Where Fisher River near Libby MT sits.
No current water-temperature reading at this gauge, so no temperature guidance is given. Take a stream thermometer: the trout lines Montana FWP uses are 66°F, 68°F and 73°F.

Normal for Nov 5: 114–195 ft³/s (middle half of 58 years of record). Now: 76 ft³/s, lowest for this date on record.
Lowest for this date on record for this date. 76 ft³/s is below the lowest daily mean recorded on this date of daily mean flow for Nov 5 at this gauge over 58 years of record (1968–2025): 10th 100, 25th 114, median 146, 75th 195, 90th 282 ft³/s.
Daily means on record for Nov 5: lowest 85 ft³/s, highest 2,110 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 (+0% 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.
