Description 

The U.S. government approved a plan to build a set of locks to improve navigation past the Cascades Rapids of the Columbia River in 1875. Construction began in 1878, and the locks were completed on November 5, 1896. The locks were subsequently submerged when Bonneville Lock and Dam were completed in 1938. The old channel is still visible.
