Map of USGS gauge 05551700 and the river around it
Where BLACKBERRY CREEK NEAR YORKVILLE, 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: 16–52 ft³/s (middle half of 66 years of record). Now: 54.5 ft³/s, above normal.
Above normal for this date. 54.5 ft³/s is between the 75th and 90th percentiles of daily mean flow for Nov 5 at this gauge over 66 years of record (1961–2026): 10th 9.4, 25th 16, median 26, 75th 52, 90th 96 ft³/s.
Daily means on record for Nov 5: lowest 3.1 ft³/s, highest 139 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 (−3.7% 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.
