Assessments and recommendations for the Watershed.

USEPA Decision Document. After a full and complete review, EPA finds that the TMDL for Waumandee Creek Watershed in Buffalo County, Wisconsin, satisfies all of the elements of an approvable TMDL. These five TMDLs for sediment address 11 impairments.

Waumandee Creek Watershed Sediment TMDL for Streams

TMDL for Sediment Impaired Streams in the Waumandee Creek Watershed - Buell Creek. This TMDL project is designed to restore water resource substrate, which In most cases, the gravel substrate is extensively covered by sand, silt, and soft organic matter preventing a suitable habitat for fish and macroinvertebrate communities. Filling-in of pools reduces the amount of available cover for juvenile and adult fish. Sedimentation of riffle areas reduces the reproductive success of fish by reducing the exposed gravel substrate necessary for appropriate spawning conditions. Sedimentation also affects macroinvertebrate biomass (fish food source) which tends to be lower in areas with predominantly sand substrate than a stream substrate with a mix of gravel, rubble, and sand.

Waumandee Creek Watershed TMDL Implementation. An Implementation Plan is needed.

The Waumandee Creek Watershed is located in Buffalo County, Wisconsin. The Waumandee Creek Watershed drains 204 square miles and is characterized by steep topography, narrow valleys and numerous streams.Surface water drains to the Mississippi River by direct runoff or via Waumandee Creek and its tributaries. Temperature and sediment impairments are found in Buell Valley Creek, Cochrane Ditch (Rose Valley), Irish Valley Creek, Jahns Valley Creek, Weiland Valley Creek. Coverage of the substrates with sediment constitutes ?an objectionable deposit? under the water quality standards criterion noted in S.NR 102.04(1) (a) cited below. The creeks are limited by excessive sediment loading and habitat unsuitable to support a coldwater fishery.
