Map of USGS gauge 06076690 and the river around it
Where Smith River near Ft Logan MT sits, with 2 other gauges 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 Smith River: Brook Trout, Brown Trout, Burbot, Common Carp, Fathead Minnow, Flathead Chub, Longnose Dace, Longnose Sucker, Mottled Sculpin, Mountain Sucker, Mountain Whitefish, Rainbow Trout, Stonecat, Walleye, White Sucker, Yellow Perch.
Normal for Nov 5: 86–129 ft³/s (middle half of 32 years of record). Now: 125 ft³/s, normal.
Normal for this date. 125 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 32 years of record (1978–2026): 10th 63, 25th 86, median 105, 75th 129, 90th 158 ft³/s.
Daily means on record for Nov 5: lowest 32.2 ft³/s, highest 239 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 (−2.3% 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.
