MASSACHUSETTS FLOW REPORT

Last Updated: December 21, 2025

Massachusetts river enthusiasts should take note of the current waterway conditions, which indicate a diverse range of streamflow trends across the state. The Merrimack River near Lowell presents a significant volumetric flow of 4,720 cubic feet per second (cfs), although it's running at 61% below its normal flow, which could affect recreational activities negatively. In contrast, the Connecticut River at Montague City exhibits a healthier flow near normal levels, with a noteworthy 24-hour increase to 18,000 cfs, raising the gage height to 13.14 feet, which should be closely monitored for potential flooding implications. Rivers popular for whitewater activities, such as the Deerfield River and Westfield River, are experiencing declines in streamflow, with the former near West Deerfield dropping by 29.2 cfs, possibly affecting the difficulty level of rapids.

Cities along these rivers, including Lowell, Holyoke, and Fitchburg, should stay alert as changes in river levels could impact urban waterways and adjacent areas. The Blackstone River at Northbridge is one of the few rivers flowing above normal at 5.98%, which could be favorable for activities that depend on higher water levels. However, several rivers are experiencing flow droughts, such as the Sudbury River at Saxonville and the Charles River at Waltham, with streamflows at 63.87% and 71.62% below normal, respectively, which might impact water supply and local ecosystems. Notably, the West Branch Farmington River near New Boston saw a dramatic 24-hour increase of 352.49 cfs, possibly indicating runoff events or upstream releases, and should be watched for rapid changes. Water enthusiasts and riverside communities should stay informed on current streamflow conditions and remain vigilant for potential flooding or low-flow issues affecting accessibility and safety along Massachusetts' diverse and scenic waterways.
