This is, perhaps, the most charged sentence ever written on the innernets:

Eventually, [the Ogallala and Central Valley Aquifers in the US, along with a number in China and India, which are being drained at a rate that far exceeds their recharge] will tail off to [reach usage rates] something in the neighborhood of their recharge rate.

Sensible! Except the recharge rate for the Ogallala, which, like all of these aquifers, charged over geologic time frames, is ~0.024 inches per year (in the Texas portion, anyway; Kansas manages a rate approaching 6 inches).
Good luck with achieving a usage rate below that with a population of ~0.5 million folks (per 2000 census) and a large, water intensive agricultural economy (in fact, ~30% of the groundwater destined for agricultural use in the entire US comes from this very same place).
And it’s not just Texas that’s sort of attached to drinking the stuff. The Ogallala services a bunch of population centers right up the red core of these United States. As in: they get their water from it exclusively. Because no other source exists. 82% of those folks in its boundary, which is all of Nebraska, large chunks of Kansas and Oklahoma, and the panhandle of Texas.

Anywho: peak water. Everybody west of the Mississippi better start thinking, hard, about where their water is going to be coming from long term. I, for one, am all for letting the market decide what the price of an acre foot of water ought to be in, say, Nevada. After all, we’ve been underwriting their water-drenched lifestyle via Reclamation and Corps of Engineers projects for decades. We’re told the days of “Big Government” are at an end. Fine. We’ll start with repricing the desert West’s water supply to a acre foot pricing schema that might actually pay for a few of these projects this century and properly move use to the family farmer the damned things were meant to benefit in the first place. Then we’ll see just who wants dread guvmint all up in their grill.
