Impaired Water Notes
Based on the total phosphorus criteria excursions and the corroborating biological assessment (poor scoring fish IBI), this water is proposed as a new listing due to the “degraded biological community” impairment caused by elevated total phosphorus concentrations.

Impaired Water Notes
This water was assessed during the 2014 listing cycle; total phosphorus sample data exceed 2014 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).

Impaired Water Notes
This water was assessed during the 2020 listing cycle; new total phosphorus sample data exceed 2020 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). Chloride and temperature data were also assessed but did not exceed 2020 WisCALM listing criteria. Based on the most updated information, no change in existing impaired waters listing is needed.
