Crow Creek Indian Reservation

The Crow Creek Indian Reservation (Dakota: Khąǧí wakpá okášpe, Lakota: Kȟaŋğí Wakpá Oyáŋke), home to Crow Creek Sioux Tribe (Dakota: Khąǧí wakpá oyáte) is located in parts of Buffalo, Hughes, and Hyde counties on the east bank of the Missouri River in central South Dakota in the United States. It has a land area of 421.658 square miles (1,092.09 km2) and a 2000 census population of 2,225 persons. The major town and capital of the federally recognized Crow Creek Sioux Tribe is Fort Thompson. The town is located adjacent to the Big Bend Dam, which holds back Big Bend Reservoir (also known as Lake Sharpe), one of the four Missouri Mainstem reservoirs constructed by the US Army Corps of Engineers in the Pick-Sloan Plan. Authorized in 1944 for flood control and hydropower, the dam and lake were completed in the 1960s.
