Map of USGS gauge 11525500 and the river around it
Where TRINITY R A LEWISTON CA sits, with 3 other gauges on the same river and our water's map point.
Normal for Nov 5: 270–312 ft³/s (middle half of 65 years of record). Now: 315 ft³/s, above normal.
Above normal for this date. 315 ft³/s is between the 75th and 90th percentiles of daily mean flow for Nov 5 at this gauge over 65 years of record (1962–2026): 10th 251, 25th 270, median 301, 75th 312, 90th 328 ft³/s.
Daily means on record for Nov 5: lowest 225 ft³/s, highest 381 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 (+0% 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.
Under CDFW's 67°F line. Water 48.6°F now; the highest in the last 24 hours was 48.9°F. That is not over the 67°F CDFW uses for its voluntary “Hoot Owl” watchlist: “Sustained afternoon water temperatures exceeding 67 degrees Fahrenheit for trout fisheries could trigger additions to the list.” Water warms in the afternoon; check again later in the day.

Cold water. Water 48.6°F. NWS: “Cold shock can be just as severe and dangerous from water temperatures of 50-60°F (10-15°C) as it is from water at 35°F (2°C).” “Always wear a life jacket in and around the water.”
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.
