The redesign of the elevation zone computation routines of the watershed model of the SSARR system will make possible operational continuous simulation of snow accumulation and ablation for various elevation bands. Volume runoff forecasts can be prepared by the model using the model conditions for any date and subsequent temperature and precipitation sequences of previous years.Correlation between snow course observed snow water equivalents and simulated snow water equivalents in model zones are excellent. These results suggest combined use of temperature and precipitation model and observed snow course data will produce improved water supply forecasts. The model results will be valuable for (1) evaluation of snow courses and network design, (2) definition of snow climatology, and (3) interpolation and extensions of snow course records.
