Map of USGS gauge 06052500 and the river around it
Where Gallatin River at Logan MT sits, with 1 other gauge on the same river and our water's map point.
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.
Species the agency lists for Gallatin River: Brook Trout, Brown Trout, Longnose Dace, Longnose Sucker, Mottled Sculpin, Mountain Sucker, Mountain Whitefish, Rainbow Trout, Westslope Cutthroat Trout, White Sucker, Yellowstone Cutthroat Trout.
Normal for Nov 5: 697–924 ft³/s (middle half of 111 years of record). Now: 784 ft³/s, normal.
Normal for this date. 784 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 111 years of record (1894–2026): 10th 567, 25th 697, median 813, 75th 924, 90th 1,070 ft³/s.
Daily means on record for Nov 5: lowest 325 ft³/s, highest 1,320 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 (−1.8% 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.
