Warm Springs Indian Reservation
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. 
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.
The reservations's only significant population center is the community of Warm Springs (also known as the Warm Springs Agency), which comprises over 73 percent of the reservation's population.
The Warm Springs Reservation is one of the last holdouts in the U.S. of speakers of the Chinook Jargon because of its utility as an intertribal language. The forms of the Jargon used by elders in Warm Springs vary considerably from the heavily-creolized form at Grand Ronde.
As of 2003, the reservation was home to a tribal enrollment of over 4,200. The biggest source of revenue for the tribes is hydroelectric (Warm Springs Power Enterprises) projects on the Deschutes River. The tribes also operate Warm Springs Forest Products Industries.
Many tribal members engage in ceremonial, subsistence, and commercial fisheries in the Columbia River for salmon, steelhead, and sturgeon. Tribal members also fish for salmon and steelhead for subsistence purposes in the Deschutes River, primarily at Sherars Falls. Tribal members also harvest Pacific lamprey at Sherars Falls and Willamette Falls. The tribe's fishing rights are protected by treaty and re-affirmed by court cases such as Sohappy v. Smith and United States v. Oregon.
In 1964, the first part of the Kah-nee-ta resort was completed—Kah-nee-ta Village—a lodging complex with a motel, cottages and tipis. The resort would eventually include a lodge, casino, convention center and golf course. Due to lack of rentability, the resort was closed in September 2018. 
The Indian Head Casino on U.S. Route 26 opened in February 2012. It has 18,000 square feet (1,700 m2) of gaming space, with 500 slot machines and 8 blackjack tables. The tribes expect the casino to net $9 to 12 million annually. The casino previously operated at Kah-Nee-Ta, where it had only 300 slot machines and made $2 to 4 million a year. The new location was intended to be more accessible to travelers, since Kah-nee-ta is located about a half an hour from Highway 26.
Other business ventures
In 2016, the tribe's lumber mill, also located on Highway 26 near the village of Warm Springs, shut down. It had been operating for decades but output had declined in recent years. One solution proposed by a tribal entity, Warm Springs Ventures, to create new revenue and jobs for the tribe was the launch of three new business ventures: cannabis cultivation, extraction and distribution; drone training, certification and manufacture; and a carbon offset venture that would sell carbon offsets to major polluters. All three ventures were expected to be operating sometime in 2017. The tribe was awarded the right by the Federal Aviation Administration to certify drone operators in 2016. The cannabis project was approved by a vote of tribal members but as of October 2016 still faced administrative and funding challenges.
