Prior to the 1855 Treaty, the Tribes’ economy consisted primarily of intertribal trade, livestock, trade with fur companies, hunting, fishing and gathering. Today, the economy includes agriculture, livestock, tourism, a travel plaza, grain elevator, the Wildhorse Resort (casino, hotel, RV Park, golf course), Tamástslikt Cultural Institute, Cayuse Technologies, and Coyote Business Park, a 520 acre commercial and light industrial business development on Interstate 84. The reservation is also home to the Umatilla National Forest Supervisor’s Office.

History and culture
Three tribes make up the CTUIR: Cayuse, Umatilla, and Walla Walla. They have lived on the Columbia River Plateau for over 10,000 years, an area of about 6.4 million acres in what is now northeastern Oregon and southeastern Washington. In 1855, the tribes and the United States Government negotiated a treaty in which the tribes ceded 6.4 million acres of land in exchange for reservation land. The CTUIR reserved rights in the treaty, including fishing and hunting rights and the right to gather traditional foods and medicines on public lands within the ceded areas.
The traditional religion of the tribes is called “Washat” or “Seven Drums.” Native languages are still spoken by some and a language preservation program is helping to re-establish the languages.
