Map of USGS gauge 05551675 and the river around it
Where BLACKBERRY CREEK NEAR MONTGOMERY, IL sits, with 1 other gauge 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.
Species list not on file for this gauge. Check the Illinois Department of Natural Resources: Illinois fish stocking · Illinois Fishing Information 2026 (regulations).
Normal for Nov 5: 13–37 ft³/s (middle half of 28 years of record). Now: 44.3 ft³/s, above normal.
Above normal for this date. 44.3 ft³/s is between the 75th and 90th percentiles of daily mean flow for Nov 5 at this gauge over 28 years of record (1999–2026): 10th 9.4, 25th 13, median 21, 75th 37, 90th 76 ft³/s.
Daily means on record for Nov 5: lowest 3.2 ft³/s, highest 115 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 (−9.2% 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.
Below NWS action stage. The National Weather Service reports this gauge below its action stage. That is not a statement that wading is safe.
Flood categories: action stage, minor, moderate and major flooding (National Weather Service)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.
