By the 1790s, the Cornplanter Tract near the New York border in Warren County was the only self-governing Indian community remaining within the state of Pennsylvania. There a small Seneca community remained until 1959, when construction of the Kinzua Dam on the Allegheny River forced them to move. Most resettled on other Seneca lands in western New York.
