Hills Creek Lake
The focal point of the park is a 137-acre lake developed by impounding Hills Creek. The earth dam, built by the Commonwealth of Pennsylvania, is 34 feet high and 422 feet long. The basin of Hills Creek Lake is long and narrow ending in an irregular triangle at the north end. The elevation is 1,486 feet and the nearby mountains rise to an elevation of 2,200 feet.
The temperatures and chemical characterizations of the lake support a good warmwater fishery.
The general area now covered by water has almost continually, since the end of the last ice age, been under the influence of beaver dams and beavers. Beavers still abound in the area, including in Hills Creek Lake. The depth of the beaver marsh (vegetation and sediment) is as great as 20 feet deep.
