Thompson Wetland and Stream Mitigation Bank

The Thompson Wetland and Stream Mitigation Bank is an approximately 56.2- acre restoration site located in Flathead County, Montana in the scenic Thompson River Valley. The Bank restores over 5,000 linear feet of riparian habitat re-establishes and enhances 20.94 acres of wetlands, and preserves 24.2 acres of upland habitat along the Thompson River. When complete, the project will improve water quality, increase floodplain connectivity, and support species biodiversity.

WES will excavate and grade the existing stream banks, which have been eroded and manipulated over time. Our team will remove earthen berms on the site, reconnecting the river to the floodplain. In addition, WES will reduce invasive species on the site, supporting native wetland vegetation, including grasses, sedges, and rushes. These efforts will improve water quality and create structurally diverse habitats that support native wetland and riparian plant communities.
