1966 Map of Cornplanter Run

About this map

The Allegheny Reservoir dominates this 1973 photorevised landscape, showing the massive impact of the Kinzua Dam on the valley along the New York and Pennsylvania border. This era marks a significant transformation for the region, with the reservoir's waters at Normal Pool Elev 1328 submerging former valley floor lands once occupied by the Seneca Nation and local settlers. The Allegany Indian Reservation and the Allegheny National Forest meet here, with recreation sites like Willow Bay Recreation Area and Hooks Brook Campground replacing older river-bottom uses. Evidence of the region’s resource history remains visible through numerous Oil Wells and gas wells scattered across the upland ridges. Local history is anchored by the Riverview-Corydon Cem and numerous named drainages like Cornplanter Run and Hodge Run that feed into the expansive new lake system.
