Map of USGS gauge 11224000 and the river around it
Where MF SAN JOAQUIN R NR MAMMOTH LAKES CA sits and our water's map point.
Under CDFW's 67°F line. Water 41.7°F now; the highest in the last 24 hours was 42.8°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: 7.5–20 ft³/s (middle half of 16 years of record). Now: 7.28 ft³/s, below normal.
Below normal for this date. 7.28 ft³/s is between the 10th and 25th percentiles of daily mean flow for Nov 5 at this gauge over 16 years of record (2011–2026): 10th 5.5, 25th 7.5, median 12, 75th 20, 90th 96 ft³/s.
Daily means on record for Nov 5: lowest 5.53 ft³/s, highest 128 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% 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.
This gauge is on the same river as our page for Middle Fork San Joaquin River, but no agency page we read lists its species.
Cold water. Water 41.7°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)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, 6:59 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.
