This water was assessed during the 2018 listing cycle; temperature sample data clearly 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).
