Map of USGS gauge 11467510 and the river around it
Where SF GUALALA R NR THE SEA RANCH 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.
Species list not on file for this gauge. Check the California Department of Fish and Wildlife: California fish planting schedule · California fishing regulations.
Normal for Nov 5: 4.1–15 ft³/s (middle half of 20 years of record). Now: 1.97 ft³/s, below normal.
Below normal for this date. 1.97 ft³/s is between the 10th and 25th percentiles of daily mean flow for Nov 5 at this gauge over 20 years of record (1992–2026): 10th 0.85, 25th 4.1, median 6, 75th 15, 90th 109 ft³/s.
Daily means on record for Nov 5: lowest 0.18 ft³/s, highest 240 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 (−7.9% 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.
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.
