Шаблон:Distinguish Шаблон:Infobox dam Angostura Dam is an embankment dam across the Cheyenne River in Fall River County in southwestern South Dakota in the United States, about Шаблон:Convert south of Rapid City. The dam consists of an earth-fill embankment with a concrete spillway section, Шаблон:Convert high and Шаблон:Convert long; it withholds the Шаблон:Convert Angostura Reservoir.[1][2] The dam was conceived as early as 1913, but it was not until the 1930s when a regional drought caused crop failures that the project received widespread support from farmers.[3] Built from 1946 to 1949, the dam is part of the Angostura Division of the Pick-Sloan Missouri Basin Program, and is operated by the U.S. Bureau of Reclamation.[4]
The dam's primary purpose is to store water for the irrigation of Шаблон:Convert of project lands. The service area lies along Шаблон:Convert of the Cheyenne River below the dam, and is supplied by the Angostura Canal, which has a diversion capacity of Шаблон:Convert.[4] The dam and reservoir regulate runoff from an area of Шаблон:Convert.[2] The reservoir has a conservation storage capacity of Шаблон:Convert, with an extra Шаблон:Convert of surcharge, flood-control storage. Flood water releases are controlled by a spillway with five radial gates, which can pass up to Шаблон:Convert.[2][4]
Angostura Reservoir is one of the only large lakes in western South Dakota. With Шаблон:Convert of shoreline and Шаблон:Convert of water,[5] the reservoir is stocked with several species of fish, including walleye, smallmouth bass and crappie.[6]
The Angostura Recreation Area operated by the South Dakota Department of Game, Fish, and Parks surrounds the lake.
