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. New macroinvertebrate sample data and existing fish sample data were assessed, but no macroinvertebrate or fish Index of Biotic Integrity (IBI) scored in the "poor" condition category.Pollutant
