Map of USGS gauge 06090300 and the river around it
Where Missouri River near Great Falls MT sits, with 2 other gauges on the same river.
No current water-temperature reading at this gauge, so no temperature guidance is given. Take a stream thermometer: the trout lines Montana FWP uses are 66°F, 68°F and 73°F.

Normal for Nov 5: 4,528–6,718 ft³/s (middle half of 70 years of record). Now: 4,450 ft³/s, below normal.
Below normal for this date. 4,450 ft³/s is between the 10th and 25th percentiles of daily mean flow for Nov 5 at this gauge over 70 years of record: 10th 4,005, 25th 4,528, median 5,520, 75th 6,718, 90th 7,695 ft³/s.
Daily means on record for Nov 5: lowest 3,610 ft³/s, highest 11,800 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 (+1.6% 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.
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.
