Notes
This water used to have a specific advisory for PCBs. Like all waters it has a general advisory for Mercury in fish tissue.
This water was assessed during the 2014 listing cycle; total phosphorus sample data clearly met 2014 WisCALM listing thresholds for the Fish and Aquatic Life use (no biological data (i.e. no macroinvertebrate or fish Index of Biotic Integrity (IBI) scores) were available to assess biological impairment).
This water was assessed during the 2018 listing cycle; new total phosphorus, biological (macroinvertebrate and fish Index of Biotic Integrity (IBI) scores) and chloride sample data were clearly below 2018 WisCALM listing thresholds for the Fish and Aquatic Life use. New fish tissue samples indicate that a special fish consumption advisory for PCBs is no longer needed; this water is proposed for delisting in 2018.

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