NEW HAMPSHIRE FLOW REPORT
Last Updated: January 11, 2026
New Hampshire's rivers are experiencing varied streamflow conditions as the seasons shift, with certain rivers notably below their normal flow levels. For example, the Androscoggin River near Gorham is flowing at 1820 cubic feet per second (cfs), which is 37.56% below the norm for this time of year, and the Saco River near Conway is at only 30.51% of its average flow. Meanwhile, the Bearcamp River at South Tamworth shows an extraordinary increase, flowing at a staggering 400.78% above the normal with a current streamflow of 1630 cfs, which may raise concerns about potential flooding for the adjacent areas and could affect popular whitewater trails. Water enthusiasts should take note of these conditions, as they can significantly impact outdoor activities.
Further analysis reveals that the Connecticut River at North Stratford presents an above-average streamflow of 4920 cfs, which is 102.58% of its normal flow, possibly indicating a healthy watershed in that region. In contrast, rivers such as the Pemigewasset at Plymouth and the Upper Ammonoosuc near Groveton are at 1860 cfs and 1270 cfs, respectively, showing variations around their expected flows with the former slightly above and the latter significantly below. Cities along these rivers, including Groveton, Plymouth, and surrounding areas, should remain vigilant as these fluctuations can affect water availability and riverine ecosystems. River enthusiasts, especially kayakers and fishers, should monitor these trends closely for safety and optimal river use.
New Hampshire has a humid continental climate with cold winters and warm, humid summers. Major surface flows include the Connecticut River, which forms the western border of the state, and the Merrimack River, which flows through the central part of the state. The Pemigewasset, Saco, and Androscoggin Rivers are also significant. There are numerous reservoirs and dams in the state, including the Amoskeag Dam on the Merrimack River. Hydrology in New Hampshire is influenced by precipitation patterns, which vary widely across the state. Snowpack in the winter months is a major source of water for rivers and streams in the spring and summer. The state's many watersheds, including the Connecticut River watershed, play a critical role in determining flow conditions.
