Chicago Sanitary and Ship Canal: water levels along the river

3 gauges report along the Chicago Sanitary and Ship Canal. 1 is below normal for the date and 2 above. Low and high readings are fairly evenly spread.

The gauges are in Illinois. 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.
