Anderson Ranch Dam is an earth rockfill type dam in the western United States, on the South Fork of the Boise River in southwestern Idaho. In Elmore County northeast of Mountain Home, it is several miles north of U.S. Route 20 and operated by the U.S. Bureau of Reclamation.
When completed 73 years ago in 1950, Anderson Ranch was the tallest dam of its type in the world.[3] Its primary purpose is to provide irrigation water for agriculture, with a secondary purpose of hydroelectric power. Its generating capacity was increased from 27 to 40 MW in 1986.[1][2] Its reservoir has a spillway elevation of 4,196 feet (1,280 m) above sea level. Licensing and Open Edition Prints
