The Allegheny Reservoir, extending into the greater Western portions of our Allegany Territory, has significantly changed the river's borders and boundaries. The Seneca Nation of Indians Geographic Information Services (GIS) Department has created a story map of aerial imagery of Ohi:yo' that shows the changes to the shoreline of Ohi:yo'.
Kinzua Dam was built by the U.S. Army Corps of Engineers between 1960 and 1966. Once it began operations in 1967, Ohi:yo' was only able to move up, spilling past its banks and inundating our land.
For the past five decades portions of Ohi:yo' have operated as a reservoir in the summer months. Come fall of every year, much of the water reserves are lowered at the discretion of the U.S. Army Corps of Engineers. Ohi:yo' now follows a new cycle, forming new shorelines with deadly ecological effects.
The main environmental impacts of Kinzua Dam are:- Harmful Algal Blooms (HABs)
- Riparian Zone Degradation
- Invasive Plant Species
- Degraded Fish Habitat
- Sedimentation
