Impaired Water - Fox Lake (Fox Lake)
Dodge County, Wisconsin
UR03
835800
2,713.34
Water is impaired due to one or more pollutants and associated quality impacts.
Notes
Fox Lake was evaluated for phosphorus and biology every two years from 2012 to 2020. Phosphorus levels were found to be too high, which was reflected in algal blooms. This lake is part of the Rock River TMDL restoration plan, approved in 2011.
