25 years of protecting the rivers you love

Idaho Rivers United is a conservation organization representing all who love the freedom, adventure and solitude of Idaho's rivers. Our mission is to protect and restore the rivers of Idaho.

Since our founding in 1990, IRU has become a powerful force for safeguarding Idaho's imperiled wild steelhead and salmon, protecting and enhancing stream flows and riparian areas, and defending and promoting the wild and scenic qualities of our wild rivers. Our supporters are river lovers who work together to keep Idaho's rivers healthy and flourishing for generations to come.
