Abstract

A need is shown to develop a forecasting procedure of seasonal runoff as early as February 1st. A scheme is developed from snow survey data and streamflow for the Snake River and tributaries and also for stations along the Columbia River below the Canadian border. Records from 39 snow survey courses were analyzed in relation to streamfflow records over a series of years where parallel records are available. Although the scheme is feasible, the variability of the occurrence of storms was too uncertain to place much reliability in the procedure. The need for longer periods of records is much in demand for such forecasts. A month to month or day to day procedure could be more efficient.
