Hawaii River Flow Rates & Stream Gauge Data
Live USGS stream gauge data for Hawaii — current CFS flow rates, gauge heights, water temperatures, and wading conditions for Hawaii rivers and streams. Updated every 15 minutes. Know before you go.
Planning with Hawaii river conditions
Browse USGS monitoring stations across Hawaii 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.
