The Dalles Dam spans the Columbia River about two miles east of the town and links Wasco County, Oregon to Klickitat County, Washington. The dam was built between 1952 and 1957 by the US Army Corps of Engineers. It generates hydroelectricity and is managed by the Corps. The reservoir has been named Lake Celilo and stretches back 24 miles. Celilo was the name of the Native American trading and fishing village that was submerged, along with several waterfalls, when the dam flooded. Forty panels of rock carvings were removed and installed in the Columbia Hills State Park on the Washington side of the river.
