Normal for Nov 5: 6,040–10,900 ft³/s (middle half of 43 years of record). Now: 7,580 ft³/s, normal.
Normal for this date. 7,580 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 43 years of record (1984–2026): 10th 4,790, 25th 6,040, median 9,120, 75th 10,900, 90th 12,600 ft³/s.
Daily means on record for Nov 5: lowest 4,020 ft³/s, highest 19,700 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 (+0.5% 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.
Water temperature, last 7 days: 169 readings from Oct 29, 7:30 PM MDT to Nov 5, 6:30 PM MST; ranging 46.4 to 52 °F; latest 47.1 °F.
USGS provisional data may be revised. Source: USGS instantaneous values.

Map of USGS gauge 12388700 and the river around it
Where Flathead River at Perma MT sits, with 1 other gauge on the same river and our water's map point.
Under Montana FWP's 68°F line. Water 47.1°F now; the highest in the last 24 hours was 47.3°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.”

Cold water. Water 47.1°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.
