This project will widen and lower the elevation of a channel-wide sill on the Green River in Wyoming. The sill was constructed to support water diversion to the Killdeer Wetlands and now creates safety concerns for those recreating on the river and impedes. This project will improve fish passage and safety at the site while continuing to support the wetland area. Species that benefit from this work include native mountain whitefish, flannelmouth sucker, Kokanee and brown trout. Improving the current will providing habitat for migratory, wetland, raptor, and passerine birds, such as the trumpeter swan. Impacts from are expected to result in reduced annual rain and vital snowpack that feeds the Green River, while increasing extreme storm events. This project will allow necessary waterflow for fish passage in dryer future conditions while mediating against flood hazards. Completion of the project will increase outdoor recreation opportunities to support the community’s economic development.

The National Fish Passage Program: Leaders in Building Bridges and Fostering Connections
The National Fish Passage Program is a national leader connecting watersheds and people. The program has decades of experience implementing infrastructure projects with partners. Fish passage project proposals can be initiated by any individual, organization, government, or agency. However, proposals must be submitted and completed in cooperation with a Fish and Wildlife Conservation Office. (Please note that fish passage projects being used for federal or state compensatory mitigation or required by existing federal or state regulatory programs are not eligible for funding through the National Fish Passage Program.)
200 Million Dollar Investment in Rivers, Wildlife, and Communities
Clean free-flowing waterways are vital to wildlife, people, and ecosystems. But across the country, millions of barriers fragment rivers, block fish migration, and put communities at higher risk to flooding. The, signed in November 2021, included $200 million for restoring fish and wildlife passage by removing in-stream barriers and providing technical assistance under the National Fish Passage Program.
