Bonneville Lock and Dam were completed in 1937 to produce hydroelectric power and to ease navigation through the Columbia River Gorge. The dam comprises several structures, including two powerhouses, which combine to connect the Columbia’s Oregon and Washington shores. Oregon’s oldest fish hatchery also resides here. Named after Army officer Benjamin Bonneville, the dam today is a popular tourist attraction, with a stunning view of the scenic Gorge and viewing windows to observe fish migrating up the ladders.
