- The Bonneville Dam spans the width of the Columbia River. The Columbia River runs along the boundary between Oregon and Washington, so one side of the Bonneville Dam is in Multnomah County, Oregon, while the other side is in Skamania County, Washington.
- The Bonneville Dam is hydroelectric, which means that running water is converted into energy. Since 1938, the Bonneville Dam has provided inexpensive electrical energy to the region.
- The U.S. Army Corps of Engineers operates and maintains the Bonneville Dam year round.
- The Bonneville Dam has several fish ladders, a large visitor center, and several viewing windows where salmon and steelhead trout runs can be seen.
