Impaired Water - Coon Creek (Coon Creek)
Dunn County, Wisconsin
LC04
2066400
0.00 - 3.35
3.35
Water is impaired due to one or more pollutants and associated quality impacts.
Notes
This water was assessed during the 2014 listing cycle; biological impairment was observed (i.e. at least one macroinvertebrate or fish Index of Biotic Integrity (IBI) average scored in the poor condition category).
A 2007 fish survey and macroinvertebrate sample were collected at the STH 79 crossing. The fish survey found a few brook trout and mottled sculpin indicating the stream is capable of supporting some cold water species but due to the impairments described above the stream is not reaching its potential. The survey failed to document reproduction of trout. Trout collected were approximately 6 to 7 inches in length and may have migrated from other streams in the watershed. Surveys were planned at CTH J but due to the lack of water the surveys were cancelled. Water was observed but very minimal. A fish survey was attempted at 390th Street (between STH 79 and CTH J) but not completed due to poor shocking efficiency. The channel was overgrow with reed canary grass and substrate consisted of silt. The stream channel was historically ditched and crops are grown up to the streambanks.

This water is covered by a restoration plan: A Water Quality Strategy for the Land and Waters of the Red Cedar River Basin (expires 2026).

Impaired Water Notes
Impairment reach is approximately from the mouth upstream to headwaters between CTH J and CTH F. In August 2007, streamflow at CTH J was very minimal and little water was observed in the channel due to summer drought conditions.
Runoff from surrounding cropland, old channelization, pasture and some barnyard runoff. In lower reaches pasture and cropland are near the stream bank. In some areas, cattle are fenced from the stream but buffer is extremely narrow. In middle reaches cropland is up to the stream bank on moderately steep slopes. Old channelization is apparent, especially in middle stream reaches.
