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 — 28 readings,
averaging 63.3 °F.

Computed here from the last 5 years of USGS daily values at this gauge —
1,809 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 70.94 °F; the fit explains
89% of the variance with a typical error of
2.402 °F.
The water it stands in
Popple River, classified Class III (stocked) by WDNR — the nearest reach carrying that classification is 0.02 mi
from the gauge.
Snapped to NHD reach Popple River
(60002700021998), 16.0 m away. That join is
what lets the app paint this gauge's reading onto the reach it measures.
