It is an easy hike through thick spruce, grassy openings, vernal ponds, streamside bottoms and ends at the Wildlife Viewing Area at the north end of the park. There are lots of opportunities along this trail to spot grassland birds, osprey, elk and butterflies.

George B. Stevenson Dam

In 1955, the Commonwealth of Pennsylvania constructed the George B. Stevenson Dam on the First Fork Sinnemahoning Creek as a unit of the general comprehensive plan for flood control along the West Branch Susquehanna River Basin. This plan consists of four reservoirs: George B. Stevenson, Alvin R. Bush (Kettle Creek State Park), Curwensville and Foster Joseph Sayers (Bald Eagle State Park). Coordinated operation of the four reservoirs controls a total of 1,163 square miles of drainage area. By controlling the runoff from these areas, these reservoirs provide significant flood prevention to the towns downstream.

In order to achieve best results from the system, all four dams are regulated during floods in accordance with instructions issued by the Baltimore District, U.S. Army Corps of Engineers.

Statistics of George B. Stevenson Dam

  • Rolled, earth-fill structure 1,918 feet long
  • Maximum height of 166 feet
  • Top width of 30 feet and a maximum width of 940 feet at the base
  • A 16-foot diameter reinforced concrete tunnel carries the flow of the creek through the right (west) abutment of the dam
  • The 211-foot high reinforced concrete control tower houses the two, 37-ton sluice gates and operating equipment
  • The conservation pool is maintained at elevation 921 feet above mean sea level (m.s.l.)
  • The reservoir has a flood control storage capacity of 75,800 acre-feet (24.7 billion gallons), a surface area of 1,470 acres, and a length of 8 miles.
  • The flood control storage of the reservoir is equal to 5.85 inches of runoff from the 243-square mile drainage area above the dam.
