Map of USGS gauge 12372000 and the river around it
Where Flathead River near Polson MT sits, with 1 other gauge on the same river and our water's map point.
Under Montana FWP's 68°F line. Water 47.3°F now; the highest in the last 24 hours was 47.8°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)Normal for Nov 5: 5,250–10,300 ft³/s (middle half of 88 years of record). Now: 7,280 ft³/s, normal.
Normal for this date. 7,280 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 88 years of record (1939–2026): 10th 3,990, 25th 5,250, median 7,460, 75th 10,300, 90th 11,800 ft³/s.
Daily means on record for Nov 5: lowest 2,820 ft³/s, highest 20,400 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 (+1% 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 Flathead River, but no agency page we read lists its species.
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)Cold water. Water 47.3°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.
