Notes
This water was assessed during the 2016 listing cycle; total phosphorus sample data clearly met 2016 WisCALM listing thresholds for the Fish and Aquatic Life use. Biological impairment was observed (i.e. at least one macroinvertebrate or fish Index of Biotic Integrity (IBI) scored in the poor condition category), but it was insufficient for a stand-alone assessment.

This water was assessed during the 2018 listing cycle; available total phosphorus sample data were clearly below 2018 WisCALM listing thresholds for the Fish and Aquatic Life use, however, biological impairment was observed (i.e. at least one macroinvertebrate and fish Index of Biotic Integrity (IBI) scored in the poor condition category).
