Built in 1884, this dam serves multiple purposes including flood risk reduction, navigation, and water supply, with its primary function being recreation. Managed by the US Army Corps of Engineers, the dam has a storage capacity of 120,000 acre-feet and covers a surface area of 13,000 acres.
With a structural height of 15 feet and a hydraulic height of 15 feet, Pokegama Dam is a crucial infrastructure that plays a key role in managing water levels upstream and downstream while maintaining its structural integrity. Despite its significant hazard potential, the USACE implements various risk management measures to ensure the safety and stability of the dam. This includes regular inspections, emergency action plans, and collaboration with local emergency managers to raise awareness and readiness for potential dam-related emergencies.
In the face of increasing climate variability and the risk of severe weather events, the management of Pokegama Dam remains essential in mitigating flood risks and ensuring the safety of surrounding communities. With ongoing maintenance and monitoring, the US Army Corps of Engineers continues to uphold the dam's functionality and readiness to respond to any potential challenges that may arise in the future.
