Allegheny River

ALLEGHENY RIVER. The Allegheny River rises in Potter County, Pennsylvania, and flows in an arc through New York then back into Pennsylvania for a total length of about 325 miles. It unites with the Monongahela River to form the Ohio River, and the early French and English explorers considered the Allegheny a part of the Ohio. The Delawares and Shawnees settled along the Allegheny's course soon after 1720. After 1790 the river became an important highway for American settlers and freight in the keelboat and flatboat era.
