Live from USGS — the numbers
above are current rather than whenever the page was written.
The normal is the mean of every reading at this gauge within 3 days of
this calendar date in the previous years of record — 30 readings,
averaging 65.0 °F.

Computed here from the last 5 years of USGS daily values at this gauge —
1,824 temperature days over 5.0 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 72.89 °F; the fit explains
90% of the variance with a typical error of
2.005 °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.
