Impaired Water Notes
Squaw Creek, located within Fort McCoy in central Monroe County, flows for nearly six miles in a southwesterly direction before reaching the La Crosse River. It has a gradient of 25 feet per mile and drains a portion of Fort McCoy and a small amount of agricultural land outside the Fort. Squaw Creek is a Class I trout stream above Squaw Lake for 5.6 miles and Class II (2008 update) below Squaw Lake for 0.2 miles. The primary substrate of Squaw Creek is sand with small amounts of gravel and boulder present. In-stream cover is scarce. Stormwater runoff from the many buildings and roads centered in the Fort contribute to erosion problems in the creek. Brook trout and a variety of forage fish species make up the Squaw Creek fishery. The addition of in-stream cover would benefit the Squaw Creek fishery. Access to Squaw Creek is via Fort McCoy.
In 2006 a TMDL was developed and approved by EPA for the impaired portion of stream. The TMDL described that the dam at Squaw Lake discharges water warmed in impoundment. In 2008 the stream was reclassified from a Class III to a Class II below Squaw Lake based on earlier survey work. Surveys demonstrated adequate habitat and water quality conditions for trout from Squaw Lake downstream to the La Crosse River. However, annual stocking of legal-sized trout is required to provide trout fishing. Generally there is no carryover of trout from one year to the next. The stream is recommended for delisting in 2010.
