The other issue with well water is that as you just can't keep going deeper.Well water doesn’t help - it’s extraction, not a renewable resource.
Think of it as mining the aquifer, not drawing from a flowing river of water underground.
The problems out West are both on supply and demand side.
Flushing toilets isn’t the issue, either, it’s agriculture that uses the preponderance of the resource.
So, yeah, let your lawn die, that’s already been done. Fine/punish people for washing cars. Also…Done. Low flush toilets. Done. Low flow showerheads. Done.
It’s all been done already. Living in water - abundant upstate New York, you likely haven‘t lived with any of this, but it’s already been done. All of it.
The elephant in the room: farming.
Tell California farmers that they have to stop farming. That they lose their farms and livelihoods. Tell everyone that they can’t get fresh fruit. Fresh vegetables.
That’s the problem. Kill off the farms, and you solve the water problem.
But you would create food shortages across the country.
As a consumer, as a buyer of produce, you are part of creating this water shortage by buying food that’s grown in California, using water from the Colorado River.

Growing demand for deeper wells is tapping ancient water reserves
Communities that rely on the Colorado River are facing a water crisis. Lake Mead, the river's largest reservoir, has fallen to levels not seen since it was created by the construction of the Hoover Dam roughly a century ago. Arizona and Nevada are facing their first-ever mandated water cuts...
