About this river

Allegheny River

The Allegheny River spans over 325 miles and originates in Potter County, Pennsylvania. It flows through the Allegheny Mountains and ultimately joins the Monongahela River to form the Ohio River. Native American tribes such as the Seneca, Shawnee, and Mohawk once inhabited the region before European settlers arrived in the 1700s. The river's hydrology and course have been altered by various dams, including the Kinzua Dam, which created the Allegheny Reservoir. The Conemaugh River Lake and Tionesta Lake are other major reservoirs along the river. The Allegheny River is used for a variety of recreational activities, such as fishing, boating, and camping. The river is also a source of drinking water for multiple towns and cities, and its watersheds support agricultural industries throughout the region.
