Map of USGS gauge 11251000 and the river around it
Where SAN JOAQUIN R BL FRIANT CA sits and our water's map point.
Under CDFW's 67°F line. Water 58.8°F now; the highest in the last 24 hours was 60.3°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.
CDFW Recommends “Hoot Owl” Practices for Fishing Inland Waters During Drought (15 July 2022)Normal for Nov 5: 87–408 ft³/s (middle half of 86 years of record). Now: 428 ft³/s, above normal.
Above normal for this date. 428 ft³/s is between the 75th and 90th percentiles of daily mean flow for Nov 5 at this gauge over 86 years of record (1941–2026): 10th 62, 25th 87, median 139, 75th 408, 90th 682 ft³/s.
Daily means on record for Nov 5: lowest 26 ft³/s, highest 1,430 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 (+4.4% 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.
Species the agency lists for San Joaquin River: Steelhead.
Source: Steelhead Report and Restoration Card location codes (named river systems) (California Department of Fish and Wildlife Fisheries Branch).
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.
Turn Around Don't Drown (National Weather Service)Specific conductance 33 µS/cm at Nov 5, 7:30 PM PST; 7-day range 31–34 µS/cm
Dissolved ions: Specific conductance rises with the ions dissolved in the water. No fishing threshold is published for it; compare with this gauge's own recent readings.
Conductivity (Electrical Conductance) and Water (U.S. Geological Survey)Guidance from the readings above and the published thresholds named with each line; not a fishing forecast, a safety guarantee or a statement about access. Local rules and closures come first.
The National Weather Service has no flood-stage gauge here, so no official flood category is shown.
Checked Nov 5, 8:28 PM PST; readings refresh at most every 15 minutes and statistics daily. Provisional USGS data can be revised. Conditions change: re-check before you go. This is general guidance, not a fishing forecast, a safety guarantee or a statement about access.
