The severe depletion of the Ogallala Aquifer is symptomatic of a larger crisis in the United States and many parts of the world. Much more water is being pumped from the ground than can be naturally replenished, and groundwater levels are plummeting. It’s happening not only in the High Plains and drought-ravaged California but also in places from the Gulf Coastal Plain to the farmland of the Mississippi River Valley, and from the dry Southwest to the green Southeast.
In a nationwide examination of the problem, USA TODAY and The Desert Sun analyzed two decades of measurements from more than 32,000 wells and found water levels falling in nearly two-thirds of those wells, with heavy pumping causing major declines in many areas. The analysis of U.S. Geological Survey data revealed that:

In a nationwide examination of the problem, USA TODAY and The Desert Sun analyzed two decades of measurements from more than 32,000 wells and found water levels falling in nearly two-thirds of those wells, with heavy pumping causing major declines in many areas. The analysis of U.S. Geological Survey data revealed that:
- Nationwide, water levels have declined in 64 percent of the wells included in the government database during the past two decades.
- The average decline among decreasing wells has been more than 10 feet, and in some areas the water table has dropped more than 100 feet during that period – more than 5 feet per year.
- For 13 counties in Texas, New Mexico, Mississippi, Kansas and Iowa, average water levels have decreased more than 40 feet since 1995.
- Nationally, the average declines have been larger from 2011-2014 as drought has intensified in the West. But water tables have been falling consistently over the years through both wet and dry periods, and also in relatively wet states such as Florida and Maryland.
- Across the High Plains, one of the country’s largest depletion zones, the average water levels in more than 4,000 wells are 13.2 feet lower today than they were in 1995. In the southern High Plains, water levels have plunged significantly more – in places over 100 feet in just 20 years.
