Maine River Flow Rates & Stream Gauge Data
Live USGS stream gauge data for Maine — current CFS flow rates, gauge heights, water temperatures, and wading conditions for Maine rivers and streams. Updated every 15 minutes. Know before you go.
Planning with Maine river conditions
Browse USGS monitoring stations across Maine rivers and streams. Each gauge page
shows current readings plus 7, 14, and 30-day flow-rate charts with condition indicators.
Compare the station name and location with your intended reach, then use the recent trend
alongside the current reading. Rain, snowmelt, dams, tributaries, and the distance between
stations can produce different conditions on the same river.
