The Cedar Island, Pike and Eagle Lakes Excess Nutrient TMDL (Total Maximum Daily Load) is a plan developed by the Shingle Creek Watershed Management Organization to reduce phosphorus entering the lakes. The Minnesota Pollution Control Agency has identified all three lakes as impaired. The lakes do not meet state standards for their intended recreational and aesthetic uses due to excessive amounts of phosphorus.
This study establishes the amount of phosphorus each lake could take in each day and still meet state water quality standards. The implementation plan outlines steps to reduce the daily phosphorus loading to that level.
