Map of USGS gauge 11179100 and the river around it
Where ALAMEDA C NR FREMONT CA sits, with 7 other gauges on the same river.
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.
Normal for Nov 5: 1.5–9.1 ft³/s (middle half of 12 years of record). Now: 11.6 ft³/s, above normal.
Above normal for this date. 11.6 ft³/s is between the 75th and 90th percentiles of daily mean flow for Nov 5 at this gauge over 12 years of record (2014–2025): 10th 0.23, 25th 1.5, median 5.1, 75th 9.1, 90th 17 ft³/s.
Daily means on record for Nov 5: lowest 0 ft³/s, highest 17.7 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 (+5.5% 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.

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.
