This gauge is not sending water temperature — USGS carries no water-temperature series for it at all. 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 322 days of this gauge's own record, June 2021 to September 2023. 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 ±2.6 °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 — 7 readings, averaging 59.2 °F.

Computed here from the last 5 years of USGS daily values at this gauge — 246 temperature days over 2.0 years and 1,110 flow days. These are not USGS-published normals, and a month with fewer than 20 days of record is left blank rather than averaged. This gauge has under 3 years of temperature record, which is why no normal is compared against above.
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 66.44 °F; the fit explains 69% of the variance with a typical error of 2.616 °F.
The water it stands in
Bois Brule River, classified Class I (wild) by WDNR — the nearest reach carrying that classification is 0.06 mi from the gauge.
Snapped to NHD reach Bois Brule River (60003700017042), 93.8 m away. That join is what lets the app paint this gauge's reading onto the reach it measures.
