Allagash River
About
From northern Maine's vast boreal forest, the Allagash runs 92 miles through the Allagash Wilderness Waterway as one of the original eight National Wild & Scenic Rivers. At 1,973 CFS average flow, with an optimal range of 975–2,950 CFS, this is big water by northeastern standards. The waterway designation protects the entire corridor from development, maintaining the dense spruce-fir canopy and undeveloped shoreline that defines the northern Maine wilderness experience. USGS gauge 01011000 tracks flows that can vary dramatically with snowmelt and seasonal patterns, making timing critical for trip planning.
River conditions are community-verified. CFS ranges, difficulty ratings, and access points may not reflect every flow level or seasonal change. Always check current conditions, scout unfamiliar rapids, and paddle within your skill level.
