Map of USGS gauge 06185500 and the river around it
Where Missouri River near Culbertson MT sits, with 4 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: 5,250–11,100 ft³/s (middle half of 67 years of record). Now: 7,600 ft³/s, normal.
Normal for this date. 7,600 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 67 years of record (1959–2025): 10th 4,170, 25th 5,250, median 6,750, 75th 11,100, 90th 14,100 ft³/s.
Daily means on record for Nov 5: lowest 3,450 ft³/s, highest 22,100 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 (−2.2% 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.
