Watershed - Elk Creek (BT03)
Elk Creek Watershed

Details

The Elk Creek Watershed lies within two counties, Buffalo and Trempealeau, and three combined basins, the Black, Buffalo, and Trempealeau River (BBT), located in West Central Wisconsin. Of the 3,852 mi2 these basins cover, the Elk Creek Watershed encompasses only 113 mi2. There are 285 miles of streams, many of which are only partially meeting their potential use because they are limited by agricultural nonpoint sources of pollution.

Population, Land Use

Watershed land use data from the 2001 National Land Cover Inventory dataset, which illustrates the domination of agriculture and forests in the watershed. Wetlands make up a considerably large component of the water resources in this watershed (3,311 acres), or 4% of the total land area, compared to lakes which cover 47 acres of the landscape. The primary land use in this watershed is agriculture (54% of the land) followed by forest, encompassing roughly 34% of the total acreage of the watershed. The communities of Elk Creek Watershed include the towns of Chimny Rock, Hale, Burnside, Lincoln and Sumner and at the outlet of the watershed is the City of Independence.

Nonpoint and Point Sources

The Elk Creek Watershed was one of the five initial priority watershed projects selected under the Wisconsin Nonpoint Source Water Pollution Abatement Program in 1979. Implementation of best management practices was administered by the DNR and the Trempealeau County Land Conservation Department from 1980 -1988. The water quality objectives of the priority watershed project were:1) Decrease sediment loading to Bugle Lake; 2) Improve Hilsenhoff Biotic Index values to excellent category for aquatic insects; 3) Reduce fecal bacterial levels; 4) Upgrade the aesthetics of streams (improve smell and appearance). The Elk Creek Priority Watershed Project was partially successful in meeting the established water resource objectives based on evaluation monitoring results. The most significant measured change was a considerable reduction in fecal coliform and fecal streptococcus bacterial levels in several of the watershed streams. Based on discussions with individuals who are familiar with the history of the Elk Creek watershed, the streams smell less offensive and look cleaner than before the project began. Although these changes may not be readily quantified, it appears the objective of cleaner and better smelling streams has been achieved to a degree.
