Map of USGS gauge 13068495 and the river around it
Where BLACKFOOT RIVER BYPASS NR BLACKFOOT ID sits, with 4 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 Idaho Fish and Game uses are 66°F and 73°F.
Normal for Nov 5: 12–129 ft³/s (middle half of 62 years of record). Now: 46.6 ft³/s, normal.
Normal for this date. 46.6 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 62 years of record (1965–2026): 10th 1.3, 25th 12, median 43, 75th 129, 90th 265 ft³/s.
Daily means on record for Nov 5: lowest 0 ft³/s, highest 683 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).
Falling over 24 hours: discharge down 29.5%, from 66.1 to 46.6 ft³/s. 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.
Species the agency lists for Blackfoot River: Cutthroat Trout, Mountain Whitefish, Rainbow Trout.

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, 7:06 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.
