Water is impaired due to one or more pollutants and associated quality impacts.
Notes
This segment of South Branch Manitowoc River was put on the Impaired Waters List for PCB contaminated sediment and fish tissue in the 1998 cycle. In the 2012 cycle high phosphorus was identified as an additional pollutant. In the 2016 it was also listed for elevated water temperature.

Evaluations every two-year cycle from 2012 to 2020 confirmed the phosphorus listing.
