The Pawtucket River is a river located in the northeastern United States, primarily flowing through the state of Rhode Island. It originates from the confluence of the Blackstone River and the Moshassuck River and flows into Narragansett Bay. The river is approximately 10 miles long and serves as a natural boundary between the cities of Pawtucket and Central Falls. Historically, the Pawtucket River played a significant role in the industrial development of the region, particularly during the Industrial Revolution. The river's water power was harnessed for mills and factories, contributing to the growth of local economies. Today, it is a vital resource for recreation and wildlife, with parks and trails along its banks.
