Completed in 1884, the dam serves multiple purposes, including flood risk reduction, navigation, water supply, and recreation. With a height of 17 feet and a volume of 3,700 cubic feet, the dam has a significant hazard potential and a very high risk assessment rating.
Operated by the US Army Corps of Engineers, Pokegama Dam is regularly inspected and monitored to ensure its structural integrity and manage flood risks effectively. The dam has a controlled spillway with a width of 108 feet to regulate water levels and prevent overtopping during severe weather events. In case of emergencies, an Emergency Action Plan (EAP) is in place to guide response and evacuation procedures, meeting established guidelines and ensuring public safety.
USACE actively engages with local emergency managers and the public to raise awareness about the dam and promote preparedness for potential emergencies. By prioritizing maintenance and repairs, as well as updating the EAP regularly, efforts are made to mitigate flood risks and ensure the dam's functionality. Despite the inherent risks associated with dams, USACE continues to work towards addressing all types of flood risks and maintaining the safety and integrity of Pokegama Dam.
