The Dalles Dam

The Dalles Lock and Dam is a concrete-gravity run-of-the-river dam spanning the Columbia River, two miles (3.2 km) east of the city of The Dalles, Oregon, United States. It joins Wasco County, Oregon, with Klickitat County, Washington, 192 miles (309 km) upriver from the mouth of the Columbia near Astoria, Oregon. The closest towns on the Washington side are Dallesport and Wishram. The U.S. Army Corps of Engineers (USACE) began work on the dam in 1952 and completed it five years later. Slack water created by the dam submerged Celilo Falls, the economic and cultural hub of Native Americans in the region and the oldest continuously inhabited settlement in North America. Inhabitants of the submerged area include the Wasco–Wishram and Skinpah. On March 10, 1957, hundreds of observers looked on as the rising waters rapidly silenced the falls, submerged fishing platforms, and consumed the village of Celilo. Ancient petroglyphs were also in the area being submerged. Approximately 40 petroglyph panels were removed with jackhammers before inundation and were placed in storage before being installed in Columbia Hills State Park in the 2000s. The reservoir behind the dam is named Lake Celilo and runs 24 miles (39 km) up the river channel, to the foot of John Day Dam. The dam is operated by the USACE, and the power is marketed by the Bonneville Power Administration (BPA). It is part of an
