Completed in 1952, the dam stands at a height of 197 feet and has a storage capacity of 1,230,800 acre-feet. Primarily designed for flood risk reduction, the dam also serves a secondary purpose of hydroelectric power generation. With a maximum discharge capacity of 290,400 cubic feet per second, the dam is equipped with a controlled spillway to manage floodwaters.
Despite being classified as having a high hazard potential, the US Army Corps of Engineers (USACE) has implemented various risk management measures to ensure the dam's integrity and minimize potential impacts in the event of a failure. This includes conducting emergency exercises, updating the Emergency Action Plan, and maintaining a detailed communication plan. Additionally, the dam undergoes routine inspections and has an instrumentation and monitoring program in place to monitor changing conditions.
In the event of a dam failure, the towns of Gore and Webbers Falls in Oklahoma, as well as Fort Smith and Van Buren in Arkansas, would be most immediately impacted. USACE's proactive approach to risk management and ongoing maintenance efforts demonstrate their commitment to safeguarding the community and ensuring the continued safe operation of Tenkiller Dam.
