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 64.3 °F.

Computed here from the last 5 years of USGS daily values at this gauge —
1,808 temperature days over 5.0 years and 1,824 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 72.3 °F; the fit explains
91% of the variance with a typical error of
1.268 °F.
The water it stands in
Tinker Creek, classified Class VII (stocked holdover) by VDWR — the nearest reach carrying that classification is 3.3 mi
from the gauge.
Snapped to NHD reach Tinker Creek
(15000100039939), 6.2 m away. That join is
what lets the app paint this gauge's reading onto the reach it measures.
