The Colorado river should be serving cities and agricultural areas near it. The Sierras and desal should be serving the rest of California. We have built all this infrastructure to move Colorado River water way beyond the area it can serve. That infrastructure needs a huge amount of electrical energy (1/5th of the electricity produced in the state!) and a lot of maintenance. It would make a lot more sense to just move electricity instead of water. Almost all the population in California lives in the coastal cities, Desal plants can connect to existing water distribution networks.

In the long run, warming should put more water into the atmosphere, But it will also change precipitation and wind patterns in unpredictable ways. Farmers in North San Diego are trying to leave the San Diego Water Authority so they can join Riverside County's Water Authority, that has lower rates. San Diego has slightly higher rates, but it also has greater stability. These guys are avocado growers who need a minimum amount of water to produce, and they need it all the time. If they get cut off by the water district for two weeks, their production goes to zero for at least the next year. Maybe two years. I predict the end of avocado production in Fallbrook if they succeed, because at some point their new water district will shut down their water. The rest of North County will still have 50 million gallons per day of desal water being made by the Carlsbad plant.

We're flying electric helicopters on Mars yet you can't turn on your clothes dryer in Texas. That's because scientists are in charge of Mars, and Republicans are in charge of Texas.
