Angostura Reservoir

Southwest South Dakota, close to the Nebraska border, is home to the Angostura Reservoir, which is situated on the Cheyenne River at the southeast edge of the Black Hills. The reservoir contains 42 miles of shoreline, 4,407 acres of water surface, and 4,546 acres of land. Although Angostura Reservoir was initially constructed for irrigation, it is now a highly well-liked recreation area.

The SD Department of Game, Fish, and Parks oversees recreation on this reservoir for the Bureau of Reclamation and manages campgrounds, boat ramps, a fishing pier, and marinas. Walleye, bass, northern pike, perch, bluegill, and crappie are some of the fish species. The reservoir attracts migrating waterbirds that follow the eastern edge of the Black Hills because it is situated on the southeast side of the Black Hills and is the only significant body of water in a remote region of arid southwestern South Dakota. On their twice-yearly migrations to and from the north and west, migrant passerine species that move along the Cheyenne River can also find habitat in the lake. The undeveloped western side is the finest spot for bird watching. There is always an admission fee and the area is always open. Part of the Pick-Sloan Missouri Basin Program is the Angostura Unit.

The lake's 66-kilometer shoreline features some of the state's top beaches. The Bailey Recreation Area runs along the lake's southern end, while the Angostura Recreation Area occupies the whole eastern shoreline.
