Droughts are why William Mulholland provided southern California with some long straws sucking water out of distant areas. The Metropolitan Water District improved on this position in 1934 by building the Parker Dam across the Colorado River and an even longer straw taking the water back to Los Angeles and putting it to immediate "beneficial use", which at the time was farming. Today it's mostly urban use.

Fortunately U.S. water law recognizes the right of the "First Beneficial User" being superior to all others, so a lot of places will go dry before southern California loses even a drop of water.

The drought today has not yet reached the magnitude of the drought which hit the American Southwest in the 13th Century, causing the Pueblo cities to be abandoned.

The very long straw from the Colorado River.

It is true that decades long droughts are part of the normal climate variability of the Earth.

It its trivial to prove this, elementary school students should be taught this fact instead of the AGW creed,

The only constant about the Earths climate is that some regions will suffer long droughts and other will have increased rainfall.

Only 2000 years ago North Africa was the bread basket of the Roman Empire.

LOL: That NOAA study only goes back 120 years
"since official measurements began in 1895. "

Here is an article with a more historical perspective:
mercurynews.com

Through studies of tree rings, sediment and other natural evidence, researchers have documented multiple droughts in California that lasted 10 or 20 years in a row during the past 1,000 years -- compared to the mere three-year duration of the current dry spell. The two most severe megadroughts make the Dust Bowl of the 1930s look tame: a 240-year-long drought that started in 850 and, 50 years after the conclusion of that one, another that stretched at least 180 years.

Heck you might want to consider that the "normal" climate for California just might be mega-drought rather than the abnormally good rainfall that the state has received over than past 100 years.
