Western Snowpack

The western American snowpack is nature’s reservoir, providing 60-70% of the region’s water supply. Winter precipitation is stored there and is released slowly during the spring and summer. The snowpack feeds the region’s rivers, fills reservoirs, supports irrigation for agriculture, enables hydropower, and sustains ecosystems. After the warmest winter on record for many states and a major heat wave in March that left almost no snow in many places, there is real trouble ahead.
