Army Corps of Engineers to reduce flood risk for downstream communities along the North Branch Potomac River. Completed in 1981, this rockfill dam stands at a height of 296 feet and has a storage capacity of 130,900 acre-feet. While the dam plays a vital role in mitigating flooding, there are still potential risks associated with high-volume water releases from the spillway during significant storm events.
In the event of a breach, communities such as Bloomington, Luke, Westernport, and Cumberland could face devastating flooding, with swift and deep floodwaters causing extensive damage to properties and infrastructure. To manage these risks, the USACE implements regular inspections, maintenance activities, and emergency response exercises to ensure the dam's integrity and readiness for any potential flood event. Despite the risks, the USACE's proactive risk management measures and preparedness efforts help safeguard downstream communities and reduce the likelihood of catastrophic flooding incidents.
Overall, Jennings Randolph Dam serves as a critical flood risk reduction infrastructure, highlighting the importance of ongoing monitoring, maintenance, and emergency preparedness to protect communities along the North Branch Potomac River from the impacts of potential dam-related flooding events.
