Tucked away in the heart of Pennsylvania’s remote and rugged Cameron County lies the George B. Stevenson Dam, a vital piece of infrastructure and a hidden gem for outdoor enthusiasts. Completed in 1955, the dam was constructed by the U.S. Army Corps of Engineers as part of a broader federal initiative to manage flood control in the Susquehanna River Basin. It was named after George B. Stevenson, a prominent local state legislator and conservationist who championed the protection and development of Pennsylvania’s natural resources.
Located within the boundaries of Sinnemahoning State Park, the earthen dam spans the First Fork of the Sinnemahoning Creek, a tributary of the West Branch of the Susquehanna River. Standing 166 feet high and stretching over 1,600 feet across, the dam created a 142-acre lake known as the George B. Stevenson Reservoir. This reservoir not only functions as a flood mitigation tool but also serves as a recreational haven for locals and visitors alike.
The reservoir provides excellent opportunities for fishing, kayaking, and canoeing, as gasoline-powered boats are prohibited to preserve the lake’s tranquility and ecological health. Anglers can expect to catch species such as largemouth bass, bluegill, perch, catfish, and stocked trout. In the winter months, the lake becomes a hotspot for ice fishing and scenic cross-country skiing.
Surrounding the reservoir is a diverse forest habitat that supports wild elk, black bears, white-tailed deer, bald eagles, and migrating waterfowl. Several hiking trails, including the Lowlands Trail and the Lakeview Trail, provide panoramic views of the reservoir and access to the park’s varied ecosystems.
In addition to its recreational appeal, the Stevenson Dam continues to serve its original purpose: regulating water flow to prevent downstream flooding. Over the decades, it has protected numerous communities along the Sinnemahoning Creek and the larger Susquehanna watershed.
Today, the George B. Stevenson Dam and its reservoir stand as a testament to the balance between engineering, conservation, and recreation. They offer not just safety from floods, but a peaceful retreat in one of Pennsylvania’s most remote and beautiful counties.
