Water is impaired due to one or more pollutants and associated quality impacts.
Notes
This water was assessed during the 2014 listing cycle; phosphorus sample data nearly exceeded (May Exceed) 2014 WisCALM listing thresholds for the Fish and Aquatic Life use, but biological sample data, macroinvertebrate or fish Index of Biotic Integrity (IBI), scored in the fair to excellent condition categories. Further monitoring is recommended.
This water was assessed during the 2018 listing cycle; new total phosphorus sample data may 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).
This water was added to the Impaired list during the 2026 cycle as new data suggested total phosphorus levels clearly exceed attainment standards.Pollutant
