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 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 purpose of this project is to identify effective irrigation and nutrient management best management practices and technologies and the barriers that prevent irrigators, producers, and other agricultural partners from adopting them in Otter Tail County. The primary goal is to reduce nitrate in areas where groundwater is susceptible to contamination as mapped by The Minnesota Department of Health by identifying effective BMPs and addressing the barriers to their adoption.
As lake-focused development continues these high quality waters will see increasing amounts of land use change. The State Demographer projects that the targeted lake catchments will see population increases of 25-62% within 20 years. Isolating these contributing areas permits the Lake Protection Analysis project to perform multiple GIS analyses to accurately inform water quality discussions. The final framework will allow local water managers to prioritize across their water bodies, target activities to specific subsheds, and develop measurable goals.
The Lake Ida and Ditch 23 Wetland Feasibility Project will investigate and review the phosphorus loading of Lake Ida and design a project to protect Lake Ida water quality. Lake Ida is a 'high quality, unimpaired lake at the highest risk of becoming impaired' according to MPCA's Lakes of Phosphorus Sensitivity Significance. With the County Ditch 23 inlet identified as a priority area to reduce phosphorous, a professional engineering firm will explore the best solution to reduce phosphorus.
The Douglas County Partners for Clean Water program enables community groups to take action and improve their water resources. Engaging citizens directly in project development and installation efforts provides immediate water quality benefits and cultivates a community of active stewardship.
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 seeks to inventory twenty registered feedlots identified as having an Unpermitted Liquid Manure Storage Area. Specifically, this inventory would include offering cost-share for soils investigations. These feedlots are located in three townships that have also been identified as having groundwater that is vulnerable to nutrient pollution, necessitating a need for nitrate testing per MN Department of Agriculture. These townships also house the vast majority of remaining unpermitted Liquid Manure Storage Areas in the County.
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.
