Map of USGS gauge 11273400 and the river around it
Where SAN JOAQUIN R AB MERCED R NR NEWMAN CA sits, with 4 other gauges on the same river and our water's map point.
Normal for Nov 5: 123–363 ft³/s (middle half of 17 years of record). Now: 311 ft³/s, normal.
Normal for this date. 311 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 17 years of record (2010–2026): 10th 50, 25th 123, median 253, 75th 363, 90th 442 ft³/s.
Daily means on record for Nov 5: lowest 41.3 ft³/s, highest 518 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 (−3.7% 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 60.3°F now; the highest in the last 24 hours was 61°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) (California Department of Fish and Wildlife)Species the agency lists for San Joaquin River: Steelhead.

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)Dissolved oxygen 7.1 mg/L at Nov 5, 7:30 PM PST; 7-day range 6.1–7.3 mg/L
Enough oxygen for coldwater fish: 7.1 mg/L meets the 6.5 mg/L EPA sets for coldwater fish (other life stages; eggs and fry need a 8 mg/L minimum).
Quality Criteria for Water 1986 (“Gold Book”): dissolved oxygen, Table 1; pH (U.S. Environmental Protection Agency)pH 7.7 at Nov 5, 7:30 PM PST; 7-day range 7.6–7.7
Within EPA's freshwater range: pH 7.7 is within the 6.5–9 range EPA gives for freshwater aquatic life.
Quality Criteria for Water 1986 (“Gold Book”): dissolved oxygen, Table 1; pH (U.S. Environmental Protection Agency)Turbidity 17.1 FNU at Nov 5, 7:30 PM PST; 7-day range 13.8–36.8 FNU
Water clarity: Turbidity measures the relative clarity of water: higher means murkier. No agency publishes a fishing threshold for it; compare with this gauge's own recent readings.
Turbidity and Water (U.S. Geological Survey)Specific conductance 1,020 µS/cm at Nov 5, 7:30 PM PST; 7-day range 955–1,060 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, 7:52 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.
