Planning with Delaware river conditions

Browse USGS monitoring stations across Delaware 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.
