The Charleroi Locks and Dam, located on the Monongahela River in Pennsylvania, is a vital piece of infrastructure managed by the US Army Corps of Engineers. Completed in 1967, the dam serves primarily for navigation purposes, with a length of 701 feet and two locks each measuring 720 feet in length. It has a significant hazard potential due to the risk of erosion of the downstream riverbed, which could destabilize the stilling basin and potentially lead to the loss of the upper pool, impacting shipping temporarily.

To mitigate these risks, extensive rehabilitation work is underway at the Charleroi Locks and Dam, including the construction of an extension of the stilling basin and lock reconstruction. This project is expected to be completed by 2024 and aims to eliminate the primary vulnerability of the dam. The US Army Corps of Engineers works closely with stakeholders such as the Coast Guard and the shipping industry to communicate risks, conduct emergency exercises, and update emergency action plans regularly. They also monitor the stability of the structures through inspections and instrumentation, as well as provide public advisories on river levels and forecasts to ensure safety and awareness.
