Completed in 1977, the dam serves multiple purposes including flood risk reduction, recreation, and water supply. Standing at a height of 160 feet with a hydraulic height of 145 feet, Dequeen Dam has a storage capacity of 370,600 acre-feet and a surface area of 1,700 acres.
Managed by the US Army Corps of Engineers, Dequeen Dam is equipped with an uncontrolled spillway and slide gates for water release. The dam poses a high hazard potential and undergoes regular inspections and emergency action plan updates to ensure public safety. USACE actively manages flood risks associated with the dam by monitoring its condition, prioritizing risk mitigation activities, and collaborating with local emergency managers to prepare for potential emergencies.
Despite the inherent risks associated with dam operations, USACE's comprehensive risk management measures aim to minimize the likelihood of dam-related emergencies and ensure the structural integrity of Dequeen Dam. By engaging with the community, implementing maintenance and repair strategies, and regularly updating emergency action plans, Dequeen Dam stands as a critical infrastructure for water resource management and climate resilience in the region.
