What makes the flow change on Sipsey Fork at Grayson?
Rain upstream, plus seasonal baseflow. The 12-month chart shows how it behaves through the year.
Is Sipsey Fork at Grayson high or low for this time of year?
The USGS median flow for late September here is 9.0 CFS, from 59 years of record (1967–2026). Today sits inside the middle half of those years, at 84% 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 02450250 every 15 to 60 minutes, and the National Weather Service reissues the flood forecast for GRAA1 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.
