Upper Colorado River Endangered Fish Recovery Program

In 1988, the Upper Colorado River Endangered Fish Recovery Program was established to help bring four species of endangered fish back from the brink of extinction: the humpback chub, bonytail, Colorado pikeminnow, and razorback sucker.

The Recovery Program is a unique partnership of local, state, and federal agencies, water and power interests, and environmental groups working to recover endangered fish in the Upper Colorado River Basin while water development proceeds in accordance with federal and state laws and interstate compacts.

With its demonstrated successes, the Upper Colorado River Endangered Fish Recovery Program has become a national model for its collaborative conservation efforts to protect endangered species.
