The Ogallala Aquifer (oh-gə-LAH-lə) is a shallow water table aquifer surrounded by sand, silt, clay, and gravel located beneath the Great Plains in the United States. As one of the world's largest aquifers, it underlies an area of approximately 174,000 sq mi (450,000 km 2) in portions of eight states (South Dakota, Nebraska, Wyoming, Colorado, Kansas, Oklahoma, New Mexico, and Texas).

The Ogallala Aquifer was formed more than 25,000 years ago, but it recharges at a very low rate. For years, irrigators in Kansas have drained more from the aquifer than rainfall can replace.
Ogallala Aquifer of the central United States is one of the world's great aquifers, but in places it is being rapidly depleted by growing municipal use, and continuing agricultural use. This huge aquifer, which underlies portions of eight states, contains primarily fossil water from the time of the last glaciation. Annual recharge, in the more ...
The Ogallala aquifer is the principal source of water for agriculture in western Kansas. It’s not an underground lake as some believe but saturated sediments that have been deposited over the ...
The Ogallala Formation is a Miocene to early Pliocene geologic formation in the central High Plains of the western United States and the location of the Ogallala Aquifer. [1] In Nebraska and South Dakota it is also classified as the Ogallala Group . [ 2 ]
Water levels in the Ogallala Aquifer continue to plummet as farm irrigation swallows an average of more than 2 billion gallons of groundwater per day statewide.
A critical water source could soon go dry.
The Ogallala aquifer, or the High Plains aquifer, is an integral fresh water source for the entirety of the Great Plains region, providing drinking water to 80% of the population and irrigating 13 million acres of land. Precipitation, seasonal lakes, and prehistoric water reserves serve as sources of water for the aquifer, which lies beneath ...
