Arizona and Nevada could also see cuts, while other states would continue to make cuts based on drought conditions to ensure that enough water is sent downstream to meet their legal obligations. Given the transition into spring, the Western U.S. is running out of time to build the snowpack before the usual peak in seasonal snow accumulation around or soon after April 1. When the runoff starts, Curtis expects to fill the 381,195-acre-foot McPhee, provide full water allocations to area farmers, release water for rafting and store carryover for next year. Snow Surveys and Water Supply Forecasting. This winter, in the water-towers of the west, storms have dropped more than double the average snowpack in some Colorado mountains.
