Notes
This water was assessed during the 2014 listing cycle; chloride sample data clearly met 2014 WisCALM listing thresholds for the Fish and Aquatic Life use. Phosphorus sample data nearly met (May Meet) 2014 WisCALM listing thresholds for the Fish and Aquatic Life use and biological sample data, macroinvertebrate or fish Index of Biotic Integrity (IBI), scored in the fair to excellent condition categories. Further monitoring may be recommended.

The upstream AU (10769) was assessed during the 2018 listing cycle; new temperature sample data 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). Based on that assessment, this segment water is being listed for elevated water temperatures as well.
