Notes
The habitat of Blue River is impaired by sediment/suspended solids in the river.

This water was assessed during the 2018 listing cycle; based on 2018 WisCALM listing criteria for the Fish and Aquatic Life use, available biological data did not indicate impairment (i.e. no macroinvertebrate or fish Index of Biotic Integrity (IBI) scored in the "poor" condition category). Further biological monitoring is recommended.

Assessments during the 2020 listing cycle showed new fish sample data were in poor condition.
