when I was in LA I was amazed at how the sprinklers would be on most of the night and in the mornings the roads would be running with water.

All I could think was "this is a desert area, where you're taking water from cannot possibly sustain this"
But LA was built upon the conceit of stealing water from the Central Rockies. Mulholland was a cheating shark and Central California is paying for it.

And now that the population is so huge there is the situation of you can either have the cities keep growing wastefully surrounded by desert, or you limit the waste in the cities and keep the agriculture.
I'm not sure that either is sustainable if these rainfall patterns continue, but if the city is preferred the crunch is gonna come a lot sooner.
