Illinois river levels: common questions
Is any river flooding in Illinois right now?
No gauge in the state is above flood stage. No gauge is above action stage either.
Which rivers are gauged in Illinois?
17 in total, listed above. The most heavily instrumented is the Mississippi River, with 120 gauges. A river appears under every state it runs through, so a page reached from here may cover reaches outside Illinois as well.
What is the difference between flood stage and action stage?
Action stage is the level at which the Weather Service starts paying attention and agencies begin preparing. Flood stage is the level at which water starts affecting property or roads at that specific location. Both are set per gauge by the local Weather Service office, which is why two gauges on the same river can have very different numbers.
