Water is impaired due to one or more pollutants and associated quality impacts.
Notes
This water was assessed during the 2014 listing cycle; biological sample data (i.e. macroinvertebrate or fish Index of Biotic Integrity (fIBI) scores) clearly met 2014 WisCALM listing thresholds for the Fish and Aquatic Life use.

This water was assessed during the 2018 listing cycle; new total phosphorus sample data exceed 2018 WisCALM listing criteria for the Fish and Aquatic Life use, however, available biological data do not indicate impairment (i.e. no macroinvertebrate or fish Index of Biotic Integrity (IBI) scored in the "poor" condition category).
New data in 2020 confirm listing information from 2018.
