This project is to develop a watershed restoration and protection strategies report that provides quantitative pollutant source estimates and a set of pollutant reduction and watershed management strategies to protect and achieve water quality standards for all aquatic life and aquatic recreation impairments in the watershed. The strategies will be understood and adoptable by local units of government and other stakeholders. New understandings and new relationships will inform and lead to eventual environmental improvements.
This project is the continuation of efforts to restore and protect watersheds and streams in Minnesota’s Lake Superior coastal region. The project provides the means to evaluate water quality impairments, complete pollutant source assessments, establish loading capacities and allocations for impairments, and to evaluate and recommend protection strategies for high quality water resources. It also leverages and encourages adoption of locally driven solutions to watershed management and protection.
This project will respond to public notice comments received after a 2nd comment opportunity and several requests for changes to the Total Maximum Daily Load (TMDL) report and petition for contested case hearings (CCH). Additional review work must be completed and if necessary, edits or updates to the TMDL and Watershed Restoration and Protection Strategy (WRAPS) reports. If there are substantial changes to both documents another public noticing will be necessary.
Four beaches along the North Shore of Lake Superior and within the Duluth Harbor have aquatic recreation impairments due to high concentrations of E. coli, a bacterial indicator of fecal contamination. The project area includes portions of the Lake Superior South and St. Louis River watersheds near Duluth. Several of the beaches are also listed as impaired for beneficial use (due to fecal bacteria) as part of the St. Louis River Area of Concern.
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 three HSPF watershed models. The project will result in HSPF models that can readily be used to provide information to support conventional parameter TMDLs. The models are expected to generate predicted output timeseries for hydrology, sediment, nutrients, and dissolved oxygen which are consistent with available sets of observed data.
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.
The goal of this project is to construct, calibrate, and validate two Hydrologic Simulation Program FORTRAN (HSPF) watershed models: Lake Superior North and Lake Superior -South. The contractor will produce HSPF models that can readily be used to provide information to support conventional parameter Total Maximum Daily Loads (TMDLs). The contractor will clearly demonstrate that these models generate predicted output timeseries for hydrology, sediment, nutrients, and dissolved oxygen which are consistent with available sets of observed data.
The goal of this project is to continue and finalize Hydrological Simulation Program FORTRAN (HSPF) watershed model construction and complete the calibration/validation process. The consultants will produce HSPF watershed model applications for the Lake Superior North and Lake Superior South watersheds that can readily be used to provide information to support conventional parameter Total Maximum Daily Load (TMDL) projects.
The goal of this project is to extend, calibrate, and validate the existing Hydrological Simulation Program – FORTRAN (HSPF) watershed models in the Red Lake River, Thief River, Clearwater River and Red Lake watersheds.
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.
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.
