A towboat pushes barges of coal at the confluence of Pittsburgh from the Ohio River to the Monongahela, Feb. 11, 2023. The Army Corps of Engineers Pittsburgh District operates 23 locks and dams on the three main rivers of the greater Pittsburgh region, which supports inland navigation not just regionally but also nationally. The term "headwaters" refers to the sources and upper waters of a stream, and the Pittsburgh District is responsible for a region including the Allegheny, Monongahela, and Beaver rivers and their tributaries to their sources and the Upper Ohio River, which is formed by the confluence of its headwater streams at Pittsburgh. Historically, Pittsburgh is where American frontier engineers staged their campaigns during the Revolution to secure the Ohio and Mississippi basins for the United States. It is here that Army Engineers began their exploration for the American West, and here where pioneers boarded their frail craft to begin their voyages to new homes on the frontiers.
