Where Flathead River at Flathead British Columbia sits.
No current water-temperature reading at this gauge, so no temperature guidance is given. Take a stream thermometer. This gauge's state is not on file. The lines below are the National Park Service's, federal guidance: 68°F.

Normal for Nov 5: 208–438 ft³/s (middle half of 83 years of record). Now: 199 ft³/s, below normal.
Below normal for this date. 199 ft³/s is between the 10th and 25th percentiles of daily mean flow for Nov 5 at this gauge over 83 years of record (1933–2026): 10th 166, 25th 208, median 266, 75th 438, 90th 784 ft³/s.
Daily means on record for Nov 5: lowest 129 ft³/s, highest 1,370 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.
Below NWS action stage. The National Weather Service reports this gauge below its action stage. That is not a statement that wading is safe.
