Map of USGS gauge 03343350 and the river around it
Where BLACK SLOUGH AT CR 500N NR PHILO, IL sits.
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).
USGS publishes no daily statistics for this gauge, so the reading is not compared with the record.
Falling over 24 hours: discharge down 17.6%, from 1.31 to 1.08 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.
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.
Turn Around Don't Drown (National Weather Service)Guidance from the readings above and the published thresholds named with each line; not a fishing forecast, a safety guarantee or a statement about access. Local rules and closures come first.
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.
