About this map

Allegheny Reservoir dominates this landscape, its waters filling the valley floors between the steep ridges of the Allegheny National Forest. This 1960s survey documents the area shortly after the reservoir’s normal pool elevation reached 1328 feet, reshaping the geography of the Corydon and Hamilton regions. The iconic Cornplanter Bridge spans the narrowed northern reaches of the water, connecting the mountain roads above Kinzua Creek.

The map reveals a transition toward recreation in the mid-20th century, with numerous developed sites including Kiasutha Recreational Area, Kinzua Beach, and the Pine Grove Campground. Remnants of earlier extractive industry remain visible through scattered oil wells and a quarry near the Allegheny River. High points such as Kool Knob Lookout Tower and Jakes Rocks Overlook provide vantage points over the complex network of runs and creeks, including Mead Eddy Run and Chappel Fork, that feed the massive impoundment.
