Is gonna get ugly…
According to the U.S. Geological Survey, the Ogallala Aquifer, which provides about 30 percent of the groundwater used for irrigation in the United States, is being drained faster than it can recharge. As with many above-ground lakes, that means it could one day run dry.
The USGS has reported that groundwater levels in some areas of the Ogallala – which runs from Texas to South Dakota – have dropped 200 feet since large-scale irrigation began. NASA’s Earthdata analysis found that overuse has led to significant declines in Ogallala groundwater levels that threaten its sustainability.
Water management is becoming a critical issue for farmers and ranchers. Even in Texas, people are too familiar with electricity brownouts and blackouts that sometimes last for days. But when a reservoir or an aquifer runs dry, the wait can be far longer.

While ‘we’ don’t directly get water from it, we do pull some from the Seymour Aquifer, see below-

It is what’s called an ‘unconstrained’ aquifer, in that it is geographically diverse and not connected. We do get ‘some’ municipal water from it, but most of our water comes from surface lakes.
Which makes us susceptible to water rationing when it doesn’t rain (drought) and the water levels in the lakes fall. We haven’t had a ‘water emergency’ since I’ve been here (10 years now), but I know we’ve come close at least once.
As a friend of fond of saying, water is for fighting, and whisky is for drinking. And I think we’re about to get in a fight… sigh…
And it’s not just here in Texas. The whole Colorado River Compact is apparently up for discussion, due to the mandatory ‘rationing’ of water downstream. There is also the ‘issue’ of senior water rights, granted in the 1800s that predate any agreements and outrank the agreements.
And the major lakes/water supplies are low, due to little rain and virtually no snowpack in some areas.
All I can say is be smart folks…
We also have a problem with the Snake River aquifer here in South Idaho as well. For decades the aquifer was considered ‘unlimited.” Not any more. With most of the Snake River itself allocated for irrigation, power generation, and aquifer recharge, a dry winter like this last one will strain the aquifer badly. Yeah, times are going to get “interesting” in that Chinese curse way.
I’m gonna call it…. the world will run out of water before it runs out of oil. and, like my daddy forecast 30+ years ago, the next major war will be over water, not oil.
Wichita County, KS (far western Kansas) has had to switch crops because their wells have dropped so low and the cost of pumping is so high.
Most of the Ogallala does not recharge. The Nebraska Sandhills, and some places in the southern end in Texas (also sandhills) do get recharge when it rains enough, but the bulk of the formation is fossil water. I’ve read forecasts that if all pumping ceased today, it would be over three thousand years before it recharged, IF it can, given compaction due to pumping. The book _Ogallala Blue_ is a good, big-picture look at the formation and the challenges.
[Full disclosure: My masters and PhD were both related to the Ogallala and other water sources on the Great Plains.]
There are farmers in southwest Kansas that no longer have water under their property. Knew a farmer in the 80s that had to go to Ulysses to fill a tank truck for domestic water on the farm. In the early 90s read a newspaper article about a farrmer in Wallace county that went over his grandfathers records. Realised that Gramps did better dryland farming. He went back to doing that.
NRW- I’m not surprised.
Dennis- I believe you are correct!
TXRed- Thank you for chiming in. I know your knowledge on this particular issue is extensive…
Gregg- They aren’t the only ones. Dammit…
