Description
The Crystal Loon Mills Lakes (CLM) watershed is located in the Middle Minnesota River Basin,
in south central Minnesota. Crystal Lake is 355 acres with a contributing watershed of
approximately 14,000 acres. The watershed has significant local importance, as it is a popular
recreational resource and contains the City of Lake Crystal. In 2006, Crystal Lake was listed on the 303d impaired waters list for excess nutrients. In the fall of 2004, Crystal Lake experienced a toxic algae bloom. Minnesota Pollution Control Agency (MPCA) staff reported a concentration of microcystin, a blue-green algae toxin, at 7190 ug/L.
The World Health Organization’s provisional drinking water guideline value for microcystin is 1.0 ug/L and a range of 1-10 ug/L is recommended for recreational exposure. The TMDL program provides a cooperative approach with MPCA assisting the Water Resources Center-Minnesota State University Mankato (WRC-MSUM) and the City of Lake Crystal in data collection, analysis and TMDL development. Following completion of a TMDL study and implementation planning, TMDL implementation funds will be available to the City of Lake Crystal, Blue Earth County, and other entities on a competitive basis.
