State-wide streamflow overview
The Wisconsin flow picture in four data points -- where the state sits versus historical norms, what's flowing hardest, and what's spiking fastest.
Percent of normal
100% is the historical norm. Below 70% indicates drought; above 130% can flag elevated flood risk.

Where every gauge actually sits
One dot per Wisconsin 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.
Wisconsin streamflow, three water years
Statewide percent of normal, every day since Aug 2023. The dotted line is normal.
799 daily readings from 124 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%: 6 readings above that — including the 173% peak in Jun 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 Wisconsin streamflow
What are river levels like in Wisconsin right now?
As of September 4, 2026, Wisconsin rivers are running at 58% of normal across 124 USGS streamgauges, and the Mississippi River At Prescott is reporting the highest discharge at 6,230 cfs. The full sortable gauge table is below.
Which Wisconsin river is running highest right now?
As of September 4, 2026, the highest discharge in Wisconsin is 6,230 cfs on the Mississippi River At Prescott. See the sortable gauge table for the full statewide ranking.
Are Wisconsin rivers high or low right now?
Compare the statewide percent-of-normal on this page: above 100% means Wisconsin 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 Wisconsin 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 Wisconsin 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 Wisconsin 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.
