About U.S. river levels
How are U.S. rivers running right now?
As of November 11, 2026, 6,500 USGS streamgauges are reporting; the typical gauge is at 80% of normal for the date, with 1,833 above normal and 3,644 below. The state map above shows where rivers are high or low.
What does “percent of normal” mean?
Today’s flow at a gauge compared with its historical average for the same calendar day. 100% is normal. Well above 150% on a small or medium river often means high water; below 50% points to drought-stressed flow.
What is cfs?
Cubic feet per second, the standard unit for river flow. One cfs is about 7.5 gallons passing the gauge every second. Small creeks run in single digits; the lower Mississippi runs in the hundreds of thousands.
How fresh is the data?
USGS gauges report every 15 minutes to an hour and Snoflo refreshes its tables through the day. Gauges that have been silent for more than three days are left out of today’s numbers.
Where does the data come from?
Discharge and gage height are from the USGS National Water Information System; flood stages from the National Weather Service.
Can I get an alert when my river rises?
Yes — favorite any gauge in the Snoflo app and set a flow or stage threshold.
Is this a substitute for official flood warnings?
No. Snoflo is informational. For life-safety decisions follow your local NWS forecast office and emergency management.
