Summary
Significance: Bonneville Dam was the first of eight federal lock and dam projects on the Columbia-Snake rivers. The dam's significance is derived from its unique engineering design, its contribution to the region's industrial development, the lock's role in transportation, the entrance landscaping and Colonial Revival style architecture of the administration and auditorium buildings, and the project's role as a major government undertaking in the 1930s to combat the Great Depression. Bonneville Dam was placed on the National Register of Historic Place as an historic district in 1986 and named a National Historic Landmark in 1987.
