These winds deposit deep drifts on the lee side of the ridges which form the south- west boundary of the West Branch and at the same time clear the snow from the windward side of the high ridge, which forms the north and east boundary of the East Branch. Sel- dom is the snow depth greater than a few inches on that high ridge during the winter, but depth increases downslope in general re- sponse to the height of the vegetation. The re- distribution of snow increases the effective depth of winter precipitation on the West Branch and reduces the effective depth of winter precipitation on the East Branch. Ttiis hypothesis will be tested during the 1971-1972 winter. Forty permanent snow measurement points have been established on the two study watersheds. Snow depths and density will be measured at each point after major storms and again several davs later. These measurements should help quantify the redistribution of snow on the area. Calibration In all watershed studies, we must deter- mine whether sufficient correlation exists be- tween watersheds so that the expected change in streamflow due to treatment can be detect- ed at a reasonable confidence level.
