The Ten Mile River is a river within the U.S. states of Massachusetts and Rhode Island. It flows approximately and drains a watershed of .[1]
The North Attleborough National Fish Hatchery is located in its upper reaches, and the river offers stocked trout fishing in the spring.
The Ten Mile River was badly polluted in the mid 1900s but has subsequently been remediated. Although there are still issues with metals and sediments in the water, the river and nearly all its tributaries are now designated as Class B waters (fishable, swimmable).
The river begins at Savage Pond, near the corner of High and Chestnut Streets, in Plainville, Massachusetts. From there, it flows generally south through North Attleborough, Attleboro and Seekonk before entering Rhode Island and flowing through Pawtucket and East Providence where it flows over the Omega Dam into the Seekonk River.
