The Ogallala Aquifer stretches from Texas to South Dakota.
- It originally contained as much water as a Great Lake and in the late1970's provided one fifth of all the irrigation water in the US
- Estimates indicate that this aquifer will be effectively "dry" by 2030(less than 100 years after pumping began).
Globally, there is a 160 billion cubic meter overdraft of groundwater peryear
