Impaired Water Notes
This water was assessed during the 2018 listing cycle; new temperature 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 total phosphorus sample data were clearly below 2018 WisCALM listing thresholds for the Fish and Aquatic Life use.
