Delaware River Level & Flow

The latest reading on the Delaware River at Trenton, NJ — from the USGS streamgage, reporting gage height (feet) and streamflow (cubic feet per second). A major free-flowing eastern river supplying water to New York City and Philadelphia.The figure below is live, shown with the time it was taken, and framed as a measurement of flow — never a flood verdict.

What this reading means

Gage height is how high the water stands at the gage, in feet; streamflow is how much water is moving past, in cubic feet per second. Both rise and fall with rain, snowmelt and upstream dams. A high number here means the Delaware River is running full — but whether that is flooding depends on this river’s own banks and its official flood stage, which this page does not assert. It shows the measurement and its context, not a safe/unsafe verdict.
