Map of USGS gauge 05536890 and the river around it
Where CHICAGO SANITARY AND SHIP CANAL NR 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.
Normal for Nov 5: 1,320–3,140 ft³/s (middle half of 19 years of record). Now: 2,770 ft³/s, normal.
Normal for this date. 2,770 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 19 years of record (2008–2026): 10th 1,220, 25th 1,320, median 1,600, 75th 3,140, 90th 3,710 ft³/s.
Daily means on record for Nov 5: lowest 580 ft³/s, highest 3,780 ft³/s.
Classes as USGS labels them (hyswap: flow categories (WDFN_stats schema) (U.S. Geological Survey) ); percentiles from the USGS daily statistics (U.S. Geological Survey) (approved daily means; the reading is provisional and instantaneous).
Rising over 24 hours: discharge up 3,217.4%, from 83.5 to 2,770 ft³/s. 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).
