Active weather warnings for Wyoming
A Fire Weather Watch remains in effect across central and southwestern Wyoming through October 9 at 7:00 PM MDT, issued by the National Weather Service in Riverton. Fremont, Natrona, Johnson, and Sweetwater counties face critical fire conditions with extremely low humidity levels between 10-15%, unseasonably warm temperatures reaching the upper 70s to mid-80s, and strong southwest winds gusting 35-40 mph. These combined factors could produce erratic and dangerous fire behavior. Residents in affected areas including Casper, Riverton, Buffalo, and Rock Springs should remain vigilant, monitor local conditions closely, and be prepared to evacuate if necessary. Avoid outdoor burning and report any fires immediately to local authorities.
How Wyoming’s rivers compare to normal
Every gauge placed by its own percent of normal, and three years of the statewide trend.
Where every gauge actually sits
One dot per Wyoming streamgauge, placed by its own percent of normal. The state average is a single line through all of it.
Percent of normal compares today's discharge with the historical average for this calendar day. Tap any dot to open that gauge.
Wyoming streamflow, three water years
Statewide percent of normal, every day since Oct 2023. The dotted line is normal.
799 daily readings from 76 reporting gauges. Percent of normal is today's statewide discharge against the historical average for the same calendar day — 100% is normal, not "good". The line breaks in 2 places where the record skips more than five days — those are gaps in reporting, not readings of zero.

About Wyoming streamflow
What are river levels like in Wyoming right now?
As of October 8, 2026, Wyoming rivers are running at 68% of normal across 76 USGS streamgauges, and the Snake River Ab Reservoir Nr Alpine Wy is reporting the highest discharge at 1,630 cfs. The full sortable gauge table is below.
Which Wyoming river is running highest right now?
As of October 8, 2026, the highest discharge in Wyoming is 1,630 cfs on the Snake River Ab Reservoir Nr Alpine Wy. See the sortable gauge table for the full statewide ranking.
Are Wyoming rivers high or low right now?
Compare the statewide percent-of-normal on this page: above 100% means Wyoming rivers are running higher than the seasonal average for the date, below 100% means lower (a dry spell or drought). Each gauge also shows its own percent of median.
Where does the Wyoming streamflow data come from?
The U.S. Geological Survey National Water Information System. USGS streamgauges report continuously (every 15 minutes) and the data is the canonical real-time record for U.S. rivers. Snoflo pulls the latest readings and joins them to a 7-day NOAA weather forecast for each station.
What is cfs?
Cubic feet per second — the standard unit for streamflow. One cfs is about 7.5 gallons per second. Small creeks run at single-digit cfs; the Mississippi at hundreds of thousands.
What does Gauge Height mean?
The water level at the gauge in feet above the reference datum. Used together with discharge to track river state. Flood stage and runnable levels are typically expressed in gauge height (e.g., "flood at 16 ft").
How fresh is the Wyoming data?
USGS streamgauges report every 15 minutes; Snoflo re-pulls throughout the day. The AI briefing regenerates daily.
Can I get a flow alert for a Wyoming gauge?
Yes. Save any USGS gauge as a favorite in the Snoflo iOS app, set a discharge or stage threshold (e.g. "alert me when discharge crosses 2,000 cfs"), and you'll get a push the moment it crosses.
Is this a substitute for an NWS flood warning?
No. Snoflo is informational. For flood life-safety decisions always follow guidance from your local NWS forecast office and state emergency management. Snoflo data is one input among several.
