Notes
The Killsnake River was listed for PCBs in fish tissue in 1998 but was delisted 2002.

This segment of the Killsnake River was put on the Impaired Waters List for elevated temperature in the 2016 cycle and high phosphorus levels in the 2018 cycle. Evaluations every two year cycle from 2018 to 2022 confirmed the phosphorus impairment.

Impaired Water Notes
This water was assessed during the 2018 listing cycle; new total phosphorus sample data overwhelmingly exceed 2018 WisCALM listing thresholds for the Fish and Aquatic Life use, however, no biological data (i.e. no macroinvertebrate or fish Index of Biotic Integrity (IBI) scores) were available to assess biological impairment.

Impaired Water Notes
This water was assessed during the 2020 listing cycle; new total phosphorus sample data overwhelmingly exceed 2020 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).

Impaired Water Notes
This water was assessed during the 2022 listing cycle; new total phosphorus sample data overwhelmingly exceed 2022 WisCALM listing criteria for the Fish and Aquatic Life use.
