This dam is also the boundary between fresh and salt water.
The river continues to Pettaquamscutt Cove then out to Narragansett Bay.
The Pettaquamscutt River is also commonly known as the Narrow River, both because of a long narrow stretch from Lacy bridge to the Mettatuxett Yacht Club as well as the narrow, hazardous mouth of the river where it empties into Narragansett Bay.
The river is composed of at least five distinct sections, running from north to south: the upper pond, the lake, the narrows, the flats, and the mouth.
