USGS keeps no flow statistics at this gauge, so there is no normal range for flow; the chart shows gauge height as USGS publishes it.
Map of USGS gauge 05536900 and the river around it
Where CHICAGO SANITARY AND SHIP CANAL AT LEMONT, IL sits, with 3 other gauges on the same river.
No current water-temperature reading at this gauge, so no temperature guidance is given. Take a stream thermometer. Illinois DNR publishes no water-temperature line for trout anglers that we found. The lines below are the National Park Service's, federal guidance, not a Illinois rule: 68°F.
Falling over 24 hours: gauge height down 0.25 ft. Rising or falling means a change of more than 10% in discharge (or 0.2 ft of gauge height) over 24 hours; our rule of thumb, not a USGS class.
Species list not on file for this gauge. Check the Illinois Department of Natural Resources: Illinois fish stocking · Illinois Fishing Information 2026 (regulations).
Turn Around Don't Drown. “A mere 6 inches of fast-moving flood water can knock over an adult.” No flow number makes a crossing safe; if in doubt, stay out.

The National Weather Service has no flood-stage gauge here, so no official flood category is shown.
Checked Nov 5, 7:16 PM CST; readings refresh at most every 15 minutes and statistics daily. Provisional USGS data can be revised. Conditions change: re-check before you go. This is general guidance, not a fishing forecast, a safety guarantee or a statement about access.
