Map of USGS gauge 11264500 and the river around it
Where MERCED R A HAPPY ISLES BRIDGE NR YOSEMITE CA sits.
Under CDFW's 67°F line. Water 43.9°F now; the highest in the last 24 hours was 44.8°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) (California Department of Fish and Wildlife)Normal for Nov 5: 8.5–66 ft³/s (middle half of 111 years of record). Now: 18.2 ft³/s, normal.
Normal for this date. 18.2 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 111 years of record (1916–2026): 10th 4.6, 25th 8.5, median 18, 75th 66, 90th 121 ft³/s.
Daily means on record for Nov 5: lowest 2.15 ft³/s, highest 222 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 (−7.1% 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.

Below NWS action stage. The National Weather Service reports this gauge below its action stage. That is not a statement that wading is safe.
Flood categories: action stage, minor, moderate and major flooding (National Weather Service)Cold water. Water 43.9°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.
