Thames River

The Thames River is a short river and tidal estuary in the U.S. state of Connecticut. It flows south for through eastern Connecticut from the junction of the Yantic and Shetucket rivers at Norwich, to New London and Groton, which flank its mouth at Long Island Sound. The Thames River watershed includes a number of smaller basins and the 80-mile-long Quinebaug River, which rises in southern Massachusetts and joins the Shetucket River about four miles northeast of Norwich.HistoryThe river has provided important harbors since the mid-17th century. It was originally known as the Pequot River after the Pequot Indians who dominated the area. Other early names for the river have included Frisius, Great, Great River of Pequot, Little Fresh, Mohegan, New London, and Pequod. The town was officially named New London in 1658 and the estuary river was renamed Thames to match.The United States Coast Guard Academy, Connecticut College, a U.S. Navy submarine base, and the Electric Boat submarine shipyard are located on the river at New London and Groton. The USS Nautilus (SSN-571) was launched into the river on January 21, 1954 from Electric Boat, becoming the world's first nuclear-powered submarine.
