For the next four years, the Seneca Nation and our Seneca people fought to prevent the dam from being built. Its construction would mean the taking and subsequent flooding of our Seneca communities in our Allegany Territory.
What Kind of Dam is it?Kinzua Dam is a combination concrete gravity structure and rolled-earth embankment dam. Between October 15, 1960 and September 29, 1961, the U.S. Army Corps of Engineers built the two rolled-earth embankments that sat on either side of the concrete gravity structure. The earth embankments alone were made up of over one-half million yards of earth.
The construction of Kinzua Dam in Warren, Pennsylvania was completed in December of 1965.
On June 3rd, 2017, a local news station, WGRZ-TV, reported on the history of the Kinzua Dam and the Seneca Nation. View that coverage here: https://youtu.be/ToGeLwIaP9w.
