Bald Eagles at Sinnemahoning State Park: The Comeback in Our Valley
On a quiet morning at the George B. Stevenson Reservoir, a bald eagle drops from a dead snag, skims the water, and climbs away with a fish. In Sinnemahoning, that isn't a once-in-a-lifetime moment. A pair of eagles has called this lake home year-round since 2000, and the First Fork valley is now one of the best places to see bald eagles in the PA Wilds.
Bald eagles at Sinnemahoning State Park
Sinnemahoning State Park stretches along the First Fork of Sinnemahoning Creek in Cameron and Potter counties, about a 25-minute drive up PA 872 from the village. At its south end, the George B. Stevenson Dam holds back a 145-acre lake, and that lake is what drew the eagles in.
The park's resident pair settled here in 2000 and has stayed year-round ever since. By 2007, a wildlife photographer noted that the eagles had been nesting in the same part of the lake for a number of years. Eagles sometimes build new nests, and by 2016 the park was inviting visitors to watch "the newest eagle nest." Today the park's active nest is visible from a public viewing area, so you can watch a wild eagle family from a respectful distance.
Where to see bald eagles near Sinnemahoning
- The boat launch and Eagle Watch Picnic Ground. The resident pair can be seen year-round around the boat launch area. A pavilion sits right above the launch, so pack a lunch and keep your binoculars handy.
- Below the dam. In winter, eagles fish the open water below the George B. Stevenson Dam.
- The Wildlife Viewing Area. At the north end of the park, near the Wildlife Center, the viewing area looks out on the park's active nest. It's wheelchair accessible, and the viewing blind also overlooks fields where deer and elk graze.
- 40 Maples Day Use Area. Named for the rows of maples planted by early game protector Chauncey Logue, it's one of the best places in the park to spot eagles.
- The Wildlife Center. Start here. The hands-on exhibits include a life-size replica of a bald eagle nest, so the kids can see just how big one is.
Keep an eye on the sky, too. Golden eagles are sometimes seen soaring over the valley.
Free Eagle Watch days at Sinnemahoning State Park
Every spring, the park hosts free Eagle Watch afternoons at the Wildlife Viewing Area gazebo. Park volunteers set up binoculars and spotting scopes trained on the active nest, so you get a close-up look without getting close. In 2026 the sessions ran on Saturdays in April from noon to 2 p.m. In late May, when the eaglets are almost as big as their parents and getting ready to fly, the park has held Eagle Nest Watch days too.
In February, the park has also hosted eagle watches at the lake during the Great Backyard Bird Count, with a park naturalist and scopes on hand to help you pick out wintering bald and golden eagles.
Dates change each year, so check the DCNR events calendar or call the park before you go.
Best time to see bald eagles in the PA Wilds
- January–March: The pair bonds and repairs the nest. One to three eggs are laid in March.
- Mid-April: The eaglets hatch, and the Eagle Watch season begins.
- June: The young eagles usually fledge and take their first flights.
- Fall: Migrating eagles stop to rest and feed on the lake, right as the foliage peaks.
- Winter: Look for eagles fishing below the dam or feeding along the roadside.
With a good pair of binoculars and some patience, you can see eagles here in any month.
Eagles beyond the park
The eagles don't stay inside the park lines. In the late 2000s, a Game Commission officer spotted a pair of mature bald eagles in a sycamore along the Driftwood Branch of Sinnemahoning Creek, a sign that more eagles were moving into Cameron County. Scan the big trees along the creeks as you drive Route 120, and watch for a flash of white over the water.
How eagles came back to Pennsylvania
As recently as 1983, Pennsylvania had only three known eagle nests left, after DDT and polluted water wiped out most of the state's eagles. From 1983 to 1989, the Game Commission brought 88 eaglets from Saskatchewan and released them along the Susquehanna River and in the Poconos. The DDT ban and cleaner rivers did the rest. Today the state has more than 300 nests, and the bald eagle has been off the endangered list since 2007. Sinnemahoning's pair is part of that comeback.
Bald eagle viewing tips
- Stay at least 1,000 feet from a nest. Use the viewing area, binoculars, or a spotting scope.
- Never make an eagle fly. An eagle flushed from its nest leaves its eggs or chicks exposed.
- Use your car as a blind, keep your voice down, and move slowly.
- Back away if an eagle calls repeatedly or starts to move off. That means you're too close.
- Stick to public viewing areas and respect any posted closures. Disturbing a nesting eagle is against the law.
