The goal of this project is to continue and finalize Hydrologic Simulation Program FORTRAN (HSPF) watershed model construction and complete the calibration/validation process. The project will add representation of point source discharges to the model, compile flow and water quality data for the purposes of calibration and validation. The end result will be an HSPF watershed model that can readily be used to provide information to support conventional parameter TMDLs.
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 construct, calibrate, a set of HSPF watershed models covering the entire area of the Lake of the Woods drainage, including the Rainy River watershed. The consultant will produce HSPF models that can readily be used to provide information to support conventional parameter TMDLs. The consultant will clearly demonstrate that these models generate predicted output timeseries for hydrology which are consistent with available sets of observed data.
This project will construct, calibrate, and validate an HSPF watershed model for the Lake of the Woods River watershed. The consultants will produce HSPF watershed models that can readily be used to provide information to support conventional parameter TMDLs. The consultants will clearly demonstrate that the models generate predicted output time series for hydrology, sediment, nutrients, and dissolved oxygen that are consistent with available sets of observed data.
This project will support construction of three watershed framework models built using the Hydrologic Simulation Program FORTRAN (HSPF). These executable models will simulate hydrology at the subbasin scale. An HSPF model will be built for each of these major watersheds: Crow Wing River, Redeye River, and Long Prairie River.
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 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.
Phase 4 of the Lake Winona Total Maximum Daily Load (TMDL) project will finalize the draft Lake Winona TMDL, dated November 2009, by completing additional data analysis, lake quality modeling, updating the TMDL report, and supporting the public involvement process.
Previous research by the St. Croix Watershed Research Station (SCWRS) has identified lake physics (temperature and oxygen) and nutrient recycling (nitrogen and phosphorus) as key drivers of lake algal blooms. SCWRS will conduct monitoring consistent with the prior research efforts by re-deploying three moored buoys to collect data throughout the 2019 ice-free season, including surface water samples. Additionally, SCWRS will deploy an in situ flourometer to measure total algae and cyanobacteria concentrations and will collect and analyze cyanobacterial toxins.
This project will address Minnesota Pollution Control Agency (MPCA), United States Environment Protection Agency (EPA), and public comments on draft Total Maximum Daily Load (TMDL) studies and Watershed Restoration and Protection Strategy (WRAPS) reports, preliminary draft TMDL studies, and public noticed TMDL studies and WRAPS reports for the Lower Red River Watershed and the Lake of the Woods Watershed and produce final versions of the TMDL studies and WRAPS reports for each watershed.
This project is for technical assistance during the Lake Winona Nutrient Total Maximum Daily Load (TMDL) public notice and revisions to the document prior to sending to the Environmental Protection Agency (EPA) for final approval.
The purpose of this contract is to establish an international watershed coordinator for the Rainy River- Lake of the Woods (RR-LOW) watershed. The coordinator will assist the Minnesota Pollution Control Agency (MPCA) in facilitating and enhancing civic engagement and public participation activities through collaboration and integration of the efforts of groups working on watershed activities at local, state/provincial, tribal, and bi-national levels.
The goal of this project is to development a Total Maximum Daily Load (TMDL) study that addresses all of the non-mercury-related impaired reaches along the Red River of the North (RRN). The TMDL study will provide an analytical and strategic foundation for recommending restoration strategies for impaired waters. This phase of the project will also include civic engagement efforts by providing water quality framework and stakeholder activities for civic/citizen engagement and communication.
Approximately 70 percent of all Minnesotans rely on groundwater as their primary source of drinking water. Wells used for drinking water must be properly sealed when removed from service to protect both public health and Minnesota’s invaluable groundwater resources. The Minnesota Department of Health protects both public health and groundwater by assuring the proper sealing of unused wells.
Clean Water funds are being provided to well owners as a 50% cost-share assistance for sealing unused public water-supply wells.
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.
This project will provide the monitoring of reaches where there are data gaps, incorporate new data and analyze relevant data, identify pollutant sources, hold a stakeholder meeting, and gather information towards the future development of a Draft Restoration (TMDL) and Protection Plan.
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.
