Celilo Falls was dammed in 1957. The construction of dams on the Columbia River has consequently displaced many Native American communities and destroyed important natural habitats for minerals, flora and fauna. This is Oregon’s most controversial dam event, symbolizing the economic and political marginalization of Native Americans during our century. Celilo was a convention point where the eastern desert and the western forest met, where animals, plants, and people interchanged. Wyam (Celilo Falls) was the most important fishery and point of contact between Indians of all directions (Yakima, Umatilla, Nez Perce, Chinook and Warm Springs) from as far as Alaska, Idaho, California and all of Oregon.
On March 10, 1957, the community of Celilo and the Northwest looked on as a rising Lake Celilo rapidly silenced the waterfalls, submerged fishing platforms, rock formations and consumed their village, ending one of the oldest continuously inhabited communities on the North American continent (11,000 years old)
