The reservation covers 404 square miles in Lyman and Stanley counties in central South Dakota, bounded on the northeast and east by the Missouri River, which was closed by the Big Bend Dam in 1963. On the east and north side of the reservoir, Lake Sharpe, is the Crow Creek Reservation. The Lower Brule Reservation population is 1,664 and tribal membership is 3,410. The Agency headquarters is located in the Lower Brule Tribal Administration building, newly constructed in 2001, staffed with 15 permanent employees. The Lower Brule Sioux Tribe is the largest employer on the reservation, operating many BIA and IHS programs, the Golden Buffalo Casino & Motel, Tribal Farm, propane plant, popcorn processing plant, a construction company, and hunting enterprise.
