This project will develop a TMDL for all impaired lakes within the Crow Wing Watershed by furthering data collection in the watershed, analysis of data, allocation calculations, and introducing outreach and stakeholder participation activities.
This project will conduct a 2017 revision of the South Fork Crow River, North Fork Crow River and Sauk River Watershed Hydrological Simulation Program FORTRAN (HSPF) models and review of the Pine River Watershed HSPF model.
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 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 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.
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.
Concern for Deer Yard and Poplar lakes centers on their current trends of decreasing water transparencies often associated with phosphorus or sediment increases. Although both lakes still meet nutrient goals, trends in Secchi depth may presage emerging issues with the state of the lakes. This has further led to questions whether the productivity of the lakes have changed over time, what the natural or historical condition of the lakes were, what the current trajectory of each lake is, and how to best set management goals.
This project will complete the Total Maximum Daily Load (TMDL) study and Watershed Restoration and Protection Strategies (WRAPS) for the Lake Superior North watershed. Two segments of the Flute Reed River are impaired for aquatic life due to elevated turbidity and total suspended solids. The lower Poplar River is also listed as impaired but significant progress has occurred in the last 10 years. A TMDL and implementation plan have been completed for the lower Poplar River impairment. All other waters meet water quality standards and will be considered for protection measures.
Minnesota Erosion Control Association (MECA) will offer three one-day training session intended to educate permittees on the requirements of the Municipal Separate Storm Sewer System (MS4) permit. The focus of these workshops will be on conducting inspections and various hot topics.
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.
This project will extend the simulation period for the Hydrological Simulation Program - FORTRAN (HSPF) models for the Grand Rapids, Brainerd, Crow Wing, Redeye, Long Prairie, Sartell, Sauk, St. Cloud, and Crow watersheds, and review and comment on the calibration.
This project will extend, calibrate, and validate watershed models using the Hydrological Simulation Program - FORTRAN (HSPF) watershed model for the Mississippi Headwaters, Leech Lake, Pine, and South Fork Crow Watersheds.
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.
