This project addresses twelve lakes that have aquatic recreation impairments as identified by eutrophication indicators and 53 impairments on 45 stream reaches in the Minnesota River Mankato and Watonwan River watersheds. The project will develop Total Maximum Daily Loads (TMDLs) addressing impaired lakes and streams in the Minnesota River–Mankato and Watonwan River watersheds. A TMDL establishes the maximum amount of a pollutant allowed in a waterbody and serves as the starting point or planning tool for restoring water quality.
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 collect water samples at seventeen monitoring locations ranging in size from 23,173 acres (7 Mile Creek) to over 9 million acres (Minnesota River at St. Peter) as a part of the Watershed Pollutant Load Monitoring Network (WPLMN). The Minnesota State University - Water Resources Center (WRC) has been directly involved with the program and is familiar with the streams and hydrology of the region. In addition to monitoring, the WRC will review, manage and submit the data in formats provided by the Minnesota Pollution Control Agency (MPCA).
