Map of USGS gauge 13050500 and the river around it
Where HENRYS FORK AT ST ANTHONY ID 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 Idaho Fish and Game uses are 66°F and 73°F.
Species the agency lists for : Brown Trout, Cutthroat Trout, Brook Trout, Mountain Whitefish, Rainbow Trout, Cutbow - Cutthroat x Rainbow Trout.
Normal for Nov 5: 1,260–1,790 ft³/s (middle half of 72 years of record). Now: 1,170 ft³/s, below normal.
Below normal for this date. 1,170 ft³/s is between the 10th and 25th percentiles of daily mean flow for Nov 5 at this gauge over 72 years of record (1920–2026): 10th 1,140, 25th 1,260, median 1,490, 75th 1,790, 90th 2,100 ft³/s.
Daily means on record for Nov 5: lowest 630 ft³/s, highest 2,710 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 (−1.7% 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.

Below NWS action stage. The National Weather Service reports this gauge below its action stage. That is not a statement that wading is safe.
Flood categories: action stage, minor, moderate and major flooding (National Weather Service)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.

NWS observed 3.46 ft stage, 1,170 ft³/s at Nov 5, 4:45 PM MST (NWS gauge ANTI1; its stage datum can differ from the USGS gauge height).
NWS river forecast forecast issued Nov 5, 8:13 AM MST. Highest point: 3.48 ft, 1,200 ft³/s on Nov 6, 11:00 AM MST (Below NWS action stage).
