|Today, over 9,365 descendants of 12 aboriginal tribes of Indians are enrolled in the Confederated Tribes of the Colville Reservation. The tribes, commonly known by English and French names, are: the Colville, the Nespelem, the San Poil, the Lake, the Palus, the Wenatchi (Wenatchee), the Chelan, the Entiat, the Methow, the southern Okanogan, the Moses Columbia and the Nez Perce of Chief Joseph’s Bands.
The Colville Indian Reservation was established by Presidential Executive Order in 1872 and was originally twice as large as it is today.
The Colville Indian Reservation land base covers 1.4 million acres or 2,100 square acres located in North Central Washington, primarily in Okanogan and Ferry counties.
The Colville Indian Reservation is occupied by over 5,000 residents, both Colville tribal members and their families and other non-Colville members, living either in small communities or in rural settings. Approximately fifty percent of the Confederated Colville Tribes' membership live on or adjacent to the reservation.--from The Confederated Tribes of the Colville Reservation Fact Sheet
