CONNECTICUT FLOW REPORT
Last Updated: December 4, 2025
Streamflow conditions across Connecticut's rivers present a mixed picture for river enthusiasts, with certain waterways experiencing significant changes in flow. The Connecticut River at Middle Haddam currently flows at 22,200 cubic feet per second (cfs), a modest increase over the last 24 hours, though this flow rate is somewhat below normal for the area. In contrast, the Hockanum River near East Hartford has dropped sharply to 116 cfs, a 58.27% decrease and substantially below its average flow. This could signal potential flow drought conditions that merit monitoring. On the other hand, the Shetucket River at Taftville has surged to 1,260 cfs, which is 19.11% above the norm, indicating a large influx that could raise concerns for possible flooding in nearby areas if such trends continue.
For whitewater enthusiasts, changes in the Farmington River are particularly noteworthy. At Unionville, the streamflow decreased slightly to 485 cfs, while at Tariffville, the streamflow increased to 810 cfs. Both locations are experiencing lower-than-average flows, which will affect the conditions on popular paddling courses. In the Quinebaug and Housatonic watersheds, river flows are fluctuating as well, with the Quinebaug River at Jewett City rising to 1,580 cfs, a marked increase that could affect river-based activities. Meanwhile, the Housatonic River at Stevenson is flowing at a mere 455 cfs, which is substantially below its usual level, indicating a low-flow period for the area. These variations underscore the dynamic nature of river conditions in Connecticut and the importance for river users to stay informed on current and forecasted streamflows for safety and enjoyment.
Connecticut has two main watersheds: the Connecticut River that flows from the northern border down to Long Island Sound, and the Housatonic River that flows from the western border before emptying into Long Island Sound. There are several large reservoirs and dams in the state, including the Barkhamsted Reservoir and Colebrook River Lake. Climate conditions in Connecticut vary from warm and humid summers to cold and snowy winters, which directly impact snowpack and streamflow. Additionally, Connecticut is susceptible to hurricanes and tropical storms, which can cause significant flooding. Connecticut's hydrology is highly influenced by the state's relatively small size, densely populated urban areas, and topography. The state's major rivers and tributaries are closely monitored by the USGS for water quality and quantity.
