Map of USGS gauge 12354500 and the river around it
Where Clark Fork at St. Regis MT sits, with 3 other gauges on the same river.
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 list not on file for this gauge.
Normal for Nov 5: 2,920–4,000 ft³/s (middle half of 97 years of record). Now: 3,190 ft³/s, normal.
Normal for this date. 3,190 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 97 years of record (1930–2026): 10th 2,430, 25th 2,920, median 3,360, 75th 4,000, 90th 4,900 ft³/s.
Daily means on record for Nov 5: lowest 1,800 ft³/s, highest 10,200 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 (−2.1% 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.
Below NWS action stage. The National Weather Service reports this gauge below its action stage. That is not a statement that wading is safe.
NWS observed 5.62 ft stage, 3,190 ft³/s at Nov 5, 4:45 PM MST (NWS gauge SRGM8; its stage datum can differ from the USGS gauge height).
NWS river forecast forecast issued Nov 5, 7:53 AM MST. Highest point: 5.62 ft, 3,190 ft³/s on Nov 5, 11:00 AM MST (Below NWS action stage).
