Lake Augusta and Sunfish Lake are deep lakes located in the Lower Mississippi River Watershed Management Organization. Both lakes are approximately 40 acres in size and surrounded by watersheds with moderate to low imperviousness. Both lakes are included on the MPCA's 303(d) list as impaired for aquatic recreation due to excessive nutrients. Lake Augusta and Sunfish Lake were included in a watershed restoration and protection strategies (WRAPS) study and total maximum daily load (TMDL) performed from 2012 to 2014.
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.
Thompson Lake is a shallow lake located in the City of West St. Paul, within the Lower Mississippi River Watershed Management Organization (LMRWMO). The 7-acre lake receives runoff from a 175-acre urban watershed that was developed in the 1950's and currently provides very little stormwater treatment. The eastern shoreline is within Thompson County Park, which features a fishing pier, event center, and miles of regionally connected trails. The west shoreline of the lake abuts the St. Croix Lutheran School.
