USGS publishes no daily statistics for this gauge, so the reading is not compared with the record.

Falling over 24 hours: discharge down 13.2%, from 7.74 to 6.72 ft³/s. 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 62.2°F now; the highest in the last 24 hours was 63°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.
