Water is impaired due to one or more pollutants and associated quality impacts.
Notes
This unnamed stream was evaluated for biology every two years from 2016 to 2020 and communities appear healthy. In 2020 the stream was evaluated with phosphorus and levels were too high for sustained healthy aquatic communities like plants, bugs, and fish. A phosphorus listing was added in 2020. New water quality data reviewed in the 2024 cycle indicated no additional pollutants.Pollutant

Impaired Water Notes
This water was assessed during the 2020 listing cycle; new total phosphorus sample data overwhelmingly 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).
