Providence River

The Providence River is a tidal river in the U.S. state of Rhode Island. It flows approximately 8 miles (13 km). There are no dams along the river's length, although the Fox Point Hurricane Barrier is located south of downtown, to protect the city of Providence from damaging tidal floods.

The southern part of the river has been dredged at a cost of $65 million in federal and state funds to benefit nearby marinas and commercial shipping interests.

Owing to Adriaen Block's exploration of Narragansett Bay, the Providence River (which the Dutch called the Nassau River) was the northeastern limit of Dutch claims in the colonial era from 1614 until the Hartford Treaty of 1650 and can therefore be regarded as the original boundary between the English New England colonies and the Dutch colony of New Netherland.
