Is the Mississippi River flooding?
The Mississippi River is tracked by 4 USGS streamgauges in Illinois. This page compares each gauge’s live water level against its official National Weather Service flood stage, refreshed every 15 minutes, so you can tell whether the Mississippi River is running normal, rising toward flood stage, or already flooding. Right now, every gauge on the Mississippi River is below flood stage. Gauges without a published flood stage show water level and flow only. For nearby rivers, see all Illinois river levels.
