Tamarack Creek ILF Site
The Wisconsin Wetland Conservation Trust (WWCT) proposes to construct the Tamarack Creek In-Lieu Fee (ILF) site in the Town of Trempealeau.

Tamarack Creek Wetland Bank
The Tamarack Creek Mitigation Bank Site is a proposed wetland compensatory mitigation bank in the Town of Trempealeau, Trempealeau County, Wisconsin. The project site is approximately 48.26 acres located within the Upper Mississippi-Black-Root Bank Service Area (BSA). The site is currently used for hay production on agriculturally drained wetland and is bisected by a network of drainage ditches and subsurface tile. The site contains approximately 46.03 acres of field-delineated wetland, predominantly degraded wet meadow dominated by invasive reed canary grass, with a small wooded swamp community along Tamarack Creek in the western portion of the site. The objective of the project is to restore wetland habitat and improve wetland functions by filling approximately 4,616 linear feet of interior drainage ditches, disabling subsurface drain tile, controlling invasive species, and re-establishing native wet meadow and wooded swamp plant communities. The project is anticipated to generate approximately 32.50 wetland credits through a combination of re-establishment, rehabilitation, and enhancement across multiple credit areas.
