Having lived there most of my life before escaping when I retired, I know a bit about the water situation. Los Angeles is a mild desert with the best weather in the country, but no water. At max it had enough water to support 250,000 and the population is somewhere around 18 million in just the four counties of LA, Orange, Riverside, and San Bernardino. Around 1900 they diverted water from the Owens Valley, and the city began to grow. That was done by Bill Mulolland, for whom they named Mulholland Drive. Then he built 7 large reservoirs to store the water. Then they diverted water from the Colorado River. Then they built the California aqueduct- essentially a concrete river running all the way from the Sacramento River Delta into LA. They had to do all that to keep pace with the population, but eventually they ran out of new sources for water, and the population just keeps growing. Their crazy politicians don't know their ass from a hot rock, and there are plenty of those laying around. They are between the proverbial hot rock and a hard place.
