The Ogallala aquifer (pronounced OH-GA-LA-LA) is one of the largest aquifer systems in the world. It stretches across all or portions of eight states generally from north to south to include South Dakota, Nebraska, Wyoming, Colorado, Kansas, Oklahoma, New Mexico, and Texas and underlies about 174,000 square miles. N.H. Darton is credited with describing and naming the formation in 1899 after the town of Ogallala, Nebraska.
The Ogallala aquifer lies relatively near the land surface in most of the above-described area with a maximum thickness of about 1,000 feet with a few hundred feet more the norm. Even in those areas of only a few feet of thickness, the aquifer can almost always be counted on to yield water to a well drilled into it. Some wells yield only a few gallons of water per minute, while others yield 1,000 gallons of water per minute or more.
