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 — 31 readings,
averaging 60.8 °F.

Computed here from the last 5 years of USGS daily values at this gauge —
1,822 temperature days over 5.0 years and 1,823 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 69.39 °F; the fit explains
83% of the variance with a typical error of
1.777 °F.
The water it stands in
Mills River.
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.
Snapped to NHD reach Mills River
(25000400391036), 66.1 m away. That join is
what lets the app paint this gauge's reading onto the reach it measures.
