MAINE FLOW REPORT

Last Updated: December 21, 2025

Streamflow levels across Maine's rivers are currently experiencing lower than normal conditions, which could impact various activities including fishing, boating, and white-water rafting. The St. John River at Ninemile Bridge, a significant waterway for northern Maine, is running at 843 cubic feet per second (cfs), which is 65.28% below the norm, indicating a potential for flow droughts in the region. Similarly, East Branch Penobscot River at Grindstone and the Big Black River near Depot Mtn have notably low flows at 943 cfs and 140 cfs, respectively, both more than 64% below their normal streamflow, affecting water-based recreation and ecology. Concerning changes have also been observed at the Piscataquis River Near Dover-Foxcroft, where a significant 24-hour increase of 539.3 cfs has been recorded, although the river remains 61.54% below its normal flow.

Major rivers such as the Penobscot at West Enfield and the Kennebec at North Sidney are exhibiting large streamflows of 16,000 cfs and 14,400 cfs, but are still 33.88% and 23.94% below normal, respectively. These decreases may signal flow irregularities that could affect cities like Auburn and ecosystems dependent on these water bodies. In stark contrast, the Wild River at Gilead has seen a massive surge in streamflow, with an increase of 932.06 cfs, reaching 1,030 cfs, which is 86.39% above normal, raising concerns for potential flooding in the area and impacting the popular white-water trails nearby. The Androscoggin River, a vital watershed for both recreation and industry, shows a mixed pattern with a decrease at Rumford and a substantial increase near Auburn, which could have implications for local communities. In summary, river conditions across Maine are highly variable, with several rivers facing low streamflows and others experiencing sharp increases, warranting attention from river enthusiasts and local authorities for potential environmental and recreational impacts.
