Illinois River: water levels along the river

We have 18 gauges on the Illinois River. 1 is below normal for the date and 1 above. Low and high readings are fairly evenly spread.

The gauges on this page are spread across Oregon, Illinois, Arkansas and Oklahoma. Reading the gauges in order shows how a rise or a dry spell travels downstream, usually over a day or more on a big river. Fall is often a low point for rivers after the summer, until steady rain returns.
