The Dalles Dam is a US Army Corp of Engineers project on the Columbia River between Washinton and Oregon. Building the dam angered many by violating Indian fishing rights when it flooded the spectacular Celilo falls area and forever buried much of the ancient history of the Columbia Basin in 1957. The Dalles Dam inundated Celilo Falls, Tenmile Rapids, Fivemile Rapids, and other nearby falls. For thousands of years Indians had fished these falls, building scaffolds out over the rushing water and plying the river with long-handled dipnets.
