State-of-the-Art Water Intelligence for Decision-Making in Hydropower
Wegaw delivers accurate, water intelligence with AI-powered snow water storage estimations and streamflow forecasting, helping hydropower operators and traders optimise generation, reduce risk, and make better market decisions.






Snowpack patterns are immensely complex – simple simulations based solely on temperature and precipitation are not enough to accurately quantify snowmelt contributions, either in the short or long term.
Wegaw uses satellites, ground stations and atmospheric model outputs to deliver high-resolution, daily estimates of snow water storage and streamflow – powered by AI models trained on billions of high-fidelity environmental and meteorological data points.
With forecast horizons ranging from one hour to over 12 months, WeGaw enables smarter scheduling, optimized generation, and more accurate market positioning.
Solutions Built For Modern Hydropower
Snow Water Equivalent
Daily Snow Water Equivalent (SWE) estimates to quantify stored water, not just snow depth, for more accurate inflow forecasting.
Our AI models deliver high-resolution, daily updates on Snow Water Equivalent (SWE), quantifying how much water is stored across your catchments, enabling more accurate water resource forecasting
Streamflow
Streamflow forecasts built for generation and market strategies
We combine curated weather forecast ensembles with proprietary SWE data to provide streamflow forecasts across multiple time horizons, ranging from hourly to seasonal.
