Jay Famiglietti, a senior water scientist at the NASA Jet Propulsion Laboratory in California, made a dire warning in March: there is only one year's worth of water left in the state's reservoir storage and river basins.
Famiglietti said even nature's oldest water backup supply —groundwater — could be gone soon after the reservoirs dry up.
About 38.8 million people live in California, which produces much of the United States' food. California's drought is throwing the ecology of the region into crisis, and ordinary people are scrambling for ways to help.
