Impaired Water - Fox River (Lower Fox River (Depere Dam To Middle Appleton Dam))

Water is impaired due to one or more pollutants and associated quality impacts.
Notes
Appleton to Little Rapids Reach:
Sediment accumulation in the Appleton to Little Rapids Reach is more localized compared with the other three reaches. Deposits I through DD contain about 94 kg (207 pounds) of PCBs in about 184,790 m3 ( 241,700 yd3) of sediment with concentrations greater than 50 ?g/kg PCB.

Little Rapids to De Pere Reach:
Sediment accumulation in this reach extends over a long distance and large area. Deposits EE through HH contain 980 kg (2,160 pounds) of PCBs in approximately 1.71 million m3 (2.24 million yd3) of sediment with concentrations greater than 50 ?g/kg PCB. The four deposits in this reach are essentially a single sediment unit.

This water was assessed during the 2014 listing cycle; phosphorus sample data nearly exceeded (May Exceed) 2014 WisCALM listing thresholds for the Fish and Aquatic Life use.

This water was assessed during the 2016 listing cycle; total phosphorus sample data 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).

This water was assessed during the 2018 listing cycle; new total phosphorus sample data may exceed 2018 WisCALM listing criteria for the Fish and Aquatic Life use, however, available and 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
“As many as 360 different chemicals have been found in the water, sediments, fish and wildlife of the Lower Fox River. These chemicals include PCBs, dioxins, furans, mercury, ammonia, DDT and other pesticides (see table on page 6 for more information on these chemicals). The Lower Fox River, which flows northeast for about 39 miles from Lake Winnebago at Neenah-Menasha to the river’s mouth at Green Bay, contributes more PCBs to Green Bay and Lake Michigan than any other source.... An estimated 63,000 pounds of the PCBs previously discharged remain in the Lower Fox River. Most of them are downstream of the De Pere dam. An even larger quantity has passed through the Lower Fox River to Green Bay, Lake Michigan and beyond. Results of the intensive “Mass Balance” study conducted by the DNR and EPA in 1989 showed that about 160,000 pounds of PCBs have already found their way into Green Bay from the Lower Fox. It also showed that about 620 pounds of PCBs enter the bay from the river each year.” p. 2 & Figures below p. 4 & 5

Impaired Water Notes
According to the WDNR 303 (d) list, the water quality of Lower Green Bay and the Fox River is impaired due to phosphorus and PCBs (WDNR, 2005). Phosphorus and TSS are the pollutants of concern for this framework. Even though suspended solids are not listed as a pollutant that impairs designated uses for the lower Fox River and the bay, ample research demonstrates that both TSS and phosphorous affect water quality (Harris, 1993; Millard & Sager, 1994). p. 18

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.
