Map of USGS gauge 12355500 and the river around it
Where N F Flathead River nr Columbia Falls MT sits and our water's map point.
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.
This gauge is on our page for North Fork Flathead River, but no agency page we read lists its species.
Normal for Nov 5: 767–1,380 ft³/s (middle half of 87 years of record). Now: 650 ft³/s, much below normal.
Much below normal for this date. 650 ft³/s is below the 10th percentile of daily mean flow for Nov 5 at this gauge over 87 years of record (1940–2026): 10th 658, 25th 767, median 988, 75th 1,380, 90th 2,300 ft³/s.
Daily means on record for Nov 5: lowest 497 ft³/s, highest 6,690 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 (−0.8% 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.
