Susquehanna Riverlands

Susquehanna Riverlands State Park (formerly known as Susquehanna Riverlands Environmental Preserve) is a 449-acre park in York County, Pennsylvania, located along the lower Susquehanna River near the Brunner Island steam electric station. The park was developed through a partnership between PPL Corporation (the power plant operator) and the Pennsylvania DCNR to transform former industrial land and floodplain into a public nature preserve. The park features wetlands, meadows, bottomland forest, and river access, providing a natural oasis in the industrialized lower Susquehanna corridor between York and Lancaster counties.

The park's combination of restored wetlands, meadows, and river frontage creates excellent wildlife habitat. The Susquehanna River supports smallmouth bass, channel catfish, and seasonal runs of American shad and river herring. Bald eagles are regularly observed, often perching near the warm water discharge from the adjacent power plant, which keeps the river open in winter and concentrates fish. Great blue herons, ospreys, and double-crested cormorants frequent the river. The wetlands attract migrating waterfowl, shorebirds, and various amphibians. The meadows support eastern bluebirds, tree swallows, and butterflies. The park has become one of the best birding locations in the lower Susquehanna Valley, with over 200 species recorded.

The park's landscape is a mix of restored wetlands, native meadows, bottomland forest, and riparian vegetation. The wetlands support cattails, bulrush, sedges, and aquatic plants that provide cover for wildlife. Native warm-season grass meadows have been established on former agricultural and industrial land, supporting goldenrods, asters, milkweed, and other wildflowers. The bottomland forest includes sycamores, silver maples, green ash, and cottonwoods along the river. Upland areas feature oaks, maples, and tulip poplar. The park's restoration plantings have created a diverse mosaic of habitats from what was previously degraded land, and the vegetation continues to mature and diversify over time.

The park occupies a broad floodplain and river terrace along the lower Susquehanna River, where the river flows through the Piedmont Province toward its eventual discharge into the Chesapeake Bay. The underlying bedrock consists of Paleozoic-age metamorphic rocks including schist and gneiss, overlain by thick deposits of river alluvium — gravel, sand, silt, and clay carried and deposited by the Susquehanna over millennia of flood events. The flat terrain reflects the river's depositional processes. Upstream, the Susquehanna passes through Conewago Falls, one of the few remaining natural rocky rapids on the lower river, which historically served as a major fishing site for indigenous peoples and early settlers.

The park experiences a humid subtropical climate, relatively mild by Pennsylvania standards. Winter temperatures average in the mid-20s to mid-30s Fahrenheit, with 20 to 30 inches of snowfall. The warm water discharge from the adjacent Brunner Island power plant keeps portions of the river ice-free in winter, attracting eagles and waterfowl. Summers are warm and humid with highs in the mid-80s to low 90s. Annual precipitation averages approximately 40 to 44 inches. Spring flooding is a periodic occurrence, and the park's floodplain location means some areas may be inundated during high water events. The long growing season supports diverse plant and wildlife communities.

The lower Susquehanna River Valley was the homeland of the Susquehannock people, who maintained major villages and fishing stations along the river. European colonists, including William Penn's settlers, established farms and mills in the area beginning in the late 17th century. The Susquehanna River served as a major transportation corridor, with canal boats, rafts, and later railroads carrying coal, timber, and goods through the valley. The Brunner Island power plant was built in the mid-20th century, altering the river's thermal regime and the surrounding landscape. The creation of the park represents a more recent chapter, as formerly industrial and agricultural land was restored for conservation and public access.

Susquehanna Riverlands was developed through an innovative partnership between PPL Corporation and the Pennsylvania DCNR, transforming former industrial land adjacent to the Brunner Island power plant into a public nature preserve. The restoration involved wetland creation, native meadow establishment, tree planting, and trail construction. The park opened to the public as an environmental education and recreation area, with an emphasis on wildlife observation and nature study rather than traditional active recreation. The partnership model demonstrated how energy companies and conservation agencies can collaborate to create public environmental amenities from former industrial sites.

The park features approximately 5 miles of trails through wetlands, meadows, and bottomland forest, with observation platforms and wildlife viewing blinds positioned for optimal birding. The restored wetlands are a primary attraction, hosting diverse waterfowl, shorebirds, and wading birds, particularly during spring and fall migration. A river access point allows fishing and kayak launching on the Susquehanna. Interpretive signage explains the park's ecological restoration and the natural history of the river corridor. The warm water plume from the power plant creates year-round open water that concentrates eagles and fish, making winter birding particularly productive. The park hosts seasonal guided walks and educational programs.

Susquehanna Riverlands State Park is located off Route 30 near the village of York Haven in York County, approximately 10 miles south of Harrisburg and 15 miles north of York. The park has a parking area, portable restrooms, and trail access. An environmental education center provides seasonal programming. Facilities are relatively minimal, focused on nature observation rather than active recreation. The park is open year-round for day use. The nearest services are in York Haven and Goldsboro. The park is accessible from I-83 and Route 30, making it convenient for day trips from the Harrisburg and York metropolitan areas.

Susquehanna Riverlands represents a successful model of ecological restoration on former industrial land. The created wetlands provide water filtration, flood attenuation, and critical wildlife habitat along the Susquehanna River corridor. Ongoing management includes invasive species control, native planting maintenance, and water quality monitoring. The park's location on the Susquehanna makes it a relevant site for monitoring the river's ecological health, including fish migration, eagle populations, and water quality trends. The partnership between the energy company and the state continues to support management and educational programming. The park contributes to the broader effort to restore and protect the Susquehanna River watershed, which drains into the Chesapeake Bay.
