East River
The East River is a tidal strait in New York City. It connects Upper New York Bay on its south end to Long Island Sound on its north end. It separates Long Island from the island of Manhattan and the Bronx on the North American mainland. In reference to its connection to Long Island Sound, it was once also known as the Sound River. The tidal strait usually reverses flow four times a day.The above text is a snippet from Wikipedia: East River
