This Final Environmental Assessment (EA) discusses alternatives for providing endangered fish passage at the Price-Stubb Diversion Dam on the Colorado River in Mesa County, Colorado. It was prepare by the U.S. Bureau of Reclamation in cooperation with the U.S. Fish and Wildlife Service to comply with the National Environmental Policy Act, Endangered Species Act, and related U.S. Department of the Interior policies and regulations.

Construction of the eight-foot high Price-Stubb Diversion Dam, owned by Palisade Irrigation District and Mesa County Irrigation District, was completed in 1911 to divert irrigation water. In 1919, the dam was no longer used following completion of Reclamation's Grand Valley Project Diversion Dam and the Government Highline Canal.

Since 1987, federal and state agencies, water users, and environmental interests have been cooperating in the Upper Colorado River Endangered Fish Recovery Program (Recovery Program). The goal of the Recovery Program is to establish self-sustaining populations of the four endangered fish species in the Upper Colorado River Basin while allowing for continued use and future development of Colorado River water supplies. The Recovery Program has developed a basin-wide action plan that includes restoring fish passage. Action is necessary to restore fish passage at the Price-Stubb Diversion Dam to meet the agreed upon schedule of the basin-wide Recovery Program and to make sufficient progress toward recovering the endangered fish.
