Beaver River (Pennsylvania)
The Beaver River is a tributary of the Ohio River, approximately 21 mi (34 km) long, in western Pennsylvania in the United States.
It is formed in Lawrence County, approximately 3 mi (5 km) southwest of New Castle, by the confluence of the Mahoning and Shenango rivers. It flows generally south, past West Pittsburgh and Homewood, roughly parallel to the border with Ohio. It receieves Connoquenessing Creek west of Ellwood City, and flows south past Beaver Falls and New Brighton. It joins the Ohio at Rochester, near a sharp bend in the Ohio, approximately 20 mi (32 km) northwest (and downstream from) Pittsburgh.
In the lower reaches near the Ohio the river cuts through a gorge of underlying sandstone. The surrounding area is historically important coal-producing region.
