The Pawcatuck River is a river in the US states of Rhode Island and Connecticut flowing approximately 34 miles (55 km).[2] There are eight dams along the river's length.[3]USS Pawcatuck was named after the river.
On April 20, 2006, an Atlantic white-sided dolphin swam several miles up the river to Westerly, Rhode Island, from Little Narragansett Bay at the east end of Fishers Island Sound. It spent several hours at Westerly-Pawcatuck, near the bridge connecting Rhode Island and Connecticut, while several hundred spectators gathered to see it. According to the Mystic Aquarium, the dolphin may have become separated from its pod at sea and had been searching for it. It was captured and taken later that night to the aquarium, where it died; it had become sick, underweight, and bruised during its journey upriver.[4]
The Pawcatuck River flooded during a fierce rainstorm in New England on March 29, 2010, with waters overflowing into both Westerly and Pawcatuck. Both towns evacuated low-lying areas, and some historic buildings were lost to flood damage along the course of the river, and its tributaries such as a 150-year-old general store in North Stonington adjacent to the Shunock River.[5] The bridge in downtown Westerly-Pawcatuck was closed for several weeks until the river had gone down enough for divers to inspect it for safety.[5]
