Currently only a small portion (2% of the Allegheny National Forest) is protected as wilderness. This includes 7 river wilderness islands and one of the last remaining old-growth forests in the eastern U.S. at the Hickory Wilderness. This was the only land left untouched from logging and represents Pennsylvania's last true wilderness. Largely due to the U.S. Forest Service's success in reclaiming the land, a proposal now stands before Congress to increase the wilderness area up to 10% of the forest, which is the U.S. average for national forests. Some success to this end has been achieved in the latest forest revision plan. The dam is 1,897 feet tall with the bulk of the structure, the earthfill, standing at 179 feet. There are 3,000,000 Cubic yards of concrete in it.
Continued from previous page control, hydroelectric power production and recreation The nearest city to the dam is Warren, Pennsylvania. Situated six miles east of the city on Route 59, the dam is open for public tours. It is located within the half-million acre Allegheny National Forest in northwestern Pennsylvania. A boat marina and beach are located nearby. A proposal to set aside a significant part of the land as wilderness in the 1990s was unsuccessful but did create the Allegheny National Recreation Area, comprising 23,000 acres which established the use of the area for camping, fishing, boating, hiking, canoeing and kayaking and other outdoor nature activities.
