Ice Harbor Lock and Dam, also known as Lake Sacajawea, is a federal structure located on the Snake River in Pasco, Washington. Completed in 1962 by the US Army Corps of Engineers, this concrete dam serves primarily for navigation purposes, but also supports fish and wildlife ponds, hydroelectric power generation, and recreational activities. With a hydraulic height of 100 feet and a structural height of 208 feet, the dam spans 2,790 feet in length and has a storage capacity of 406,500 acre-feet.

Managed and operated by the US Army Corps of Engineers, Ice Harbor Lock and Dam poses a high hazard potential due to its limited water storage capacity and the risk of flooding in severe weather events. To address these risks, the Corps implements various risk management measures, including continual monitoring of the dam's condition, prioritizing activities to reduce risks, and engaging with local emergency managers and the public to raise awareness and preparedness for potential dam-related emergencies. Regular maintenance and repairs are also conducted to ensure the dam's structural integrity and functionality.

Despite the risks associated with dams, the US Army Corps of Engineers works diligently to manage flood risks and ensure the safety of Ice Harbor Lock and Dam. By maintaining a proactive approach to monitoring, risk assessment, and emergency preparedness, the Corps aims to mitigate potential hazards and protect downstream communities from the impacts of dam-related emergencies.
