Growing demand for water supply coupled with increasingly frequent drought and flood risk requires optimal
management of the Nation's available water resources. Forecast Informed Reservoir Operations (FIRO) is a
research-and-operations partnership strategy that capitalizes on scientific improvements in weather and
hydrologic forecasting to improve reservoir management. The FIRO research program now encompasses four
sites at varying stages of assessment, and the emerging development of a FIRO Screening Process to assess
suitability of the full USACE portfolio of dams.
The FIRO research program is in response to an update to the US Army Corps of Engineers Water Control Management Engineer Regulation (ER 1110-2-240) that allows for forecasted conditions to be used in planning water management operations. At FIRO sites, collaborative teams of stakeholders and researchers rigorously assess the possibility of using atmospheric and hydrologic forecasts in making release decisions. Where viable, FIRO improves water supply availability, flood risk management, ecosystem benefits and other project purposes.
