Historical & Ecological Origin

Angostura Dam was constructed by the U.S. Bureau of Reclamation between 1949 and 1950 as part of the Angostura Unit of the Pick-Sloan Missouri Basin Program. Its primary purpose was irrigation and flood control for the Angostura Irrigation District. The reservoir was created by impounding the Cheyenne River. The surrounding land is part of the Great Plains physiographic province.

Facts & Legends

The name "Angostura" is Spanish for "narrow passage," referring to the narrow canyon where the dam was built. Local lore suggests that during periods of extreme drought, the reservoir's receding waters have revealed remnants of old homesteads, sparking tales of lost settlements.
