Allegheny River

The Allegheny River (historically, especially in New York state, also spelled Allegany River) is a principal tributary of the Ohio River, which it forms with the Monongahela River at the downtown Pittsburgh's Golden Triangle "point". The river is approximately 325 mi (523 km) long, in the U.S. states of New York and Pennsylvania. It drains a rural dissected plateau of 11,580 sq mi (29,992 km²) in the northern Allegheny Plateau, providing the northeasternmost drainage in the watershed of the Mississippi River. Its tributaries reach to within 8 mi (13 km) of the shore of Lake Erie in southwestern New York. The valley of the river has been one of the most productive areas of energy extraction in U.S. history, with extensive deposits of coal, petroleum, and natural gas.
