Van Sickle Island is an approximately 10,000-acre (4,000 ha) island in Suisun Bay, California. It is part of Solano County, and administered by Reclamation District 1607. Its coordinates are 38°04′00″N 121°54′04″W / 38.06667°N 121.90111°W, and in 1981 the United States Geological Survey recorded its elevation as 0 ft (0 m). The island's land is divided into 22 privately-owned parcels, used primarily for duck clubs and private residences. A railroad bridge constructed in 1913 once connected it to Montezuma and Chipps Island, from which a ferry connected to Mallard Island and Pittsburg. The rail service was discontinued and the bridges no longer exist; currently, the island is accessible by water, as well as by road on bridges from Hammond Island and Wheeler Island.
