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.
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).

An aquifer is a geologic formation, a group of formations, or a part of a formation that contains sufficient saturated permeable material to yield significant quantities of water to groundwater wells and springs.
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.
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 or High Plains Aquifer sits under 450,000 km 2 of 8 states of the United States of America. It is one of the largest freshwater deposits in the world. The aquifer is composed of unconsolidated alluvial deposits. Groundwater in this aquifer has been dated to have been deposited in the humid time following the last glacial maximum. [8]
The water in the Ogallala Aquifer is worth billions to western Kansas, but it’s disappearing. It's been a challenge to find ways to slow depletion. Ogallala Aquifer dropped 12+ inches in 2021.
