MAINE FLOW REPORT

Last Updated: December 12, 2025

Maine's river and stream conditions are currently displaying a trend of decreased streamflow across the state, impacting river enthusiasts and potentially affecting various watersports activities. Notably, the majority of monitored sites are reporting streamflow rates significantly below their normal values, with the Mattawamkeag River near Mattawamkeag registering a streamflow change of +5.61 cfs but still remaining 72.9% below normal. The Piscataquis River near Dover-Foxcroft exhibited the largest increase in streamflow over the last 24 hours with a rise of 24 cfs, yet it still flows at 77.04% below its typical rate. These low streamflow conditions are widespread, with major rivers such as the St. John River at Dickey (1600 cfs, -61.92% normal), Penobscot River at West Enfield (5940 cfs, -62.64% normal), and Kennebec River at North Sidney (2900 cfs, -74.29% normal) also experiencing significant reductions in flow.

The current state of these rivers suggests flow drought conditions that might affect whitewater trails and recreational water use. However, the Sandy River near Mercer and the Carrabassett River Near North Anson, despite showing an alarming -86.3% and -86.71% from normal flow rates, respectively, have experienced increases in streamflow over the last 24 hours, which could signal the beginning of a trend reversal but still require monitoring for potential flood conditions. The Androscoggin River near Auburn remains steady with no change in the last 24 hours, although it flows at 69.02% below its normal rate, which could impact cities like Auburn and Rumford. Water enthusiasts should be aware of these conditions, particularly the significantly low flow rates, and should stay informed on the latest river data before planning any river-related activities.
