Water is impaired due to one or more pollutants and associated quality impacts.
Notes
This segment of Pheasant Branch has been on the state's 303(d) impaired waters list since 1998. This water was assessed during the 2012 listing cycle, and total phosphorus sample data exceed 2012 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). The TMDL is now approved.

This water was assessed during the 2016 listing cycle and chloride sample data exceeded 2016 WisCALM chronic listing criteria for the Fish and Aquatic Life use.

This water was assessed during the 2018 listing cycle; new total phosphorus and chloride sample data exceeded 2018 WisCALM listing criteria for the Fish and Aquatic Life use, however, available biological data did not indicate impairment (i.e. no macroinvertebrate or fish Index of Biotic Integrity (IBI) scored in the "poor" condition category). New temperature sample data were clearly below 2018 WisCALM listing thresholds for the Fish and Aquatic Life use.

Assessments of new data during the 2020 listing cycle showed temperature levels appropriate for healthy aquatic communities like plants, fish, and bugs.
