The Cheyenne River Sioux Reservation is part
of the Great Sioux Reservation that was established under the Treaty of
1868. This treaty established a reservation of 60,000,000+ acres that
encompassed all of western South Dakota, North Dakota, Eastern Wyoming,
and parts of Nebraska and Montana. The Sioux Agreement of March 02,
1889 set reservation boundary lines to encompass approximately
2,806,913.95 acres. The Surplus Lands Act of 1908 and 1910 authorized
the Secretary of Interiors to open 1.6 million acres of the Cheyenne
River Sioux Reservation for homesteading and settlement by non-Indians.
Land which the tribe has attempted to restore to tribal ownership to
this day.The eastern boundary of the Great Sioux Nation is the east bank
of the Missouri River and is also the boundary of the eastern edge of
the Cheyenne River Sioux Reservation. The construction of the Oahe
Reservoir in 1948- and 1962 supposedly removed 104,420 acres of trust
land from the reservation due the illegal building of the dam. But,
pursuant to Public Law 778, the reservations boundaries were not altered
by the United States taking of lands. |
