Green County, Wisconsin
SP11
877700
0.00 - 1.68
1.68
Water is impaired due to one or more pollutants and associated quality impacts.
Notes
North Fork Juda Branch is impaired by low dissolved oxygen due to biochemical oxygen demand (BOD) and total phosphorus. It was added to the Impaired Waters List during the 1998 cycle. Evaluations every two-year cycle from 2014 to 2024 confirmed the elevated phosphorus levels.

Impaired Water Notes
This water was assessed during the 2014 listing cycle; total phosphorus sample data overwhelmingly exceed 2014 WisCALM listing criteria for the Fish and Aquatic Life use and biological impairment was observed (i.e. at least one macroinvertebrate or fish Index of Biotic Integrity (IBI) scored in the poor condition category).
Date

Impaired Water Notes
This water was assessed during the 2016 listing cycle; total phosphorus sample data overwhelmingly exceeded 2016 WisCALM listing criteria for the Fish and Aquatic Life use and biological impairment was observed (i.e. at least one macroinvertebrate or fish Index of Biotic Integrity (IBI) scored in the poor condition category).
Date
9/9/2015

Impaired Water Notes
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, however, no new biological data (i.e. macroinvertebrate or fish Index of Biotic Integrity (IBI) already scored in previous water evaluation cycles) were available to assess further 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 and biological impairment was observed (i.e. at least one macroinvertebrate and fish Index of Biotic Integrity (IBI) scored in the poor condition category).
Date

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.
