Bonneville Locks and Dam, located on the Columbia River in Oregon, is a federal structure owned and operated by the US Army Corps of Engineers. Completed in 1938, this gravity dam serves primarily for navigation purposes, with hydroelectric power generation, recreation, and other functions also in play. The dam stands at a height of 197 feet and stretches 2,477 feet in length, with a spillway width of 1,450 feet. It features two locks, each 675 feet long and 85 feet wide, facilitating the passage of vessels along the river.

With a very high risk assessment due to the inherent hazards associated with dam operations, the US Army Corps of Engineers diligently manages flood risks at Bonneville Locks and Dam. This entails ongoing monitoring of the dam's condition, prioritizing risk-reducing activities, and engaging with local emergency managers and the public to ensure readiness for any potential emergencies. Regular maintenance and repairs are conducted to ensure the dam's structural integrity and functionality. These efforts underscore the importance of proactive risk management and preparedness in safeguarding the surrounding communities and the environment from potential dam-related emergencies.
