The Ogallala aquifer underlies 41 counties in the Texas Panhandle, and is the principal source of water in that area. Unfortunately, the aquifer has very low recharge rates, maybe 1 inch per year, vastly exceeded by pumpage rates. As a result, the Ogallala has seen average declines of 1 foot per year in Texas. In fact, in some parts of the Panhandle, drawdown of the aquifer has ranged as high as 8 feet per year, and cumulatively, historic watertable declines of 150 feet have been registered.
Andy Wilkinson sings about the “Sandstone Champagne”, the precious waters from the Ogallala aquifer.
