Map of USGS gauge 06043120 and the river around it
Where Gallatin River above Deer Creek, near Big Sky, 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.
USGS publishes no daily statistics for this gauge, so the reading is not compared with the record.
Steady over 24 hours (+0% 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.
From our page for Gallatin River, on the same river as this gauge; the agency list is for the water, not this exact reach. Source: FISHMT :: Waterbody Details (Montana Fish, Wildlife & Parks).
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.
