On my travels I took a drive through the Allegheny National Forest on Route 59. I was particularly interested in the dam, which I did not remember viewing on a previous trip. Forest surrounds the 7,647-acre reservoir that spans the border between Pennsylvania and New York. In Pennsylvania, the reservoir is completely surrounded by the Allegheny National Forest, and in New York State by Allegany State Park and the Allegany Indian Reservation of the Seneca Nation. At normal summer pool level the reservoir is 27 miles long, 14 miles in Pennsylvania and 13 miles in New York, with 91 miles of shoreline, and a maximum depth of 130 feet.








The 862-acre Chapman State Park includes the 68-acre Chapman Lake on the West Branch of Tionesta Creek. Adjacent to state game lands and the Allegheny National Forest, Chapman is an oasis of recreational facilities in a vast area of wilderness. There is a lake with swimming, a campground and other activities available.
