Reynolds Channel is a strait in Nassau County, New York that separates Long Beach Barrier Island, which contains the City of Long Beach and the villages of Atlantic Beach, Lido Beach, and Point Lookout, from Long Island, Barnum Island, Harbor Isle, and various uninhabited islands between Long Beach Island and Long Island. The channel begins at the East Rockaway Inlet to the west, and ends at Point Lookout to the east, where it merges with the Jones Inlet.
The channel is named after William H. Reynolds, a developer and former State Senator who greatly built up Long Beach Island in the early 20th century.
The East Rockaway Inlet is an arm of the Atlantic Ocean which separates the Rockaway Peninsula from the barrier island which includes the Nassau County, New York communities of Atlantic Beach, Long Beach and Lido Beach. The inlet is on the south shore of Long Island. It provides for a channel 12 feet deep and 250 feet wide. A 3,000 foot jetty on the western side of the channel was authorized but never constructed, and was eventually deauthorized by Congress in 1977.
According to a plaque in Long Beach, New York, the original inlet was through Long Beach directly opposite East Rockaway. New York, hence the name. A decision was made to create a new inlet between Far Rockaway, New York, and Atlantic Beach and the original was filled in with the fill from the newly created inlet.
