The Warm Springs Indian Reservation consists of 1,019.385 square miles (2,640.20 km2) in north-central Oregon, in the United States, and is occupied and governed by the Confederated Tribes of Warm Springs.
Three tribes form the confederation: the Wasco, Tenino (Warm Springs) and Paiute. Since 1938 they have been unified as the Confederated Tribes of Warm Springs.
The reservation was created by treaty in 1855, which defined its boundaries as follows:
Commencing in the middle of the channel of the Deschutes River opposite the eastern termination of a range of high lands usually known as the Mutton Mountains; thence westerly to the summit of said range, along the divide to its connection with the Cascade Mountains; thence to the summit of said mountains; thence southerly to Mount Jefferson; thence down the main branch of Deschutes River; heading in this peak, to its junction with Deschutes River; and thence down the middle of the channel of said river to the place of beginning.
The Warm Springs and Wasco bands gave up ownership rights to a 10,000,000-acre (40,000 km2) area, which they had inhabited for over 10,000 years, in exchange for basic health care, education, and other forms of assistance as outlined by the Treaty with the Tribes of Middle Oregon (June 25, 1855). Other provisions of the Treaty of 1855 ensured that tribal members retained hunting and fishing rights in the "Natural and Accustomed Area" which they had vacated. These treaty hunting and fishing rights are rights that were retained by the tribe and are not "special rights" granted by the U.S. government. [1]
In 1879, the U.S. government moved a small group of Paiutes to the reservation in spite of that tribe's history of conflict with Columbia River tribes.
The reservation lies primarily in parts of Wasco County and Jefferson County, but there are smaller sections in six other counties; in descending order of land area they are: Clackamas, Marion, Gilliam, Sherman, Linn and Hood River counties. (The Hood River County portion consists of tiny sections of non-contiguous off-reservation trust land in the northeast corner of the county.) The reservation is 105 miles (169 km) southeast of Portland; 348,000 acres (1,410 km2), over half, is forested. Its 2000 census total population was 3,314 inhabitants.
