Elizabeth Locks & Dam

Elizabeth Locks & Dam is one of nine navigational structures on the Monongahela River between Pittsburgh, Pennsylvania and Fairmont, West Virginia. Maintained and built by the U.S. Army Corps of Engineers, the gated dam forms an upstream pool that extends for 23.8 miles, stretching to Charleroi, Pennsylvania.

The dam is located at mile 23.8 of the Monongahela River; it was modernized during a major reconstruction project in 1979–80. The dam is scheduled for removal in July 2024.
