Map of USGS gauge 12392155 and the river around it
Where LIGHTNING CREEK AT CLARK FORK ID sits.
No current water-temperature reading at this gauge, so no temperature guidance is given. Take a stream thermometer: the trout lines Idaho Fish and Game uses are 66°F and 73°F.

Normal for Nov 5: 49–446 ft³/s (middle half of 37 years of record). Now: 10 ft³/s, much below normal.
Much below normal for this date. 10 ft³/s is below the 10th percentile of daily mean flow for Nov 5 at this gauge over 37 years of record (1989–2026): 10th 26, 25th 49, median 119, 75th 446, 90th 820 ft³/s.
Daily means on record for Nov 5: lowest 3.42 ft³/s, highest 1,210 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 (−5.7% 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.
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.
