The principal surviving Sahaptin communities are on the Warm Springs Reservation in northern Oregon (about 50 speakers of Tenino); on the Umatilla Reservation in northeastern Oregon, near Pendleton (25 to 50 speakers of Umatilla and Walla Walla); and at Toppenish on the Yakima Reservation in south central Washington (about 25 fluent speakers and a larger number of less-fluent speakers of Yakima). There is also a small Wanapam-speaking community near Priest Rapids Dam on the Columbia River. A scattering of Sahaptin speakers can also be found among speakers of Okanagan and Nez Perce on the Colville Reservation in northeastern Washington.
