Notes
This water was assessed during the 2016 listing cycle; biological sample data (i.e. macroinvertebrate or fish Index of Biotic Integrity (IBI) scores) clearly met 2016 WisCALM listing thresholds for the Fish and Aquatic Life use.

This water was assessed during the 2018 listing cycle; new biological (fish Index of Biotic Integrity (IBI) scores) sample data were clearly below 2018 WisCALM listing thresholds for the Fish and Aquatic Life use.

Assessments during the 2020 listing cycle showed total phosphorus levels too high for healthy aquatic communities like plants, fish, and bugs. Fish and bug sample data also showed poor condition. This water was proposed for the impaired water list in 2020.
