TMDL Development for Squaw Creek
and Stillwell Creek, Monroe County, WI. Stillwell Creek is a 4.7-mile trout stream with a gradient of 28 feet per mile that drains an area of
approximately five square miles. A 2.2-mile segment downstream from the cranberry operation supports
a class III trout fishery whereas the segment upstream of the cranberry operation is classified as a class II
trout fishery. The segment of the creek downstream of the cranberry operation is considered impaired
because the fish community is rated poor as measured using the Index of Biotic Integrity (IBI). The low
IBI scores are believed to be due to high temperatures, and degraded habitat which is reflected in an
elevated fine sediment count.
TMDL (USEPA) Approved
EPA initiated and approved TMDL for Squaw Creek and Stillwell Creek, Monroe County, WI. The Wisconsin Department of Natural Resources (WDNR) listed Squaw Creek due to temperature
impairments. WDNR listed Stillwell Creek due to temperature and sediment impairments.
TMDL (USEPA) Approved
This is a U.S. EPA initiated and approved TMDL. Squaw Creek and Stillwell Creek are tributary streams of the Upper La Crosse River Basin, located in Monroe County in west-central Wisconsin. The streams are within the boundaries of Fort McCoy, a federal military facility. Both Squaw Creek and Stillwell Creek are classified as ?water quality-limited? and have been placed on Wisconsin?s list of water bodies in need of restoration, a list prepared in accordance with Section 303(d) of the Clean Water Act and known as the ?303(d) list.? The Wisconsin Department of Natural Resources (WDNR) listed Squaw Creek due to temperature impairments. WDNR listed Stillwell Creek due to temperature and sediment impairments. Stillwell Creek was added to the 303(d) list in 2003, but there was an error in listing the precise segment of the creek. The State of Wisconsin has since provided information to USEPA to correct this information.
