Androscoggin River, River between New Hampshire and Maine, United States
The Androscoggin River originates at Umbagog Lake and travels roughly 178 miles through New Hampshire's White Mountains before flowing southeast into Maine and ending at Merrymeeting Bay. The waterway passes through forests and towns while providing a natural corridor through the region.
Eastern Abenaki people named this waterway Ammoscoggin, which originally referred to the section above Great Falls in Lewiston. The indigenous name has remained tied to the river throughout centuries of European settlement and industrial development.
The river shaped Berlin, New Hampshire and the Maine cities of Lewiston and Auburn, where mills once lined its banks. These towns grew as manufacturing centers powered by the waterway.
Multiple public access points allow visitors to reach the river for fishing and recreation. Spring through fall offers the best conditions for water activities, though water levels can vary seasonally.
The river drops sharply as it flows, creating powerful currents that once powered watermills throughout the region. This natural drop made it one of the most valuable energy sources in 19th-century New England.
