Flaming Gorge Dam 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
Welbedacht Dam dam wall. For various reasons, however, constructing a smaller scheme on the Caledon River was implemented before completion of the Vanderkloof Dam. The Welbedacht Dam on the Caledon River was constructed as the main storage element of the CMRGWS and water is abstracted from this dam for transfer to Bloemfontein and various smaller users along the way. The Welbedacht Dam is a concrete barrage-type dam on the Caledon River, which was designed and constructed by the Department of Water Affairs. The dam has a catchment area of some 15 245 km² with a natural mean annual runoff (MAR) around 1210
