Maxwell Lock & Dam
Maxwell Lock and Dam is a navigational lock and gated dam on the Monongahela River between Centerville in Washington County, and Luzerne Township in Fayette County in Pennsylvania. It is part of a series of dams that canalizes the Monongahela to a depth of at least for its entire length from Fairmont, West Virginia to Pittsburgh, Pennsylvania. It is maintained by the U.S. Army Corps of Engineers, Pittsburgh District.
Maxwell has two lock chambers located on the right-descending river bank. The dam's upper pool extends about upstream to Grays Landing Lock and Dam at Grays Landing, Pennsylvania.
