Active weather warnings for Idaho
# Idaho Natural Disaster Report
A Red Flag Warning is in effect for the Sawtooth Range and Northern Sawtooth National Forest (Fire Weather Zone 422) in central Idaho until 3:00 PM MDT on September 2nd. Scattered thunderstorms are expected to develop as early as 6:00 AM, with dangerous lightning creating extreme fire danger across the region. Outflow winds gusting to 45 mph will further elevate fire weather conditions and increase initial attack burdens for wildland firefighting resources. Residents and visitors in areas near Stanley, Ketchum, and surrounding mountain communities should exercise extreme caution, avoid outdoor burning, and be prepared for rapidly developing fire conditions. Thunderstorms are expected to move northward into the Salmon-Challis National Forest by mid-afternoon.

799 daily readings from 161 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 axis tops out at 160%: 8 readings above that — including the 187% peak in Dec 2025 — are drawn along the top edge, so a few flood days cannot flatten three years of everything else. The line breaks in 2 places where the record skips more than five days — those are gaps in reporting, not readings of zero.

About Idaho streamflow
What are river levels like in Idaho right now?
As of September 2, 2026, Idaho rivers are running at 97% of normal across 168 USGS streamgauges, and the Snake River Bl Mcduff Rapids At China Gardens is reporting the highest discharge at 13,600 cfs. The full sortable gauge table is below.
Which Idaho river is running highest right now?
As of September 2, 2026, the highest discharge in Idaho is 13,600 cfs on the Snake River Bl Mcduff Rapids At China Gardens. See the sortable gauge table for the full statewide ranking.
Are Idaho rivers high or low right now?
Compare the statewide percent-of-normal on this page: above 100% means Idaho 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 Idaho 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 Idaho 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 Idaho 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.
