Draining the Ogallala

The Ogallala Aquifer is a giant body of water that sits hundreds of metres below the great plains in the USA. It extends from North Dakota all the way south to Texas, and it estimated to contain a volume of water greater than that of all the Great Lakes combined.

The Aquifer is the primary source of irrigation and water usage for agriculture in the US, as 1/5 off all agricultural water is withdrawn from this source.

The problem is that the water is being withdrawn at a much faster rate than it is being replaced. (Partly) As a result of this, Canada and US water relations have developed a more business-like aspect.

If you have the time or the inclination, these two links - while long - are excellent summaries on the issue.
