The webpage provides access to various data and information from the California Nevada River Forecast Center (CNRFC). The data and information are related to the mission of the NWS Water Resources Services Branch and National Water Center, which is to provide river and flood forecasts and warnings for the protection of lives and property, and to provide basic hydrologic forecast information for the nation’s environmental and economic well-being.
The CNRFC provides hydrologic guidance for time scales that vary from hours (flash flood guidance, flood forecasts, and reservoir inflows), to days (flood forecasts, reservoir inflows, and short-range ensembles), to weeks (short-range ensembles and water resources), to months (water resources). To develop this guidance the CNRFC employs a host of hydrologic models and procedures that range from simple to complex and empirical to process simulation.
The data covers the hydrologic area of responsibility for the CNRFC (approximately 250,000 square miles).
