Recent work performed on the analysis of 1 day's contribution to the snowmelt hydrograph is summarized. The data are part of the Cooperative Snow Investigation of the USBR-USFS at Frasier Experiment Forest, and cover separately the St. Louis Creek and the Fool Creek drainage basins. The total runoff from each day's melt is defined and all measurements are correlated to the total volume of runoff from the one day's melt using the combined data from 1948 and 1949. The relationship of the first day's volume to the total volume is plotted. A definite break is apparent with the double mass curve of accumulated first day volumes vs. accumulated total daily runoff at the point representing the maximum runoff for the year. It is suggested that the 2 parts of the melt season, before and after the peak, be considered separately in establishing correlations.
