Delaware River at Delaware Water Gap — common questions

What is the current flow on Delaware River at Delaware Water Gap?

As of the last reading on this page, Delaware River at Delaware Water Gap was running 5,630 CFS at a gage height of 6.03 ft. The number updates automatically from USGS gauge 01440200, which reports every 15 to 60 minutes.

Is that high or low for this time of year?

USGS has not published enough daily statistics for this site to compute a seasonal median, so this page shows the live reading and its recent trend rather than a percent-of-normal figure.

How often does this reading update?

USGS transmits from this gauge every 15 to 60 minutes. This page bakes in the most recent reading when it is rebuilt, then refreshes live from USGS when you open it. Readings are provisional and subject to revision by USGS.

What flow is good for tubing Delaware River?

riverlvl does not publish a recommended tubing range — that call belongs to the outfitters and the local authorities who know this stretch. What this page gives you is the objective input: today's flow, the seasonal median for the same date, and where the reading sits in the 12-month record. Local outfitters generally publish their own cutoffs, and they close when the river is up.

Does rain upstream change this reading quickly?

Yes. This is a free-flowing gauge, so it responds directly to rain in the basin upstream. Flashy rises of several feet in a few hours are normal on rivers like this after a heavy storm, which is why the reading is worth checking the morning you go.

What does gage height mean versus CFS?

Gage height is how high the water surface is above the gauge's own zero point, in feet — a local measure, not depth and not elevation. CFS is cubic feet per second, the volume of water moving past the gauge. Flood stages are set in gage height; float and paddling conditions are usually discussed in CFS.
