Program Description and Priorities

The Jackson Hole One Fly Board (One Fly) funds projects benefiting the future of trout and fly fishing with emphasis on stream improvement and cutthroat trout conservation projects (protection, restoration, and enhancement) as well as applied stewardship education. We are requesting proposals from eligible governmental, Tribal or non-governmental organizations. All proposed projects must advance the One Fly mission of conservation and stewardship of trout and their habitats and must meet the specific criteria outlined below. Preference will be given to projects in the tributaries and main stem Snake and South Fork Rivers/Yellowstone basins of Idaho, Wyoming and Montana, and, especially those that benefit the Snake River Fine-Spotted cutthroat trout and the Yellowstone cutthroat trout. The Stream Habitat Improvements Program of the One Fly focuses on providing support for projects that protect, enhance and/or restore flows/ and in stream habitat for cutthroat trout species; however, applied research and education projects may be considered, as well as river access projects on a case by case basis if it can be demonstrated how results will lead to a specific measurable conservation outcome within a 3 year period. Proposals will be reviewed and evaluated by the Stream Habitat Improvements Committee comprised of One Fly volunteer representatives and scientific advisors. Final funding decisions are made by the Stream Habitat Improvement Committee and the One Fly Board of Directors.
