Simply cutting back on water usage won't be enough. So much is used for farming and sanitary purposes that when the dams and aquifers fail the major cities will have to be abandoned. Unless of course you use the last of the resources to build a string of nuclear stations to desalinate the ocean.[/quote]
You talk as if water is a finite resource ,once it is used it is gone. In reality water is used then discharged or evaporated back into the environment through rivers and oceans... [/quote]

The problem is not that it falls back, but WHERE it falls back. When old civilizations die out because of droughts and the the people migrate, they go to areas where there is water. As far as these big dams in the US are concerned water is a finite resource, if not then all that water taken to irrigate the farms would have evaporated back into the atmosphere and rained back over the catchment, refilling them. But it hasn't has it. The dams are drying up.
Someone suggested above that we desalinate the ocean, such a delusional idea when we can't even afford to repair bridges and roads anymore. But that person has a job in said industry, so their opinion is based on the fact that they would really like to see the industry go forward in leaps and bounds so they can get promoted and retire rich. A lot of what is discussed here is pure hypothetical dreams. Sure it looks good on paper, once you ignore the fact that we are running out of oil.
If I was a member of the Elite class, managing the western world's affairs, I am sure I'd do just as they are doing right now. Feathering my own nest with total disregard for the millions of little people who will suffer when things like the dams go offline. That is how the world works and always has been, and any modern ideas of egalitarianism are chuckled at in places like Davos.[/quote]

I will believe it when I see it working on a commercial scale.
I dead Easter Islanders did something similar, but they used to plant a plant next to a biggr rick so the rock would condense some water onto the seedling.

This argument about the sedimentation making these reservoirs unusable is a complete crock of $#!*.

And you would think that sediment would help make the basis of soil. It is broken up enough. It could be added to other dirt and made to be part of a scheme. It isn't like the sediment has to be brought back to where it came from. It only has to be placed on the canyon rim. Up there, anything can be done with it.
