| | Bonneville Lock and Dam | | The U.S. Army Corps of Engineers operates and maintains Bonneville Lock and Dam for hydropower production, fish and wildlife protection, recreation and navigation. Since 1938, Bonneville Dam has supplied the region with inexpensive electrical power. Visitors can experience first-hand the operation of two hydroelectric powerhouses and watch migrating fish traveling upstream at the underwater viewing rooms next to the fish ladders. |

Many recreation opportunities are available along the shores of Lake Umatilla and on the John Day River, such as boating, fishing, swimming and sail boarding. This area is along the Lewis and Clark route. Day use facilities are only available. |
