The Upper New York Bay is fed by the waters of the Hudson River, 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 its 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.

The harbor contains several islands including Governors Island, Ellis Island, Liberty Island, and Robbins Reef which are supported by a large underwater reef on the New Jersey side of the harbor.
