History
The Grand River Agency was established in 1869, reporting to the Dakota Superintendency and associated with the Upper Platte Agency. After 1870, the agent reported directly to the Office of Indian Affairs in Washington, DC. The Grand River Agency was primarily responsible for the Upper and Lower Yanktonai, Hunkpapa, Cut Head (Pabaska), and Blackfeet Sioux. Other bands of the Sioux, including the Two Kettle (Oohenonpa), Sans Arcs, Oglala, and Brulé, also were associated with this agency. In July 1873, the agency was moved from the junction of the Grand and Missouri Rivers in South Dakota to its present location 50 miles up-stream on the Missouri River at Standing Rock, North Dakota. The name of the agency was officially changed to Standing Rock Agency in December 1874.
