Kinzua Dam, also known as Allegheny Reservoir, is a rockfill dam located in Warren, Pennsylvania, along the Allegheny River. Built in 1965 by the US Army Corps of Engineers, the primary purpose of the dam is flood risk reduction, with additional benefits including fish and wildlife pond, hydroelectric power generation, and recreation. The dam stands at a structural height of 177 feet and has a storage capacity of 1.3 million acre-feet.

Despite being well-constructed and maintained, Kinzua Dam poses a high hazard potential due to the large populations living downstream in communities like Warren, Oil City, Franklin, and metropolitan Pittsburgh. The risk assessment conducted in 2020 classified the dam's risk as high, with the most likely flooding scenarios involving high-volume releases through the spillway during intense storm events or a potential breach from extreme rainfall events. Emergency management measures are in place to monitor reservoir levels, conduct emergency exercises, and engage with local communities to enhance flood preparedness.

In the event of a dam breach or significant flood, downstream communities could face swift and deep floodwaters, potentially overflowing levees and causing significant property damage and loss of life. The US Army Corps of Engineers is committed to working closely with state and local emergency managers to mitigate risks, enhance monitoring and surveillance, and provide timely information to residents to ensure readiness for potential flood events.
