Cedar Lake and McMahon (Carl's) Lake (DNR IDs 70-0091 and 70-0050, respectively) are currently listed on the Minnesota Pollution Control Agency's (MPCA) 2008 303(d) Impaired Waters List due to excessive nutrients (phosphorus). Both lakes are located in the lower portion of the Minnesota River Basin (Figure 1) and lie within the North Central Hardwood Forest Ecoregion. A Total Maximum Daily Load (TMDL) Report was completed for Cedar Lake and McMahon Lake in January 2010. The Implementation Plan for Cedar Lake and McMahon Lake is multi-faceted, with various projects put into place over the course of many years. This adaptive management approach allows for monitoring and reflection on project successes and the chance to change course if progress is exceeding expectations or is unsatisfactory. The Scott Watershed Management Organization (WMO) is taking the lead on implementing the projects described in this plan, with the support of Minnesota Pollution Control Agency and local entities within the watershed.
