MASSACHUSETTS FLOW REPORT

Last Updated: January 11, 2026

In Massachusetts, river enthusiasts should be aware of the varying streamflow trends that could impact both recreational activities and environmental conditions. Currently, the Merrimack River at Lowell exhibits a significant decrease in streamflow, running at 4,170 cubic feet per second (cfs), which is 55.98% below the norm, signaling potential flow droughts. Contrastingly, the North Nashua River near Leominster has seen a notable 104.72% increase in streamflow over the last 24 hours, though it remains 10.55% below normal. The Connecticut River, a major waterway traversing through Holyoke and Montague City, is flowing at 8,860 cfs and 9,350 cfs respectively, having risen by 10.2% and 111.54% in the last day, yet still remains below average by 44.07% and 35.36%. Whitewater enthusiasts should note the changes in the Deerfield River, with the site near West Deerfield rising by 60.19% to a current flow of 1,650 cfs.

Some rivers have seen streamflows dip to worrying levels, which could affect cities and local ecosystems. The Nashua River at East Pepperell, for example, has decreased to 264 cfs, a significant 63.11% below normal. The Sudbury River at Saxonville also has a reduced flow rate, currently at 203 cfs, down by 16.94%. The Assabet River at Maynard, crucial for local biodiversity, is running at 162 cfs with a recent 65.64% increase but is still 39.74% below the normal flow. The popular whitewater trail at the Deerfield River at Charlemont should be approached with caution as the streamflow is slightly below normal by 5.76%, though a minor rise in the last 24 hours could indicate improving conditions. In locations like the Chicopee River at Indian Orchard and the Neponset River at Milton Village, significant decreases in flow by 50.12% and 20.84%, respectively, could signal potential drought conditions and impact water-related activities. River users and residents should stay updated on these trends for the safety and enjoyment of Massachusetts' rivers and streams.

       



Massachusetts has a humid continental climate with warm summers and cold winters. Major surface flows include the Connecticut, Merrimack, and Charles Rivers, which all have numerous tributaries. The state has several large reservoirs and dams, including the Quabbin Reservoir and the Wachusett Reservoir. The hydrology of Massachusetts is influenced by its varied topography and abundant precipitation, which is evenly distributed throughout the year. Snowpack accumulation in the mountainous areas can impact river flows during the spring snowmelt. In recent years, Massachusetts has experienced more frequent and intense precipitation events, leading to increased flooding and erosion. The state has implemented various measures to manage its water resources, including water conservation programs and the construction of stormwater management systems.


       

Winter Storm Warnings

January 11 2026

Residents of Massachusetts, particularly those in western Franklin, Hampden, and Hampshire counties, should exercise caution due to hazardous weather conditions. The National Weather Service has issued wind advisories for these areas, with west winds of 15 to 25 mph and gusts up to 50 mph expected, potentially resulting in downed tree limbs and power outages. Additionally, a Special Weather Statement warns of black ice on roadways and walkways, as freezing temperatures may lead to icy surfaces. Berkshire County also faces similar risks. Motorists and pedestrians are advised to be vigilant, especially when traveling this morning as conditions improve with rising temperatures.
