The 5,900-acre park lies in the broad Bald Eagle Valley of northcentral Pennsylvania. Two geologic provinces create Bald Eagle's scenic beauty. The Allegheny Plateau to the north and west holds smooth, undulating uplands. The Ridge and Valley Province to the south and east contains numerous long, narrow mountain ridges separated by valleys. The lake, created by the Foster Joseph Sayers Reservoir, holds black crappie, largemouth and smallmouth bass, yellow perch and other warm water species. The lake also attracts snapping turtles, osprey, great blue heron and the occasional bald eagle. Motorboats must display a boat registration from any state.
