Locks and Dams

From the days of wooden wicket dams to today's modern technology, improving and maintaining the navigability of our nation's waterways has been a priority for the U.S. Army Corps of Engineers. The Pittsburgh District operates 23 locks & dams on the Allegheny, Monongahela & Ohio Rivers.
