Impaired Water - Fox River (Lower Fox River (Mouth To Depere Dam))
Brown County, Wisconsin
LF01
117900
0.00 - 7.39
7.39
Water is impaired due to one or more pollutants and associated quality impacts.
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
Suspended solids loading into the AOC and Green Bay have also been estimated through monitoring (SDATF, 2002) and modeling (Baumgart, 2005). The average monitoring SS load at the mouth of the Fox River for water years 1995-1999 was 119,400 mt/yr-1 (Table 2b). This amounts to 327 metric tons per day in an average year. With the addition of the point sources, the estimated contribution from Lake Winnebago, and the estimated autogenic solids contribution from the river (WDNR, 2001), the simulated 1989-2000 suspended sediment load at the Fox River outlet to Green Bay is 119,000 mt/yr-1 (Baumgart, 2005).
This water was assessed during the 2014 listing cycle; total phosphorus sample data exceed 2014 WisCALM listing criteria for the Fish and Aquatic Life use, however, no biological data (i.e. no macroinvertebrate or fish Index of Biotic Integrity (IBI) scores) were available to assess biological impairment).
