Minnesota's Impaired Waters and TMDLs
TMDL Project: Little Rock Lake — Nutrients
Background
This project addresses one lake nutrient impairment. Little Rock Lake had a bloom of blue-green algae this past summer of 2007. MPCA staff conducted air and water quality monitoring during the bloom. Algal toxin (microcystin) samples collected were determined to be a “high health risk” level according to World Health Organization standards. Due to severity of the algae bloom, Little Rock Lake was put on the draft 2008 Impaired Waters List. The Benton County Soil and Water Conservation District (SWCD) are leading this project.
Map and location
Little Rock Lake is located in the Mississippi River- Sartell watershed, which lies in the southeastern portion of the Upper Mississippi basin.
