Water is impaired due to one or more pollutants and associated quality impacts.
Notes
Neenah Slough is on the 303(d) list for total phosphorus which causes low dissolved oxygen, and PCBs which contaminates fish tissue. This water is part of the Lower Fox River TP & TSS TMDL that was approved by the EPA in 2012. This water was evaluated in 2020 for bugs and fish communities; the fish community was in poor health.Pollutant

Impaired Water Notes
The Lower Fox River Basin TP and TSS TMDL was approved by the U.S. EPA on May 18, 2012. The TMDL covers 27 waterbody segments impaired by total phosphorus and 18 waterbodies impaired by TSS for a total of 45 TMDLs. These TMDLs address degraded habitat, low Dissolved Oxygen (DO), eutrophication, and turbidity impairments.

Impaired Water Notes
This water was assessed during the 2020 listing cycle; new total phosphorus sample data exceed 2020 WisCALM listing criteria for the Fish and Aquatic Life use and biological impairment was observed (i.e. at least one fish Index of Biotic Integrity (IBI) scored in the poor condition category).
