Map of USGS gauge 12335100 and the river around it
Where Blackfoot R ab Nevada Cr nr Helmville MT sits 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 Blackfoot River: Brook Trout, Brown Trout, Bull Trout, Largescale Sucker, Longnose Dace, Longnose Sucker, Mottled Sculpin, Mountain Whitefish, Northern Pike, Northern Pike Minnow, Peamouth, Rainbow Trout, Redside Shiner, Rocky Mountain Sculpin, Slimy Sculpin, Westslope Cutthroat Trout, Yellow Perch.

Normal for Nov 5: 148–178 ft³/s (middle half of 25 years of record). Now: 192 ft³/s, above normal.
Above normal for this date. 192 ft³/s is between the 75th and 90th percentiles of daily mean flow for Nov 5 at this gauge over 25 years of record (2000–2026): 10th 138, 25th 148, median 169, 75th 178, 90th 204 ft³/s.
Daily means on record for Nov 5: lowest 127 ft³/s, highest 245 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 (−1.5% 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.
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.
Turn Around Don't Drown (National Weather Service)Guidance from the readings above and the published thresholds named with each line; not a fishing forecast, a safety guarantee or a statement about access. Local rules and closures come first.
The National Weather Service has no flood-stage gauge here, so no official flood category is shown.
Checked Nov 5, 8:20 PM MST; readings refresh at most every 15 minutes and statistics daily. Provisional USGS data can be revised. Conditions change: re-check before you go. This is general guidance, not a fishing forecast, a safety guarantee or a statement about access.
