Never fear. Most of the decline in the Ogallala Aquifer is in northwest Texas near the headwaters of the Brazos River and north into southwest Kansas to the Arkansas River. North of the Arkansas River and even around the edges in Texas, the Aquifer is generally stable to increasing in water in the recoverable zone. So, since in 20 years global warming is also going to greatly increase the temps north of Arkansas River it just means the people in northwest Texas that need water (mostly farmers and ranchers) will have to do what the Pueblo Indians did - move. As for other than farmers and ranchers, there is not much there now except oil wells and oil wells and oil wells and we are going to get rid of the need for them anyway. We can always use the land for wind farms and solar panels ( maybe the US taxpayers won't lose another $737 million on them) . https://www.greentechmedia.com/articles/read/americas-concentrated-solar-power-companies-have-all-but-disappeared
