About Rogue River at Grants Pass
This gauge measures Rogue River at Grants Pass, Oregon — the reading paddlers, anglers and outfitters on this stretch check before committing to a shuttle.
Hellgate; highest outfitter concentration in Oregon.
Raw CFS means little on its own, so every reading on this page is shown against the USGS median for the same calendar day — 1,570 CFS for late July, from 86 years of record.
Because the National Weather Service also operates a forecast point here, the page carries the official flood-category ladder and the NWS's own stage-by-stage impact statements.
Rogue River at Grants Pass — common questions
What is the current flow on Rogue River at Grants Pass?
As of the last reading on this page, Rogue River at Grants Pass was running 1,180 CFS at a gage height of 1.16 ft, or 75% of the USGS median for this date. The number updates automatically from USGS gauge 14361500, which reports every 15 to 60 minutes.
Is that high or low for this time of year?
The USGS median flow for late July at this gauge is 1,570 CFS, calculated from 86 years of record (1940–2026). Comparing today's reading against that median is the only way a raw CFS number tells you anything — 200 CFS is a drought on one river and a flood on another.
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 Rogue 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.
