Impaired Water - Unnamed (Joos Valley Creek)
Buffalo County, Wisconsin
0.00 - 7.44
Condition has improved over time; water is not impaired.
Joos Valley Creek was included in the Waumandee Creek Priority Watershed project area where several types of management practices were implemented, including manure storage facilities, livestock crossings, and streambank fencing and stabilization. These practices resulted in a statistically significant reduction in suspended solids concentrations and increase in habitat condition. A total suspended solids (TSS) Total Maximum Daily Load (TMDL) report was approved by EPA in 2003 that addresses the degraded habitat impairment. Post-implementation assessment reports document recovery of this stream's habitat quality (Wang, Lyons, and Kanehl, 2002) and decreased TSS concentrations (USGS, unpublished draft).
This water was assessed during the 2014 listing cycle; phosphorus sample data nearly met (May Meet) 2014 WisCALM listing thresholds for the Fish and Aquatic Life use and biological sample data, macroinvertebrate or fish Index of Biotic Integrity (IBI), scored in the fair to excellent condition categories. Due to restored habitat and aquatic life conditions, this water was delisted from the impaired waters list in 2012.

Impaired Water Notes
This stream is proposed for delisting from the impaired waters list. The stream is currently in Category 4a (water is impaired, and has an EPA-approved TMDL), and DNR proposes to place in Category 2 (available information indicates that one or more designated uses are met) because new data indicate that the water is now attaining water quality standards. TSS concentrations measured after implementation of management practices were found to be significantly less than pre-implementation concentrations (see attached USGS report, unpublished draft). In addition, statistically significant improvements in stream habitat condition were observed after installation of riparian management practices (Wang, Lyons and Kanehl, 2002).
