Not an expert, but a more-than-casual-observer as someone who has lived on the water (literally and figuratively).
A core part of the problem is things like the farming in California that uses excessive amounts of water, which is already brought in from very distant regions.
I don't think there is a way to distribute the fresh water supply equitably if you have various regions and industries that insist on being highly inefficient and wasteful. California is certainly not the only example, there are lots of places trying to grow crops in illogical places, water supplies being polluted by industries, etc.
The problem isn’t just farming in the desert. The problem is all those people living in the desert in the first place. There is a reason the Spanish then the Mexicans did almost nothing to settle and develop California. It was massive water projects by the U.S. Army Corps of Engineers that made modern California possible.
I'm no fan of cities in deserts, but farming is by far the much, much, much larger problem.
How much has the infrastructure improved since then? I see on TV that some of California has snow and flash flooding. Are there attempts being made to capture that, or soak it into the ground? Or is it cheaper to keep using the old projects?
I see on YouTube that there are parts of Texas you can buy for peanuts because ranching doesn't work there any more. I gather that the cows eat so much of the ancient grassland away that the soil washed away and now we have flash flooding? Then I see terrible flooding in the main rivers. I wonder if it is because governments are (or were) good at big centralised water projects, but spending for thousands upon thousands of swales and check dams to be built is harder, and less sexy?
Agriculture in the SW uses 75% of all water that flows through and/or falls upon the landscape.
Residential use is 7%, about the same as evaporation and retail/commercial/power-production.
The people living in the desert are not the problem when it comes to water.
It's really intertwined. While California exports a LOT, people need to eat and the economies of scale lean towards eating locally grown crops. Living in a desert creates some degree of demand for local crops.

California isn't even the problem. They're rich enough and big enough, (and fortuitously situated enough), that they just crank up desal plants and go happily on their way.
What about the rest of the west?
Arizona? New Mexico? Nevada? etc etc
Water needs to be brought in from somewhere? Who's going to pay for that? How do you do it safely, sustainably. And on and on.
I know people forget the rest of the west a lot. (Or maybe they just don't care about us as much?) But it's actually more of an issue in those places than it is in California.
A personal illustrative story. I used to live in Scottsdale. The water issue is such common knowledge out there that people started trying to get into the magic zip code. (Phoenix sits on like a gazillion years worth of water that they squirreled away.) I had moved into the magic zip code just about 1 year before everything went crazy. As it happened, about 18 months after we moved to that zip, we decided to move back to the Great Lakes region. Fully expecting to lose money on the house. But the word had got out on that zip code, and the final offer was over 60% more than we'd paid just 18 months prior.
That gives an indication of how even individuals are thinking. It just kind of felt like a lot of people, governments and organizations know there will be an issue, but money is gating everyone's ability to do anything about it.
Whereas of course, money's not as much of an issue in California.
I think large parts of the west will need help in the future. Or people will need to pay significantly more in taxes to live in those places.
It can't go on forever the way it has been. That much is certain.
> Water needs to be brought in from somewhere?
Only for agriculture. Residential water needs are 7% of the available water.
Also, the aquifers under/near Phoenix are not segregated by zip code.
Also, higher taxes don't make water when there isn't any.

Everything I've read about desalination is that it is not really economically feasible. Has that changed? I don't think CA can "just crank up desal plants" in a practical sense.
