Notes
Lake Waubesa was evaluated for phosphorus and algae every two years between 2012 and 2024. Phosphorus levels were found to be too high, which was reflected in algal blooms. This lake is covered by the Rock River TMDL restoration plan, approved in 2011.
Recent sampling by the Wisconsin Department of Natural Resources shows elevated PFOS in fish tissue.Pollutant
