1964–1965
Kinzua Dam displaces Seneca residents from treaty-protected land
Allegany Territory, New York; Kinzua Dam, Pennsylvania; Seneca Nation
The Kinzua Dam project forced Seneca residents from treaty-protected land and flooded nearly 10,000 acres of ancestral territory. Seneca remembrance places the removal in 1964; the Army Corps dates dam completion to 1965. On August 31, 1964, Congress enacted compensation provisions and authorized $12,128,917 for community rehabilitation, including relocation. The same law required a plan to withdraw federal supervision over the Seneca Nation, tying assistance to a threat to its federal relationship.

Context / qualification
The date range distinguishes removal from dam completion; it does not date every household’s move. Section 7 set January 1, 1965 as the latest date to vacate unless the Army permitted otherwise. The rehabilitation authorization was separate from property compensation and is not proof of full payment or adequate repair. Section 18 required a withdrawal plan; it did not itself terminate the federal relationship.
