Impaired Water - Fox River (Fox River)
Waukesha County, Wisconsin
FX07
742500
113.99 - 121.06
7.07
Water is impaired due to one or more pollutants and associated quality impacts.
Notes
This segment of the Fox River was put on the 303d list due to total suspended solids, total phosphorus, and PCBs in the 1998 cycle.

This segment of the Fox River was evaluated every two-year cycle from 2014 to 2022; elevated phosphorus was confirmed in the 2014 and 2016 cycles. Chloride and bug data indicated good conditions.

Impaired Water Notes
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, available biological data do not indicate impairment (i.e. no macroinvertebrate or fish Index of Biotic Integrity (IBI) scored in the "poor" condition category).
Date

Impaired Water Notes
This water was assessed during the 2016 listing cycle; total phosphorus sample data exceed 2016 WisCALM listing criteria for the Fish and Aquatic Life use, however, available 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
The Barstow Impoundment is centrally located in downtown Waukesha. The impoundment itself, along with other areas upstream, are on the Federal 303(d) list of impaired waters. Sediment has collected and been concentrated behind the dam. The impoundment has seen an increased use by the public in the recent years with public recreation, boating, park access, and subsistence fishing. The Badgerland Ski Team hold scheduled practices and shows all summer within the impoundment. There is concern with the possible pollutant load in fish and sediment in this area. With such an increased use along this stretch of river, it is important to identify any possible sources of health risks to the public. There is a large sediment buildup behind dam and throughout the impoundment. It is a concern that this sediment is becoming suspended and translocating downstream from multiple sources. Previous sediment sampling indicated sediment toxicity issues. Follow-up sampling, including macroinvertebtrate and fish community sampling, will assist in clarifying the accuracy of the 303(d) listing and documenting impacts to the waterbody and to public health. The follow-up conclusions will also update the fish consumption advisory. From Hudak, Monitoring Proposal 2007
