Things To Do


The Angostura Dam and Reservoir are located at the southeast edge of the Black Hills on the Cheyenne River in southwestern South Dakota near the Nebraska border. Recreation on this 4,706 acre reservoir is managed by the South Dakota Department of Game, Fish and Parks for the Bureau of Reclamation and includes campgrounds, boat ramps, a fishing pier, and a marina. Fish species include walleye, bass, northern pike, perch, bluegill, and crappie. Because the reservoir is located on the southeastern edge of the Black Hills and is the only large body of water in an isolated area of arid southwestern South Dakota, it is attractive to migrating waterbirds that follow the eastern edge of the Black Hills. The lake also provides habitat for migrant passerine species that travel along the Cheyenne River on their twice-yearly flights to and from the north and the west. The best birding area is along the undeveloped western side.
