The Green River Basin Fish and Wildlife Conservation Office plays a vital role in the recovery of endangered fish in the Colorado River Basin.

About Us

Our office supports a broad coalition of states, agencies, and private interest groups committed to establishing self-sustaining populations of endangered Colorado pikeminnow, razorback sucker, humpback chub, and bonytail while providing for new water development in the basin.

What We Do

The Green River Basin Fish and Wildlife Conservation Office plays a vital role in the recovery of endangered fish in the Colorado River Basin. Biologists at this field station, together with the Grand Junction Fish and Wildlife Conservation Office, conduct research, monitoring, and management activities on native fish populations and habitat with a goal of recovering bonytail, Colorado pikeminnow, humpback chub and razorback sucker. The station also works closely with the Ouray National Fish Hatchery to augment these endangered fish populations, utilizing state-of-the art facilities and techniques.

Our office assesses impacts of water development projects on endemic fish species of the Upper Colorado River system including the Green, White, and Yampa rivers. Species of interest include the Colorado pikeminnow and the razorback sucker where PIT tag antennas and river surveys are utilized for population monitoring.

Our Organization

The Fish and Aquatic Conservation program leads aquatic conservation efforts for the U.S. Fish and Wildlife Service. We are committed to tackling the nation’s highest priority aquatic conservation and recreational challenges to conserve, restore, and enhance fisheries for future generations.
