Navigable to milepost 89.5, the Allegheny River is used primarily for recreation but is still travelled by commercial traffic as well. In 1992, it was given the designation of Wild & Scenic River and was voted River of the Year in 2017.

 Course of the Allegheny

Starting in the Allegheny highlands, the Allegheny River eventually joins the Monongahela to form the Ohio River in Downtown Pittsburgh. Along the way, it receives the waters of twenty-one major tributaries and dozens of smaller streams that collectively drain an area of close to 12,000 square miles.
