Coming soon: Forecasts for Snow Water Equivalent (SWE) & soil moisture

In snow-dominated basins, forecast accuracy depends on snowpack and melt dynamics. That’s why we’ve been experimenting with training HydroForecast to predict land surface conditions like SWE and soil moisture. Early results of these tests show forecasting SWE + soil moisture strengthens streamflow forecasts and enhanced the model's internal representations of hydrologic processes.

HydroForecast visits Sacramento, California

Last month, the HydroForecast team met with California water leaders in Sacramento—including DWR, State Water Resources Control Board, State Water Contractors, and CNRFC—to discuss applications from climate-adaptive forecasting to FIRO, water rights, allocations, groundwater recharge, and flood forecasting. We also met with Bureau of Reclamation and Placer County Water Agency to see how their operations teams use HydroForecast for daily planning and real-time decisions. Read about it in Alex Truby's post on LinkedIn.

Monitoring atmospheric rivers on the West Coast

November brought a series of strong atmospheric rivers (ARs) to the West Coast, and another wave of heavy AR-induced precipitation is predicted this week. We’re keeping a close eye on our forecasts in this region—some areas may see some of the highest flows in the past 5 years!

Behind the scenes: Snow, water supply, and machine learning models

Check out a behind the scenes look into the research and development (R&D) work from the HydroForecast team in our recent blog about snow data’s impact on flow forecast performance.

Western energy markets are set to evolve in 2026

With the Extended Day-Ahead Market (EDAM) set to bring major updates to Western energy trading in 2026, we are tracking these market changes closely and exploring how reliable forecasts can support more confident and informed operational decisions. Read more: Navigating the new EDAM market, CAISO reforms, and the value of precise short-term forecasts.

Webinar: Proactive trespass detection for utilities with Lens

The Lens team here at Upstream Tech is hosting a short webinar on spotting trespass and encroachment early with satellite imagery and AI, especially for remote ROW corridors and properties. Pass the invite along to your ROW, lands, or asset management colleagues who deal with access or encroachment issues.
