Active weather warnings for Ohio
# Ohio Storm Center Report
Ohio residents, particularly those in east central counties including Belmont, Carroll, Columbiana, Coshocton, Guernsey, Harrison, Jefferson, Monroe, Muskingum, Noble, and Tuscarawas, should prepare for significant flooding threats through Saturday morning. A Flood Watch remains in effect as additional thunderstorms are expected to produce heavy rainfall with rates of 1-2 inches per hour, creating dangerous flash flooding conditions in low-lying areas, poor drainage zones, and urban locations. Meanwhile, residents in Auglaize, Champaign, Logan, Mercer, and Shelby Counties face a Heat Advisory with heat index values reaching 100-105°F through 8 PM EDT today, increasing risks of heat-related illness. Stay weather-aware, avoid flooded roadways, remain hydrated during excessive heat, and monitor local emergency management for updates.

799 daily readings from 187 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 250%: 22 readings above that — including the 1112% peak in Aug 2026 — 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.

Flow report FAQ
About Ohio streamflow
What are river levels like in Ohio right now?
As of September 4, 2026, Ohio rivers are running at 90% of normal across 189 USGS streamgauges, and the Ohio River At Ironton is reporting the highest discharge at 12,300 cfs. The full sortable gauge table is below.
Which Ohio river is running highest right now?
As of September 4, 2026, the highest discharge in Ohio is 12,300 cfs on the Ohio River At Ironton. See the sortable gauge table for the full statewide ranking.
Are Ohio rivers high or low right now?
Compare the statewide percent-of-normal on this page: above 100% means Ohio 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 Ohio 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 Ohio 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 Ohio 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.
