RHODE ISLAND FLOW REPORT
Last Updated: December 19, 2025
Rhode Island's river enthusiasts should note the recent trends in the state's streamflow data, which reveal significant deviations from normal flows across several key waterways. The Branch River at Forestdale, Blackstone River at Woonsocket, South Branch Pawtuxet River at Washington, Blackstone River at Roosevelt Street in Pawtucket, and Pawcatuck River at Westerly are currently experiencing reduced streamflows, with the Blackstone River at Woonsocket reporting a current flow of 390 cubic feet per second (cfs), which is 72.27% below normal, and a similar downturn at Pawtucket with a flow of 412 cfs or 72.79% below normal. These figures may impact activities along these rivers, ranging from recreational use to the ecological health of the basins.
Specifically, the South Branch Pawtuxet River at Washington saw a significant 24-hour increase in streamflow of 110.12%, now flowing at 108 cfs, though it remains 52.13% below the norm, potentially indicating a flow drought recovery that requires monitoring for any risk of flooding. The Pawcatuck River, known for its recreational appeal, is at a gage height of 3.78 feet with a slight increase in flow, yet still 72.49% below normal, which could affect whitewater conditions. With these changes, residents and visitors along the Branch River, and cities like Woonsocket, Pawtucket, and Westerly should stay updated on water levels, especially those engaging in water-based activities, as the waterways continue to show variability in streamflow patterns.
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.
