Upper New York Bay, or Upper Bay, is the traditional heart of the Port of New York and New Jersey, and often called New York Harbor. It is enclosed by the New York City boroughs of Manhattan, Brooklyn, and Staten Island and the Hudson County, New Jersey municipalities of Jersey City and Bayonne.
It is fed by the waters of the Hudson River (historically called the North River as it passes Manhattan), as well as the Gowanus Canal. It is connected to Lower New York Bay by the Narrows, to Newark Bay by the Kill Van Kull, and to Long Island Sound by the East River, which despite the name, is actually a tidal strait. It provides the main passage for the waters of the Hudson River as it empties through the Narrows. The channel of the Hudson as it passes through the harbor is called the Anchorage Channel and is approximately 50 feet deep in the midpoint of the harbor. A project to replace two water mains between Brooklyn and Staten Island which will eventually allowing for dredging of the channel to nearly 100 feet (30 m) was begun in April 2012.
