Map of USGS gauge 05540130 and the river around it
Where WEST BRANCH DU PAGE RIVER NEAR NAPERVILLE, IL sits, with 2 other gauges on the same river and our water's map point.
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: 46–186 ft³/s (middle half of 38 years of record). Now: 102 ft³/s, normal.
Normal for this date. 102 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 38 years of record (1989–2026): 10th 36, 25th 46, median 76, 75th 186, 90th 375 ft³/s.
Daily means on record for Nov 5: lowest 24 ft³/s, highest 649 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).
Steady over 24 hours (−5.6% discharge). 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 the agency lists for West Branch DuPage River: Smallmouth Bass.
