Notes
This water was assessed during the 2016 listing cycle; general mIBI assessment indicates that this water may not meet Fish and Aquatic Life use. Further monitoring is recommended.

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

This water was assessed during the 2018 listing cycle; new total phosphorus sample data overwhelmingly exceed 2018 WisCALM listing criteria for the Fish and Aquatic Life use and biological impairment was observed. Available fish sample data were assessed; at least one fish Index of Biotic Integrity (IBI) scored in the poor condition category, however available macroinvertebrate sample data did not indicate impairment (i.e. no macroinvertebrate IBI scored in the "poor" condition category).
This water is part of the Wisconsin River TMDL.
