Impaired Water - Token Creek (Token Creek)
Dane County, Wisconsin
2.95 - 3.44
Water is impaired due to one or more pollutants and associated quality impacts.
This segment of Token Creek was placed on the impaired waters list in 1998 for sediment and degraded biological communities. A TMDL for this pollutant-impairment combination was approved in 2002.
This segment of Token Creek was evaluated in the 2022 cycle for phosphorus and biology; no impairment was found.

Impaired Water Notes
Token Creek originates in the township of Windsor (T9N, R10E, Sec. 24) and flows 10 miles south to Cherokee Marsh. There are four segments to the stream, with two segments on the 303(d) list as described below.
Highway 51 to Dam (mile 2 to mile 4)
The designated use of this two-mile segment that of a coldwater fishery.
Presently, the stream�s existing use is a coldwater class III. However, it has the potential to be class I or II coldwater fishery and the present fishery is more indicative of a warmwater fishery. Habitat impairments are due to �soft sediment� covering the native substrate. Macroinvertebrates tend to be tolerant species. Low numbers of trout have been found in this stream. From information on page 2-14 of the Lake Mendota Priority Watershed Plan, this segment of Token Creek is �characterized by moderate velocities, high turbidity, heavy sedimentation, natural occurring log jams, overall channel widening and heavy in-stream aquatic plant growth�. It is presumed that the high turbidity will be addressed through the control of sediment sources identified in the load allocation section of this TMDL. Temperature may have been a concern is the impoundment. However, with the removal of the dam, temperature should not be a concern.
