About

Through Providence County's mill corridor, the Blackstone River carries 580 CFS average on its 48-mile run toward Narragansett Bay. The upper stretch from Woonsocket to Central Falls runs Class I-II through the heart of what became the Blackstone River Valley National Historical Park, where stone mill foundations and raceways still line the banks. Below Central Falls, the gradient flattens to Class I as tidal influence begins to reach upstream. At optimal flows between 200-1200 CFS, the river offers a mix of moving water and industrial archaeology, with the Blackstone Valley Tourism Council and Blackstone Valley Paddle Club coordinating access and trips. The entire corridor holds designation as the Blackstone Heritage Corridor, protecting both the waterway and the mill sites that powered early American manufacturing. USGS gauge 01112500 tracks conditions for paddlers working this system.
