Where Big Muddy Creek nr mouth nr Culbertson MT sits.
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: 0.99–12 ft³/s (middle half of 25 years of record). Now: 11.4 ft³/s, normal.
Normal for this date. 11.4 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 25 years of record (1982–2026): 10th 0.05, 25th 0.99, median 5.4, 75th 12, 90th 28 ft³/s.
Daily means on record for Nov 5: lowest 0 ft³/s, highest 108 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 (+8.6% 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.
