The Big Hole River Foundation is a science-based organization that works to protect the Big Hole River watershed through conservation programs, education outreach, research, and community building.

The Big Hole River valley encompasses 2,800-square miles of free-flowing, blue-ribbon trout streams, several mountain ranges, and many plant and animal species-of-concern, including the last remaining population of stream-dwelling Arctic grayling found in the Lower 48 United States.


While a picturesque Rocky Mountain river valley, the Big Hole is affected by pollution, warming temperatures, development, noxious weeds, wildfires, and socioeconomic change.

BHRF works with local, state, and federal agencies, sportsmen groups, businesses, landowners, nonprofits, and recreationists to support smart, strategically focused conservation and restoration efforts.

We have a lot of work to do and with YOUR help we can conserve this rare and beautiful resource for future generations. Please JOIN US!


We protect, conserve, and enhance the free-flowing Big Hole River and its unique culture, fisheries, and wildlife.
