Guadalupe River at Spring Branch — common questions
3 questions
Does rain upstream change Guadalupe River at Spring Branch quickly?
Yes. It is free-flowing, so rain upstream moves it directly. Several feet in a few hours is normal after a heavy storm.
Is Guadalupe River at Spring Branch high or low for this time of year?
The USGS median flow for late September here is 104 CFS, from 104 years of record (1922–2026). Today sits inside the middle half of those years, at 85% of the median. The comparison is what makes the raw number mean anything: the same reading is a drought on one river and a flood on another.
How often does this reading update?
USGS transmits from gauge 08167500 every 15 to 60 minutes, and the National Weather Service reissues the flood forecast for SRGT2 a few times a day — more often when the river is rising. This page refreshes from both when you open it. The timestamp is in the gauge's local time.
