Throughout this period, native people continued to fish at Celilo, under the provisions of the 1855 Treaties signed with the Yakama Nation, the Confederated Tribes of Warm Springs, and the Walla Walla, Umatilla, and Cayuse, which guaranteed the tribes' ancient "right of taking fish at all usual and accustomed stations." In 1947, the federal government convened Congressional hearings and concluded that the proposed dam at The Dalles would not violate tribal fishing rights under the treaties. Subsequently, the government reached a monetary settlement with the affected tribes, paying $26.8 million for the loss of Celilo and other fishing sites on the Columbia.
