Impaired Water Notes
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 and biological impairment was observed (i.e. at least one fish Index of Biotic Integrity (IBI) scored in the poor condition category). 2008 was an extreme weather year; no fIBI excursion is listed because it is not representative of average conditions.

Impaired Water Notes
This water was assessed during the 2020 listing cycle; new total phosphorus sample data overwhelmingly exceed 2020 WisCALM listing criteria for the 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). Based on the most updated information, no change in existing impaired waters listing is needed.
