Mill Creek Bacteria and Pearl Lake Nutrients: TMDL Project

Minnesota's Impaired Waters and TMDLs


Mill Creek is a tributary to the Sauk River, located in the southeastern portion of the Sauk River watershed in central Minnesota. Mill Creek is impaired for Escherichia coli bacteria. Pearl Lake is a shallow, eutrophic lake approximately 750 acres in size, with a maximum depth of 18.2 feet and is impaired for Nutrient/Eutrophication Biological Indicators. Pearl Lake is also located in the Sauk River Watershed.

Local project sponsors and stakeholders are primarily the Sauk River Watershed District and Stearns County and the citizens of central Minnesota. Project is currently starting the public review of the TMDL and after addressing any comments will be sent to EPA for approval.
