Water is impaired due to one or more pollutants and associated quality impacts.
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).

This water was assessed during the 2016 listing cycle; total phosphorus sample data exceed 2016 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).

This water was assessed during the 2018 and 2020 listing cycles; new total phosphorus and fish sample data exceed 2018 and 2020 WisCALM listing criteria for the Fish and Aquatic Life use (i.e. at least one fish Index of Biotic Integrity (IBI) average scored in the poor condition category). New temperature sample data were clearly below 2018 and 2020 WisCALM listing thresholds for the Fish and Aquatic Life use.
This water is covered by the Upper Fox & Wolf River Basins TMDL, approved by the US EPA on February 27, 2020.
