Where ALAMO CN NR PLEASANTON CA sits.
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: 2.4–3.6 ft³/s (middle half of 15 years of record). Now: 2.82 ft³/s, normal.
Normal for this date. 2.82 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 15 years of record (1980–2025): 10th 1.7, 25th 2.4, median 2.8, 75th 3.6, 90th 4.3 ft³/s.
Daily means on record for Nov 5: lowest 1.6 ft³/s, highest 4.46 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 (−7.8% 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.
