California's population just about doubled since 1970 (45 years ago). In the mid 1970s, it suffered a water shortage. In 1970, it had about 34 million acre-feet of water reservoirs for just under 20 million people. Today it has 42 million acre-feet of water reservoirs for more than 38 million people.
From the Los Angeles Times: "The flow of water from shower heads and bathroom faucets in California will be sharply reduced under strict new limits approved Wednesday by the state Energy Commission. Current rules, established in 1994 at the federal level, allow a maximum flow of 2.5 gallons per minute from a shower head. Effective next July, the limit will fall to 2.0 gallons per minute and will be reduced again in July 2018, to 1.8 gallons, giving California the toughest standard of any U.S. state."
The Golden State is about to become the Stinky State because politicians would rather spend money on welfare for illegal aliens than on infrastructure.
