Map of USGS gauge 11173575 and the river around it
Where ALAMEDA C BL WELCH C NR SUNOL CA sits, with 7 other gauges on the same river.
Normal for Nov 5: 0.43–4.8 ft³/s (middle half of 27 years of record). Now: 6.8 ft³/s, much above normal.
Much above normal for this date. 6.8 ft³/s is above the 90th percentile of daily mean flow for Nov 5 at this gauge over 27 years of record (2000–2026): 10th 0.33, 25th 0.43, median 0.81, 75th 4.8, 90th 6 ft³/s.
Daily means on record for Nov 5: lowest 0.04 ft³/s, highest 9.95 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 (+4.9% 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 58.8°F now; the highest in the last 24 hours was 59.5°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.

Flow far above normal. Above the 90th percentile of daily mean flow for this date (USGS class “much above normal”), from 27 years of record. Expect higher, faster water than usual for the season.
hyswap: flow categories (WDFN_stats schema) (U.S. Geological Survey) Statistics documentation (percentiles of daily mean discharge) (U.S. Geological Survey)Cold water. Water 58.8°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.
