Will California's Wet Weather Ease The Multi-Year Drought?

It's been a wet month for California.

Record amounts of rainfall and some snow have led to above normal fall precipitation. But how much is this helping with the state's severe drought?

Hydrologist Jay Famiglietti is a senior water scientist at the NASA Jet Propulsion Laboratory. He used satellite data to calculate that California would need 11 trillion gallons of water to recover from California's three year drought.

Famiglietti spoke with Here & Now's Jeremy Hobson about how much progress California is making to ease the drought and what low levels of groundwater might mean for the rest of the nation.
