About Guadalupe River at Kerrville
This is the reference gauge for Guadalupe River at Kerrville, Texas. It is the reading local emergency managers, the National Weather Service and residents watch when the river comes up.
County-seat flood gauge; Louise Hays Park.
Raw CFS means little on its own, so every reading on this page is shown against the USGS median for the same calendar day — 43 CFS for late July, from 40 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.

As of the last reading on this page, Guadalupe River at Kerrville was running 401 CFS at a gage height of 1.88 ft, or 933% of the USGS median for this date. The number updates automatically from USGS gauge 08166200, 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 43 CFS, calculated from 40 years of record (1986–2026). 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.

What happens at each flood stage here?
The National Weather Service publishes 10 stage-by-stage impact statements for this gauge, describing what specific roads, properties and structures are affected at each level. They are reproduced verbatim on this page, lowest to highest. They are NWS descriptions, not riverlvl's.
