This water was assessed during the 2016 listing cycle; chlorophyll sample data exceed 2016 WisCALM listing thresholds for the Recreation use, however, total phosphorus data do not exceed REC thresholds. Total phosphorus and chlorophyll data do not exceed Fish and Aquatic Life thresholds.

This water was assessed during the 2018 listing cycle; new chlorophyll sample data exceeded 2018 WisCALM listing thresholds for the Recreation use. Total phosphorus data were clearly below Recreation use and Fish and Aquatic Life use listing thresholds.

Assessments during the 2020 listing cycle showed total phosphorus data were in good condition for Aquatic Life use and Recreation use according to 2020 WisCALM standards. Assessments of new chlorophyll data showed good condition for Aquatic Life use; however, Recreation use condition was unclear.
