This gauge is not sending water temperature — it has sent no water temperature for 315 days, since 17 November 2025.
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.
The figure above is modelled: this gauge's own fitted line, its intercept plus its slope against the 3-day mean air temperature over it, fitted on its own daily record,
built from 1,055 days of this gauge's own record. A gauge stopping does not unmake what
it recorded while it ran, and the record below is the same record the line was fitted on. Its
scatter against that record is ±1.7 °F, and it is a statement about
what this water usually does at this air temperature, not about what it is doing.
Everything below — the record, the monthly means, the thirty-day chart — is the gauge's own
history and is unaffected.
The normal is the mean of every reading at this gauge within 3 days of
this calendar date in the previous years of record — 28 readings,
averaging 50.1 °F.

Computed here from the last 5 years of USGS daily values at this gauge —
1,506 temperature days over 4.1 years and 0 flow days. These are not USGS-published normals, and a month
with fewer than 20 days of record is left blank rather than averaged.
What this gauge predicts
This is one of the gauges this site fits an air-to-water model against, which is how the map
colours water that has no gauge on it. July mean 74.03 °F; the fit explains
87% of the variance with a typical error of
1.701 °F.
We hold no coldwater classification for this river, so the page makes no claim about
one. The gauge is here because it stands close to water that does carry a designation.
