MAINE FLOW REPORT

Last Updated: December 29, 2025

The state of Maine is currently experiencing a notable trend of lower-than-average streamflows across several river systems, which may affect river and water enthusiasts looking for seasonal activities or monitoring potential environmental concerns. Rivers such as the St. John, Big Black, Allagash, and Aroostook are reporting streamflows significantly below their typical values, with the St. John River at Ninemile Bridge flowing at 843 cubic feet per second (cfs), a sharp 65.28% below normal. This trend of decreased flow extends to the Penobscot and Kennebec Rivers, important for both ecological health and recreational use. For instance, the Penobscot River at West Enfield is flowing at 9,570 cfs, which is 58.94% below its normal flow, potentially impacting communities and popular whitewater trails near West Enfield and The Forks, where the Kennebec River is also experiencing reduced flows.

In contrast, the Meduxnekeag River above the South Branch near Houlton has shown an unusually large increase, with streamflow surging to 591 cfs, a significant increase from its previous measurements and 24.31% above the norm, indicating a potential for flooding in the surrounding areas. The Wild River at Gilead has also seen a dramatic rise to 1,030 cfs, 86.39% above normal flow, which could affect areas around Gilead. Overall, the deviation from normal streamflows, both high and low, suggests a disruption in seasonal patterns that could impact river-based recreation, wildlife habitats, and community safety. Water and river enthusiasts, as well as local residents, should stay informed about current conditions and be prepared for the possible implications of these abnormal streamflows, including the risk of flow droughts and flooding events.
