This water was assessed during the 2016 listing cycle; chloride sample data clearly met 2016 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). Available chloride sample data were assessed, but clearly met (did not exceed) 2018 WisCALM listing criteria for the Fish and Aquatic Life use.Pollutant
