Allegheny River
Summary
The Allegheny River (ˌælɪˈɡeɪni ) is a headwater stream of the Ohio River that is located in western Pennsylvania and New York in the United States. It runs from its headwaters just below the middle of Pennsylvania's northern border, northwesterly into New York, then in a zigzag southwesterly across the border and through Western Pennsylvania to join the Monongahela River at the Forks of the Ohio at Point State Park in Downtown Pittsburgh, Pennsylvania.
The Allegheny River is, by volume, the main headstream of both the Ohio and Mississippi Rivers. Historically, the Allegheny was considered to be the upper Ohio River by both Native Americans and European settlers.
This shallow river has been made navigable upstream from Pittsburgh to East Brady by a series of locks and dams that were constructed during the early 20th century. A 24-mile-long portion of the upper river in Warren and McKean counties of Pennsylvania and Cattaraugus County in New York forms the Allegheny Reservoir, which was created by the erection of the Kinzua Dam in 1965 for flood control.
The name of the river is derived from one of a number of Delaware/Unami phrases that are homophones of the English name, with varying translations.

The name Allegheny probably comes from Lenape welhik hane or oolikhanna, which means 'best flowing river of the hills' or 'beautiful stream'. There is a Lenape legend of a tribe called "Talligewi" who used to live along the river. Frederick Webb Hodge cited Henry Schoolcraft to connect the "Talligewi" to the Cherokee.
The following account of the origin of the name Allegheny was given in 1780 by Moravian missionary David Zeisberger: "All this land and region, stretching as far as the creeks and waters that flow into the Alleghene the Delawares called Alligewinenk, which means 'a land into which they came from distant parts'. The river itself, however, is called Alligewi Sipo. The whites have made Alleghene out of this, the Six Nations calling the river the Ohio.
