Long Island Sound is one of the Atlantic region’s most important estuaries. The sound separates New York and Connecticut and also forms a border between New England and the Mid Atlantic region.

At the sound’s upper end, currents from the estuary merge with Block Island Sound and the North Atlantic, forming strong tide rips. At its lower terminus, the East and Hudson rivers merge to form Upper New York Bay.

Long Island Sound is used by a wide range of commercial fishing vessels. On Long Island, Montauk Point is home to New York’s largest commercial fishing fleet.

Long Island Sound is one of the 28 nationally-designated estuaries under the the Environmental Protection Agency’s (EPA) National Estuary Program (NEP).
