About Bonneville Lock & Dam Visitors Center
The U.S. Army Corps of Engineers constructed and maintains the Bonneville Lock & Dam, which was the first federal lock and dam on the Columbia and Snake rivers. In 1938, the project’s initial powerhouse, spillway, and navigation lock were finished to enhance Columbia River navigation and supply hydropower to the Pacific Northwest. Both a larger navigation lock and a second powerhouse were finished in 1993.
The project is now an essential component of the system for managing water resources, which also provides habitat for fish and animals, power generation, improved water quality, irrigation, and enjoyment along the Columbia River.
A part of the Bonneville Lock and Dam Project, a Public Works Administration undertaking of President Franklin D. Roosevelt’s New Deal, was designated a National Historic Landmark in 1987.
National Historic Site
The significance of Bonneville is based on the Colonial Revival architecture of the administration building and auditorium, the innovative engineering design, the contribution to the industrial growth of the area, the function of the lock in transportation, the entrance landscaping, and the role of Bonneville as a significant government project in the 1930s to help with the Great Depression by creating jobs.
Army Captain Benjamin Bonneville, an early visionary who led an adventure to the Oregon Country and meticulously plotted large portions of what would become the Oregon Trail, is the subject of the name Bonneville Lock and Dam.
