The Western US is already rationing water, with the potential for summer to occur months before it comes to fruition. According to a spokesperson for Denver Water, the city cannot rely on snowpack as it typically does to replenish its reservoirs. This is due to a serious situation where public access to the water may be limited to one day a week. The issue is exacerbated by the increasing use of "one-hour fuels" by grasses that can dry without a winter-long drought, which are often more resistant to fire. These fuels have also been exacerbated by warm temperatures, low relative humidity, and frequent wind storms throughout the winter in much of the Rocky Mountains. The Bureau of Reclamation has given states until October to conserve more water, and has estimated that water managers in the basin must conserve an additional 1.7 million acre-feet to keep Lake Powell's levels from falling so low they can't turn hydropower turbines at Glen Canyon Dam in Arizona.
