About Ammonoosuc River

Flows west from Twin Mountain toward the Connecticut River. A mix of stocked and wild fish; the upper river near Twin Mountain runs cold and clear from White Mountain headwaters. The gauge at Bethlehem Junction reads the productive middle river well. Some fly-fishing-only regulations apply in upper sections — verify current NH F&G regs.
