Map of USGS gauge 06038500 and the river around it
Where Madison River bl Hebgen Lake nr Grayling MT sits, with 2 other gauges on the same river and our water's map point.
Under Montana FWP's 68°F line. Water 47.8°F now; the highest in the last 24 hours was 48.4°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.”
Normal for Nov 5: 854–1,720 ft³/s (middle half of 88 years of record). Now: 641 ft³/s, much below normal.
Much below normal for this date. 641 ft³/s is below the 10th percentile of daily mean flow for Nov 5 at this gauge over 88 years of record (1939–2026): 10th 679, 25th 854, median 1,110, 75th 1,720, 90th 2,160 ft³/s.
Daily means on record for Nov 5: lowest 322 ft³/s, highest 3,760 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.

Cold water. Water 47.8°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.
