Experimental national (contiguous USA) stream water temperature forecast:

This week, stream temperatures are expected to increase rapidly in the upper Midwest and cool in the Northeast and West Coast, with modest trends elsewhere. Most of the west is a bit warmer than average and there's a hot zone in the northeast, with the rest of the country largely on the cool side. The trend over the week is largely a return to average, especially in the upper Midwest and northeast. (This forecast is for a total of 913 small [HUC-12] watersheds randomly selected from around the country.)

Warning: this is an experimental stream water temperature forecast for the upcoming week. Results are not guaranteed in any capacity. Typical errors are approximately 2.5 C (4 F).

The code used to generate these forecasts is available on GitHub at https://github.com/mines-ciroh/natl-temp-forecast (requires support for ecCodes, for which Linux is recommended). Actual weekly forecasts are made available on CUAHSI HydroShare at

Water flow in prairie watersheds is increasingly unpredictable β€” but AI could help | The-14

Water flow in the Prairies is becoming harder to predict. New AI models combined with physics could improve forecasts, helping communities manage floods.

@beynolds @ZenHeathen @jmunroe @roens good to learn about Luminescence Rock Surface Exposure Dating, and rock glaciers and their significance to #hydrology! Thanks for that excellent article.

I'm experimenting with running weekly stream temperature forecasts for a sample of streams over the US as a demo of our model, and I thought I'd look for early feedback here. Thoughts?

This week, stream temperatures are expected to remain elevated across the middle of the country, with many sites hitting around 5 C above average. However, temperatures are low on the coasts, ranging from about average to >5 C below average. Overall temperatures range from a few degrees above freezing in the north to about 25 C in the southeast. Streams are generally expected to cool off over the week, except in the Pacific Northwest. (This forecast is for a total of 913 small [HUC-12] watersheds randomly selected from around the country.)

Why forest loss is making our watersheds leak rain | The-14

Forest loss is making watersheds β€œleak” rain, study finds. Managing forest patterns can reduce runoff, sustain streams, and maintain watershed integrity.

Water, Water Everywhere – But How to Find It?

Satellite imagery is a powerful tool for mapping surface water, from the movement of rivers and streams to water levels and even water temperatures.
