Land area
Reservation of the Sioux (Wahpeton and Sisseton Bands) in North Dakota (area 497)
- 1867
Set aside as a reservation
In the record
Set apart at Devil's Lake for the Sisseton and Wahpeton Sioux by the 1867 treaty; a reservation, not a cession. The area covers about 226 thousand acres in what is now North Dakota.
The 1899 record names Sioux (as named in treaty records), Sisseton and Wahpeton as the people of this land.
This area was not ceded. The 1899 record shows it as a reservation the nation kept, at least until the record ends in 1894.
Today, Cheyenne River Sioux Tribe, Crow Creek Sioux Tribe, Flandreau Santee Sioux Tribe of South Dakota, Assiniboine and Sioux Tribes of the Fort Peck Indian Reservation, Montana, Lower Brule Sioux Tribe, Lower Sioux Indian Community in the State of Minnesota and 10 more carry the history of the people named here.

Shapes come from C. C. Royce’s 1899 maps as georeferenced by the US Forest Service. They are approximate and are not legal descriptions of land. Royce recorded land the United States treated as ceded; the shape does not show a nation’s territory.
