Cascade Locks is a city in Hood River County, Oregon, United States. The city took its name from a set of locks built to improve navigation past the Cascades Rapids of the Columbia River. The U.S. federal government approved the plan for the locks in 1875, construction began in 1878, and the locks were completed on November 5, 1896. The locks were subsequently submerged in 1938, replaced by Bonneville Lock and Dam, although the city lost no land from the expansion of Lake Bonneville behind the dam some 4 miles (6 km) downstream of the city. The city population was 1,144 at the 2010 census.
Cascade Locks is in the northwest corner of Hood River County, on the south side of the Columbia River. It is bordered to the north (in the middle of the river) by Skamania County, Washington. The city of Stevenson, Washington, is north of Cascade Locks, across the river.
