impacts to our surface waters for the 7-county metropolitan area. This chloride management plan will satisfy EPA requirements for impaired waters, address waters not yet listed, and develop a strategy to protect waters that are currently meeting the water quality standards.
