Abstract

The relation between streamflow and water content of the snowpack is affected by many factors, such as topography, temperature, wind, and soil moisture conditions at freezing. Forecasts based on snow water content have varied as much as 24% from actual flow since 1935. It is assumed that various responsible components can be evaluated within limits and that corrections may be determined to permit an accurate forecast of the seasonal (April - July or Sept.) probable water supply. The photographic method of measuring snow (See WSC 41-37) and relating to streamflow to areas measured by a grid over photos has had promising results. The record is too limited at this time for final conclusions.
