Larger than usual snowpack in California gives hope of reprieve in drought

Extreme weather filled the Sierra Nevada snowpack, which provides roughly a third of the state's water supply

Extreme weather hammered California through the first weeks of the year - but also offered a badly needed reprieve. The deep snow dumped on the Sierra Nevada during a series of strong storms left the state with a robust water savings account of sorts.

As the weather warms over the spring and summer months, the melting snow fills rivers, streams and reservoirs long after California's rainy season has ended. Considered one of its most important reservoirs, the snowpack provides roughly a third of California's water supply. That's why the white-topped mountains and piled-high powder are a signal that the state may be better set up to handle its water woes than it has been in years.
