Little Rock Lake - Nutrients: TMDL project

This project addresses one lake nutrient impairment. Little Rock Lake had a bloom of blue-green algae the 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) is leading this project.
