Flaming Gorge Dam
Flaming Gorge Dam is a concrete thin-arch dam on the Green River, a major tributary of the Colorado River, in northern Utah in the United States. Flaming Gorge Dam forms the Flaming Gorge Reservoir, which extends into southern Wyoming, submerging four distinct gorges of the Green River. The dam is a major component of the Colorado River Storage Project, which stores and distributes upper Colorado River Basin water. The dam takes its name from a nearby section of the Green River canyon, named by John Wesley Powell in 1869. It was built by the U.S. Bureau of Reclamation between 1958 and 1964. The dam is high and long, and its reservoir has a capacity of more than , or about twice the annual flow of the upper Green. Operated to provide long-term storage for downstream water-rights commitments, the dam is also a major source of hydroelectricity and is the main flood-control facility for the Green River system. The dam and reservoir have fragmented the upper Green River, blocking fish migration and significantly impacting many native species. Water released from the dam is generally cold and clear, as compared to the river's naturally warm and silty flow, further changing the local
