Short-term
Improve day-to-day distribution and operational decisions with hourly forecasts for the next 10 days.
For water utilities & agencies
From snowpack to spillway, forecast what's coming
Water utilities and agencies manage some of the most consequential water decisions with the least room for error. HydroForecast gives your team the reliability and early warning to keep communities safe.
Plan for every season, prepare for every extreme
Water supply reliability
Plan every season with confidence
Reduce costs from over-allocation or under-utilization, and adjust distribution based on a reliable read on what's coming — including basins where snowmelt drives seasonal supply — not just historical averages.
Safety & emergency response
Reduce risk before the water rises
See further ahead so your team can act, not react — proactively manage flood risk, reduce last-minute releases, and streamline emergency planning across the full range of extreme weather your team responds to.
Regulatory compliance
Confidently meet water-quality standards
Meet environmental flow regulations and reporting requirements with proactive alerts, and extend consistent flow information to basins where gauge coverage has always been sparse.
Ungauged coverage
consistent flow information where gauges fall short
Explore ungauged forecasting →One forecast partner, every supply horizon
Whether you're managing today's distribution or next year's allocation, every forecast — short-term, seasonal, or annual — comes from the same system.
Short-term
Seasonal
Plan water-supply allocation and reservoir operations with daily forecasts out 90 days.
Annual
Support long-term planning and infrastructure investment with daily forecasts up to a year out.
Proven through drought and flood extremes
Sonoma Water serves over 600,000 residents across Sonoma and Marin counties, managing a watershed that swings from multi-year drought to a 1,000-year rainfall event, as it did in November 2024.
For years, Sonoma Water has used HydroForecast across reservoir operations and seasonal planning, alongside a research partnership with USACE and Scripps on Forecast-Informed Reservoir Operations at Lake Mendocino and Lake Sonoma.

HydroForecast was 40% more accurate than the RFC during that November 2024 event, predicting peak flow 24 hours in advance.
Working with the agency behind the data you already trust
Leading U.S. agencies already benchmark against NOAA's River Forecast Centers and National Water Model. Our new CRADA with NOAA's Office of Water Prediction puts AI-based forecasting to the test on those same water management, flood response, and water-quality decisions.

Extremely important in our planning toolkit
Streamflow forecasts are an extremely important component of our planning toolkit… And with that, it's always important to understand snowpack dynamics, soil moisture, total precipitation — like what's behind HydroForecast.
Why water utilities & agencies choose HydroForecast
Built for the extremes
that strain systems
Theory-guided AI stays accurate through droughts, atmospheric rivers, and snowpack anomalies — not just steady-state conditions.
Coverage where gauges
don't exist
One foundational model reaches ungauged tributaries and basins without monitoring infrastructure — not just where sensors happen to exist.
Powered by deep hydrology experience
HydroForecast draws on a team with deep, hands-on experience in hydrology and hydrologic modeling — expertise embedded directly in the model, not layered on afterward.
