Lucky Peak Dam, located in Boise, Idaho, serves multiple purposes, including flood risk reduction, hydroelectric power generation, irrigation, and recreation. Completed in 1955 by the US Army Corps of Engineers, the dam stands at a structural height of 340 feet and has a storage capacity of over 300,000 acre-feet. While the dam greatly reduces flood risks downstream, there is still a potential for localized flooding during peak periods, necessitating careful management of water releases.

Despite its strong track record, Lucky Peak Dam is classified as having a "HIGH" hazard potential due to the possibility of catastrophic failure and the potential risks to surrounding communities. USACE conducts regular risk assessments and maintains close coordination with weather and emergency management agencies to optimize dam operations and respond promptly to any potential threats. The agency also monitors the dam during high water events and following earthquakes to address any performance issues that may arise, ensuring the safety and reliability of Lucky Peak Dam for the future.
