Normal for Nov 5: 272–425 ft³/s (middle half of 24 years of record). Now: 391 ft³/s, normal.
Normal for this date. 391 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 24 years of record (2003–2026): 10th 83, 25th 272, median 335, 75th 425, 90th 460 ft³/s.
Daily means on record for Nov 5: lowest 54.2 ft³/s, highest 481 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 (+2.6% 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.

Where TRUCKEE R A BOCA BRIDGE NR TRUCKEE CA sits, with 7 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 CDFW uses are 67°F.
This gauge is on the same river as our page for Truckee River, but no agency page we read lists its species.
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.
