Water temperature for trout, salmon and steelhead

• Under CDFW's 67°F line. Water 59.5°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.

Safety

• Cold water. Water 59.5°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.
