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.
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.
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.
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.
