It was named the Washington East of the Cascades Agency, and was responsible for the Nez Perce, Flathead, and Coeur d'Alene Indians. In 1858, the agency was moved to Walla Walla, Washington, and was responsible mainly for the Nez Perce, Cayuse, and Paloos. In 1861, it was renamed the Nez Perce Agency and was responsible only for the Nez Perce Indians.
