Forecast Summary

Stream Water Temperature = SWT. All metrics refer to daily or weekly average SWT at a site, so, for example, "national average maximum" is the national average of the maximum daily average SWT this week at each site.

The static plots below provide more information about weekly trends and temperature anomaly (departure from the normal temperature at this time of year.)

This forecast dashboard is developed and maintained by the Hogue Research Group at Colorado School of Mines (Daniel Philippus, Claudia R. Corona, and Terri S. Hogue) with funding from the NOAA Cooperative Institute for Research to Operations in Hydrology. If you use this dashboard in your research, please cite the HydroShare Resource and the TempEst-NEXT paper.

Note: forecasts are generally for smaller tributaries. If a forecast is at a confluence, the mainstem temperature likely differs. Note also that these forecasts are from a generic, national model. It is typically effective everywhere (e.g., mountains, deserts, forests, cities), with typical errors around 2-3 C (4-5 F), but any given site may have large errors. Forecasts just downstream of a reservoir, hot spring, or wastewater discharge may be particularly unreliable.

The above map is interactive and can be panned and zoomed. Hovering over a point will display its information in the top right; clicking will produce a persistent pop-up with the same information.
