Normal for Nov 5: 8.5–66 ft³/s (middle half of 111 years of record). Now: 18.2 ft³/s, normal.
Normal for this date. 18.2 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 111 years of record (1916–2026): 10th 4.6, 25th 8.5, median 18, 75th 66, 90th 121 ft³/s.
Daily means on record for Nov 5: lowest 2.15 ft³/s, highest 222 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 (−7.1% 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.
Water temperature, last 7 days: 169 readings from Oct 29, 6:30 PM PDT to Nov 5, 5:30 PM PST; ranging 43.5 to 48 °F; latest 43.9 °F.

Cold Water Hazards and Safety (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.
