Angostura State Recreation Area is one of the few large reservoirs in western South Dakota. The lake’s crystal waters and strong fishery make it a a water enthusiast’s haven for fishing, swimming, boating or a day on the beach.
The dam was built in 1949 by the Bureau of Reclamation across the Cheyenne River for irrigation purposes, but it paved the way for a recreation area. The word “angostura” is Spanish for narrows.
