The Edwards Aquifer is located in south-central Texas, primarily under the San Antonio region, while the Ogallala Aquifer is located in the Great Plains region of the United States, extending from South Dakota to Texas. The Ogallala Aquifer is geographically north of the Edwards Aquifer.
Ogallala.
One can find information about Ogallala aquifer on various websites like HPWD and Geography. Both websites offer a great amount of information about all kinds of products including the Ogallala aquifer.
The Ogallala Aquifer recharges slowly because the overlying soil and vegetation limit the amount of rainfall and snowmelt that can infiltrate into the aquifer. Additionally, the aquifer's large size and depth also contribute to the slow rate of recharge.
The Ogallala aquifer is the most heavily used.
The Great Plains region of the United States benefits from the underground water of the Ogallala Aquifer. This region includes parts of eight states: South Dakota, Nebraska, Wyoming, Colorado, Kansas, Oklahoma, New Mexico, and Texas. Agriculture in this region heavily relies on the water from the Ogallala Aquifer for irrigation.
Some of the largest aquifers in the US include the Ogallala Aquifer, the Edwards-Trinity Aquifer System, the Floridan Aquifer System, and the Great Basin Aquifer System. These aquifers are crucial sources of groundwater for drinking water and irrigation in their respective regions.
I believe you are looking for the Ogallala Aquifer.
The Ogallala Aquifer is one of the world's largest aquifers, spanning across eight U.S. states and covering approximately 174,000 square miles. It provides water for agriculture, municipal, and industrial uses in the region.

The Ogallala Aquifer is considered a non-renewable water source because its recharge rate is much slower than the rate at which water is withdrawn from it. Once the water is depleted, it will take thousands of years to replenish naturally. It is crucial to manage water use from the Ogallala Aquifer sustainably to ensure its long-term availability.
The High Plains are underlain by an enormous aquifer, the Ogallala Aquifer, which consists of thick sands and gravels running in a great north-south belt from Wyoming and South Dakota, through the sand hills of Nebraska, along the eastern border of Colorado and the western half of Kansas, through the panhandle of Oklahoma to northwest Texas.
