Completed in 1949 by the US Army Corps of Engineers, the dam stands at 110 feet tall and spans 2990 feet in length. Its primary purpose is flood risk reduction, with a normal storage capacity of 365,200 acre-feet and a maximum discharge of 986,000 cubic feet per second.
Despite being classified as having a high hazard potential, the USACE has implemented various risk management measures to mitigate the potential impact of a dam failure on surrounding communities. These measures include conducting emergency exercises, updating the Emergency Action Plan, and maintaining the dam's integrity through regular inspections and maintenance activities. In the event of a dam failure, towns such as Fort Gibson, Muskogee, and Okay would be most immediately impacted, with widespread flooding resulting in loss of life and damage to infrastructure along the river.
Overall, Fort Gibson Dam plays a crucial role in protecting downstream communities from flooding events. Through diligent risk management practices and ongoing monitoring, the USACE is committed to ensuring the safety and integrity of the dam for both residents and the environment.
