It is a little scary. A friend of mine in Phoenix is considering moving back to Ohio because he is afraid the water shortage will decimate housing prices and destroy the economy in Phoenix.
I do think that there's a decent likelihood that Arizona will not exactly be the best place to live after 20-30 years' more global warming.

I have lots of family in Ohio, and many are farmers. It isn't that uncommon from them to have to drill new wells because they are drying up, too.

There s a lot of droughts going on all over the world.

If these drought conditions continue to worse around the world that would force the world to place a higher value on water. If you have ever been to the Caribbean you have probably noticed people that own homes there are very strict on water usage. They live on islands without fresh water rivers. Some capture and collect rain water that falls on their property. Others pay to have water delivered to them, which can be expensive.

“In the Virgin Islands more than 90% of the population utilize rainwater harvesting.”
https://cgtc-usvi.org/rainwater-harvesting
Rainwater harvesting involves collecting rain from rooftops and storing it in cisterns, usually built into the house foundation. During times of heavy rainfall the cisterns may overflow and run-off. On the other hand, in times of low water levels residents may need to purchase water from private vendors, which can be costly and difficult for those living in hard to reach areas.

Then again they do get a lot more rainfall there than say Phoenix that has over 300 sunny days a year. If Phoenix is forced to get rid of pools, man made lakes and stops watering lawns that would help cut water usage, but make Phoenix not quite as attractive.

There is always a chance that the drought will end. I lived in Phoenix in 1978 when we had a 100 year flood that wiped all but one bridge across the Salt river out. While we are experiencing drought some places are experiencing floods. Mother Nature will do what she wants, when she wants. El Niño could make an appearance.

Lakes are drying up everywhere. Israel will pump water from the Med as a solution
https://www.cnn.com/2022/08/19/middleea ... index.html

Despite its name, the Sea of Galilee in northern Israel is actually a freshwater lake, and it's one that has sustained life for millennia. Climate change and unsustainable water management are leaving lakes dried up all over the Middle East and beyond, but the Israeli government is hopeful it has a solution: It plans to pump water from the Mediterranean sea, take the salt out of it and send it across the country to top up the lake when needed.

Israel has plenty of expertise in desalination. As a water-insecure nation, it has for more than two decades been taking seawater from the Mediterranean and treating it through a process called reverse osmosis, essentially taking the salt out of the water to make it drinkable. It's a process that other parts of the world, including California, have turned to in times of drought, but in Israel, it's an everyday reality. Five desalination plants along the coast now provide nearly all the tap water for the country's 9.2 million people.

"They looked into the future climate change, and what's going to happen [with] rainfall in this area, and also looked at the increase in population and projected increase in demand of water," Gideon Gal, senior scientist and head of the Kinneret Limnological Laboratory, told CNN. "And they realized that 30, 40 years from now, there's going to be a serious problem in maintaining [water] levels in the lake, and maintaining water quality unless something is done."
