CONNECTICUT FLOW REPORT

Last Updated: January 1, 2026

Streamflow conditions across Connecticut's rivers present a varied picture, with many rivers experiencing below-normal flows that could affect recreational activities and water resource management. The Connecticut River, a major waterway through the state, shows a significant streamflow at Middle Haddam with a current rate of 15,300 cubic feet per second (cfs), though this is still 43.7% below the seasonal norm. Similarly, the Connecticut River at Thompsonville is flowing at 15,700 cfs, 37.37% under typical levels. These low flows could impact boating and fishing enthusiasts, as well as the health of aquatic ecosystems. Conversely, an abrupt 59.71% increase in streamflow in the past 24 hours at Middle Haddam could signal potential for flooding, warranting caution for communities and outdoor enthusiasts alike.

Drastic reductions in streamflow are also seen in rivers such as the Farmington at Unionville, flowing at just 495 cfs, nearly 54% below normal, and the Quinnipiac River at Wallingford with a flow of 156 cfs, down 55.26%. These low flows may indicate flow droughts that could affect water availability and river health. The notable decrease in the Housatonic River at Stevenson by 87.25% from the normal flow rate is particularly concerning for both the ecological balance and recreational use, including popular whitewater trails near this watershed. These trends underscore the importance of monitoring streamflow data to anticipate and mitigate potential flooding, manage water resources effectively, and ensure the safety and enjoyment of Connecticut's river and water enthusiasts.

       



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.


       

Winter Storm Warnings

January 1 2026

Connecticut residents, particularly those in Eastern Windham County and New London County, are advised to exercise extreme caution as the National Weather Service has issued a Snow Squall Warning and Winter Weather Advisories in effect today. The Snow Squall Warning, in place until 9:15 AM EST, warns of whiteout conditions with near-zero visibility, intense snow bursts, and gusty winds leading to blowing snow, making travel difficult and dangerous. Additionally, a Winter Weather Advisory is active until 1:00 PM EST, forecasting slippery road conditions due to up to one inch of additional snowfall and wind gusts as high as 35 mph. Both advisories highlight hazardous conditions that could impact morning commutes. Residents should stay informed, avoid unnecessary travel, and prepare for sudden changes in weather.
