Abstract

Snow survey water content measurements are used as a basis for forecasting irrigation water supply, together with other factors closely allied with snow melt. Four factors are listed, (1) rainfall during the runoff period, (2) rainfall during the fall months before snow fall, contributing to soil priming and groundwater recharge, (3) deep percolation losses, (4) evaporation and transportation losses and sublimation of the snow pack. Measurable factors are by correlation coefficient values. A regression equation is developed and the least squares line is drawn through the plotted points on the graphs as a means of visual inspection. A discussion of the results of the study is included in the text of the paper.
