Map of USGS gauge 06054500 and the river around it
Where Missouri River at Toston MT sits.
Under Montana FWP's 68°F line. Water 41.4°F now; the highest in the last 24 hours was 42.1°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: 3,920–5,130 ft³/s (middle half of 92 years of record). Now: 3,950 ft³/s, normal.
Normal for this date. 3,950 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 92 years of record (1891–2025): 10th 3,410, 25th 3,920, median 4,540, 75th 5,130, 90th 6,100 ft³/s.
Daily means on record for Nov 5: lowest 2,550 ft³/s, highest 7,590 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 (−2.9% 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.

Flood categories: action stage, minor, moderate and major flooding (National Weather Service)Cold water. Water 41.4°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.
