Hendrick Island is a large erosional feature in Bucks County, Pennsylvania. Once part of the main shoreline, a sizable channel of the Delaware River now separates it from the rest of the state. The island is part of Solebury Township and a protected natural area within Delaware Canal State Park.
The 112 acre (45 ha) island supports a large deciduous forest, despite its somewhat sandy soil. Wildlife includes deer, which occasionally swim to the island from Pennsylvania; and squirrels. The shoreline is generally rocky, especially along the eastern coast and northern tip, and populated by several species of fish and water snakes. The more recently formed western coast is more irregular and less rocky than the eastern. The island tapers to another rocky point at its southern end, three-quarters of a mile downstream from the northern point.
Also uncommon among the islands of the Delaware, Hendrick Island has quite varied topography. The center of the island is about 15 feet (4.6 m) above the normal height of the river. As a result, there are two distinct ecological areas on the island: a flat, frequently submerged riparian habitat along the shore and a deciduous forest habitat farther inland typical of the terrain in the surrounding areas of Pennsylvania and New Jersey.
The only ways to the island are swimming or boating. Canoeists and kayakers have the option of launching from a small parking lot maintained by the Pennsylvania State Park Service adjacent to the north point of the island or from Bull's Island recreational area roughly one mile (1.6 km) upstream on the New Jersey shore of the river. A public boat launch several miles downstream in Lambertville, New Jersey makes a convenient place to take out a boat. Any unpowered boats launched from the parking lot on the Pennsylvania side require a launch permit from the Pennsylvania Fish & Boat Commission. Larger boats should not attempt to approach the island's rocky shore line. Boaters passing by the area of the island are best off going through the far eastern channel of the river between Eagle Island and New Jersey; the other two channels are frequently too shallow for safe passage.
The shoreline of the island constantly changes with the level of the river, so there is no one consistent best spot for landings, but the northern part of the western coast is generally the most favorable area. In low water conditions, it is often much easier to wade to the island from the Pennsylvania shore than attempt to boat over.
In 1955 the island was bought by PECO Energy, which was interested in constructing a hydroelectric power plant. However, the site was never developed and in 1996 the island was bought by the Bucks County Heritage Conservancy. Currently it is managed by the Pennsylvania Department of the Conservation of Natural Resources as a natural area within Delaware Canal State Park.
Since the floods of 2004-2005, the riparian areas of Hendrick Island have been choked by debris carried to the island from upstream, especially along the western shore. Though access to the interior of the island from the western shore is now limited, it appears that little ecological damage has been done.
