RHODE ISLAND FLOW REPORT
Last Updated: December 27, 2025
Rhode Island's river enthusiasts should pay close attention to the latest streamflow data, which reveals a general trend of below-normal water levels across the state's major waterways. The Branch River at Forestdale, Blackstone River at Woonsocket, South Branch Pawtuxet River at Washington, Pawtuxet River at Cranston, Blackstone River at Roosevelt Street in Pawtucket, and Pawcatuck River at Westerly are all experiencing significantly reduced streamflows, with percentages ranging from -23.51% to a stark -73.35% of normal levels. The Pawcatuck River, at a current streamflow of 248 cubic feet per second (cfs) and a 4.98 cfs reduction over the last 24 hours, is notably at 73.35% below its normal flow, indicating potential flow drought conditions that could impact the surrounding Westerly area.
Several rivers, including the Branch River and Blackstone River, show declines in streamflow over the last day, with the former dropping by 3.01 cfs and the latter by 7.37 cfs. The Pawtuxet River at Cranston, which flows near a densely populated area, has also seen a decrease in streamflow by 3.77 cfs, currently flowing at 153 cfs, which is 69.47% below the expected norm. This could affect water-dependent activities and ecosystems. With gage heights ranging from 1.27 meters at the Blackstone River at Pawtucket to 4.2 meters at the Pawtuxet River in Cranston, river users and adjacent communities should remain vigilant for any sudden changes that could indicate flooding, especially during seasonal weather shifts. While the current data does not point to immediate flood risks, the consistently low streamflows across these rivers highlight the need for careful monitoring, especially for whitewater trails which may be negatively impacted by the decreased water levels.
Rhode Island is a state with a humid continental climate characterized by short, mild summers and cold winters. Major surface flows include the Blackstone, Pawtuxet, and Woonasquatucket Rivers, as well as the Narragansett Bay. The state has over 3,000 freshwater lakes, ponds, and reservoirs, many of which are man-made. Notable dams include the Scituate Reservoir and the Pawtuxet Dam. The state's hydrology is influenced by precipitation patterns and snowmelt, with winter snowpack contributing to spring runoff. Rhode Island has experienced an increase in extreme precipitation events in recent years, leading to flooding and erosion. Watershed management and climate change adaptation are important considerations for maintaining healthy surface water resources in the state.
