0.00 - 5.76
5.76
Water is impaired due to one or more pollutants and associated quality impacts.
Notes
TMDL has been approved 2003.
Newcomb Valley Creek in Trempealeau County, a 4.6-mile
tributary of Turton Creek, is also listed on the 303(d) list. Newcomb Valley Creek is
impacted by sedimentation, excessive total suspended solids leading to turbidity and loss
of instream habitat. The primary source of impairment is stream bank erosion. The
stream is currently classified as a Warm Water Forage Fishery, but a 1990 survey found 5
brook trout (2-8.4 inches), suggesting some natural trout reproduction in the headwaters.
The survey also found Johnny darter and logperch. The stream HBI was 3.21, indicating
no apparent organic pollution, and the Habitat Rating was "fair". The potential use of the
creek is a coldwater Class III trout fishery.
