This gauge is not sending water temperature — USGS carries no water-temperature series for it at all. USGS still answers for it, with the last value it ever sent and nothing to say the sensor has gone, so nothing on this page is presented as a current reading. Everything below — the record, the monthly means, the thirty-day chart — is the gauge's own history and is unaffected.

Daily means from USGS. A gap in the line is a gap in the record.
