Case Study: Early warning and accurate peak flow predictions during historic floods

During high flows and shifting weather, traditional forecasting tools often fall short. Gauge outages, equipment failures, and rapidly evolving storm tracks can leave operators without the reliable data they need to make timely decisions.

In December 2025, a series of atmospheric rivers pushed Pacific Northwest reservoirs from critically low levels to historic flood conditions within days — one of the most challenging operational scenarios water managers in the region had faced in years.

HydroForecast delivered early peak flow warnings days ahead of standard forecasts, maintaining accuracy even as gauges failed and storm tracks shifted. The results speak for themselves.
