Water is impaired due to one or more pollutants and associated quality impacts.
Notes
This water was put on the Impaired Waters List in the 2006 cycle due to degraded habitat caused by sediment/TSS and total phosphorus. This water is part of the Rock River TMDL, approved in 2011.
Assessments in every two-year cycle from 2012 to 2024 confirmed the phosphorus impairment. Biology (bugs and fish) showed no impairment. The impairment of elevated water temperature was added during the 2018 cycle.Pollutant
