Explain the importance of winter storms in the western United States.. Geography

In the western United States, m.ost water arrives in winter storms, which swoop in from the Pacific and dump

snow atop the region’s mountain ranges. Mountain snowpack serves as the West’s water tower, and over the

past century Westerners have built hundreds of dams to catch and store snowmelt as it fills the region’s rivers in

spring. Mountain snowpacks are frozen reservoirs, their spring melt supplying as much as 75 percent of the

West’s water.
