Map of USGS gauge 12340000 and the river around it
Where Blackfoot River near Bonner MT sits and our water's map point.
Under Montana FWP's 68°F line. Water 39.9°F now; the highest in the last 24 hours was 39.9°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: 540–724 ft³/s (middle half of 92 years of record). Now: 641 ft³/s, normal.
Normal for this date. 641 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 92 years of record (1899–2026): 10th 467, 25th 540, median 624, 75th 724, 90th 897 ft³/s.
Daily means on record for Nov 5: lowest 361 ft³/s, highest 1,560 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 (−1.1% 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.
Species the agency lists for Blackfoot River: Brook Trout, Brown Trout, Bull Trout, Largescale Sucker, Longnose Dace, Longnose Sucker, Mottled Sculpin, Mountain Whitefish, Northern Pike, Northern Pike Minnow, Peamouth, Rainbow Trout, Redside Shiner, Rocky Mountain Sculpin, Slimy Sculpin, Westslope Cutthroat Trout, Yellow Perch.

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 39.9°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.
