Map of USGS gauge 12362500 and the river around it
Where S F Flathead River nr Columbia Falls MT sits and our water's map point.
Under Montana FWP's 68°F line. Water 43.5°F now; the highest in the last 24 hours was 43.7°F. Montana FWP cites a study in which trout “caught and released from water with a temperature above 68 degrees F were far more likely to perish than those taken from cooler water.” Water warms through the day: “Fish in the cool morning hours.”
“Giving a hoot”, Montana Outdoors (July–August 2024) (Montana Fish, Wildlife & Parks)Normal for Nov 5: 737–2,580 ft³/s (middle half of 102 years of record). Now: 2,660 ft³/s, above normal.
Above normal for this date. 2,660 ft³/s is between the 75th and 90th percentiles of daily mean flow for Nov 5 at this gauge over 102 years of record (1912–2025): 10th 408, 25th 737, median 1,790, 75th 2,580, 90th 7,040 ft³/s.
Daily means on record for Nov 5: lowest 157 ft³/s, highest 10,500 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 (+0.4% 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.
This gauge is on our page for South Fork Flathead River, but no agency page we read lists its species.
Cold water. Water 43.5°F. NWS: “Cold shock can be just as severe and dangerous from water temperatures of 50-60°F (10-15°C) as it is from water at 35°F (2°C).” “Always wear a life jacket in and around the water.”
Cold Water Hazards and Safety (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.

NWS observed 5.89 ft stage, 2,660 ft³/s at Nov 5, 7:45 PM MST (NWS gauge SFCM8; its stage datum can differ from the USGS gauge height).
