MASSACHUSETTS FLOW REPORT

Last Updated: December 29, 2025

Massachusetts' rivers are currently experiencing a significant trend of below-average streamflows, as indicated by recent data across multiple waterways. Notably, the Merrimack River at Lowell shows a current streamflow of 2910 cubic feet per second (cfs), which is 80.7% below the norm, though its gage height remains at a considerable 42.45 feet. Similarly, the Connecticut River at Montague City is flowing at 2720 cfs, a stark 88.5% below what's typically expected, with a current gage height of 6.94 feet. The Nashua River at East Pepperell and the Concord River below River Meadow Brook are also running low at 198 cfs and 263 cfs respectively, which are more than 75% lower than average. Such conditions are critical for water enthusiasts to note as they may affect recreational activities and could indicate potential flow droughts in the area.

Elevated concerns arise around Holyoke, where the Connecticut River's flow has spiked by 23.93% in the last 24 hours, now at 10100 cfs, which could raise flooding concerns if such increases continue. Conversely, the Green River near Colrain is one of the few rivers slightly above normal at 6.1%, stable at 142 cfs. Whitewater trail enthusiasts should be cautious as these conditions fluctuate. Cities along these rivers, like Lowell and Holyoke, as well as watersheds of the Merrimack, Connecticut, and Nashua Rivers, should remain vigilant to changes that could impact water-based recreation and city water management. Steady monitoring of streamflows and gage heights is critical for both safety and ecological conservation in these regions.
