Long and Ringo Lakes - Excess Nutrients: TMDL Project

Minnesota's Impaired Waters and TMDLs


Long Lake was placed on the 303(d) list in 2002, and Ringo Lake was added in 2010, both being impaired for the designated use of aquatic recreation due to excess nutrients. Long Lake is 1,612 acres and has a maximum depth of 16 feet. The Long Lake watershed is approximately 8,300 acres. The majority of the watershed is to the northeast of the lake. The inlet to the lake flows from Ringo Lake (a 774-acre lake to the north) through a wetland and into the lake. Long and Ringo Lake’s watersheds are made up of a mix of cultivated lands, Conservation Reserve Program (CRP), urban/residential, wooded areas, wetland, and lakes. 

The Hawk Creek Watershed Project is funded through Clean Water Partnership (CWP).
