The problem is that the snowpack is part of the storage system. The warmer summers melt the snowpack sooner in the year, reducing the amount of water being stored. I've hiked in winter snow in August, and even September, but not for a few years. We survive that because the reservoirs are designed to hold more than a year's worth of water demand. But the integrity of the system depends on all the parts operating to some degree.
