the Kinzua Dam


The Kinzua Dam, on the Allegheny River in Warren County, Pennsylvania, is one of the largest dams in the United States east of the Mississippi River.

Pennsylvania, officially the Commonwealth of Pennsylvania, is a state located in the northeastern and Mid-Atlantic regions of the United States.

The Allegheny River is a principal tributary of the Ohio River; it is located in the Eastern United States.

The Mississippi River is the chief river of the largest drainage system on the North American continent.

The dam is located 6 miles east of Warren, Pennsylvania, along Route 59, within the 500,000-acre Allegheny National Forest.


A boat marina and beach are located within the dam boundaries.


In addition to providing flood control and power generation, the dam created Pennsylvania's second deepest lake, the Allegheny Reservoir, also known as Kinzua Lake.


Quaker Lake, a smaller artificial lake that empties into the reservoir, was also formed as a result of the dam.


The lake extends 25 miles to the north, nearly to Salamanca, New York, which is within the Allegany Reservation of the Seneca Nation of New York.

Salamanca is a city in Cattaraugus County, New York, United States, inside the Allegany Indian Reservation, one of two governed by the Seneca Nation of New York.

The Seneca Nation of Indians is a federally recognized Seneca tribe based in western New York.


Federal condemnation of tribal lands to be flooded for the project displaced more than 600 Seneca members and cost the reservation 10,000 acres, nearly one-third of its territory and much of its fertile farmland.
