About Colorado River at Kremmling
This gauge measures Colorado River at Kremmling, Colorado — the reading paddlers, anglers and outfitters on this stretch check before committing to a shuttle.
Pumphouse to Radium and Gore Canyon.
Raw CFS means little on its own, so every reading on this page is shown against the USGS median for the same calendar day — 1,020 CFS for late July, from 63 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.
Colorado River at Kremmling — common questions
What is the current flow on Colorado River at Kremmling?
As of the last reading on this page, Colorado River at Kremmling was running 936 CFS at a gage height of 5.38 ft, or 92% of the USGS median for this date. The number updates automatically from USGS gauge 09058000, 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 1,020 CFS, calculated from 63 years of record (1962–2026). 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 is a runnable level on this stretch?
riverlvl deliberately does not publish a runnable range. American Whitewater and the local paddling community maintain the correlations for this reach, and they are the authority. This page gives you the raw inputs — current CFS, gage height, the seasonal median, and the 12-month hydrograph — so you can apply whatever range you trust.
How fast can this gauge come up?
This is a free-flowing gauge, so it rises with rain in the basin. The 12-month chart on this page shows the shape of the past year's rises, which is the best available guide to how flashy this particular reach is.
Where does this data come from?
The flow and gage height come from USGS gauge 09058000, public-domain data from the U.S. Geological Survey. The flood categories, impact statements and forecast come from the National Weather Service's National Water Prediction Service, gauge KRMC2.
