A runoff forecasting procedure has been developed utilizing knowledge acquired in sow research in the past 10 years. A weakness of the method is that temperature forecasts can not yet be made for periods of 5 to 30 days in advance. For several snowmelt seasons, the snowmelt was determined from actual temperature data using a simple temperature versus melt relationship. Temperature was determined by averaging data for seven index stations ranging in elevation from 2710 to 5850 feet. Reconstitution of the snowmelt hydrograph for the Feather River at Oroville was made for the snowmelt season of 1952 and 1958. Aerial reconnaissance of the basin periodically during the snowmelt season will provide useful data on the retreat of the snow-line during the melt season. Maps and charts illustrate the procedure.
