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.
Angostura Recreation Area is located 10 miles southeast of Hot Springs off US Hwy. 385/18.
Angostura Recreation Area hosts an array of interpretive and educational activities during the summer season.
Nature Day Camps are offered once a month for kids ages 7-12. These hands-on activities enhance learning opportunities for younger park visitors that have an interest in the outdoors.
The reservoir has 36 miles of shoreline and some of the finest sandy beaches in the state. The lake’s average summer temperature is 66 degrees F. No lifeguard is on duty and swimming is at your own risk.
