The Ogallala Aquifer: Charting the Waters of the Texas High Plains

- This video outlines the challenges posed by the depletion of the Ogallala Aquifer in the Texas High Plains, highlighting the overuse of this vital water source for irrigation and its rapid decline. It also emphasizes the need for sustainable water management practices to preserve the aquifer for future agricultural use, discussing the historical context and the aquifer's critical role in supporting the region's agriculture.
The Ogallala Aquifer is a massive underground, freshwater reservoir that extends across eight states from South Dakota to Texas. Critical for large-scale production agriculture, nowhere is the aquifer more in danger of running dry than in the Texas High Plains.
Lucia Barbato of the Texas Tech University Center for Geospatial Technology explains the Ogallala Aquifer using sophisticated maps of the region. This underground water supply is critical for irrigation tor area farmers and it’s a finite freshwater resource that’s running dry. This is an extended interview from the 30 minute documentary we filmed in 2010 about the efforts of area stakeholders, producers (farmers), scientists, universities and state and federal government agencies, to more accurately measure water usage and find ways to extend the life of aquifer for agricultural purposes.

Partial Transcript:
This is a challenging land. It always has. It is today. The challenge is that while we are over at the southern end of the aquifer that's a virtually finite water supply. Because of the ability to tap that resource and use it for irrigation. A lot of it's already been used, it's a very rapid rate. We use it far in excess of it’s ability to recharge. And today we're dependent on that for agriculture as we know it. But that's changing, that change has got to come as rapidly as the decline, because we've got to learn other ways of keeping this land productive.
The Ogallala Aquifer extends all the way up into South Dakota, Nebraska, Kansas, and they have a lot more water in some areas than we do here in West Texas, the Ogallala Aquifer in the southern part of Texas is cut off by the, the, the area over here that's been drained and eroded. And over here by the Pecos River. So really this is the only extent, that, that, that's left. So, we're not getting recharged anymore from the Rocky Mountains...

Great presentation! Ended with hope and not despair.
That was super interesting, and elegantly presented. Thanks for uploading!
Wonderful video and resource! Thank you.

That brings down my anxiety about lubbock being swallowed up in a sink hole
There are areas and times when the groundwater was near the surface. Before the Canadian Rivers formation drained the Central Panhandle. These are early multiple deposits at a single location made by many porous stream beds separating the silts and sometimes mostly sands. Materials were brought from higher elevations to the Mid American Sea 30 to 60 million years ago. When looking for places to drill wells I have often seen evidence in sample materials of flowing in many thin stream beds in general directions from the West. Often just moving several hundred feet the multiple formation samples will be totally different. The water in this formation is from local rainfall east of the Pecos river watershed that varied over millions of years. The water has been replaced thousands of times as it is drained by river channels to the east.
I'm looking for land in the Lubbock area right now. I'd like to graze goats and chicken. I don't even know where to begin. The water situation is constantly rearing its head in my search.
hope the area doesn't turn into a dust bowl again
Desalination from ocean water is the answer.
