Ogallala Blue: Water and Life on the Great Plains

by William Ashworth

Overview

A story of a crucial, dwindling natural resource: an invisible ocean of fresh water under the High Plains.

The Ogallala Aquifer that lies deep beneath the Great Plains from Texas to Colorado contains enough water to fill Lake Erie nine times! Every year five trillion gallons are pumped out for irrigation, and if (or when) the aquifer goes dry, $20 billion worth of food and fiber grown with that irrigation will disappear. William Ashforth tells the fascinating history of the Ogallala from its formation millions of years ago to glimpses of the future when the Great Plains could return to their Sahara Desert-like past.

Editorial Reviews

People of the Great Plains have been drawing on the underground water of the sprawling Ogallala Aquifer for centuries. But it took a failed tinkerer's single inspired invention in 1948-the center-pivot sprinkler system-to precipitate this century's looming crisis over access to potable water, on land stretching from South Dakota to Texas and from Colorado almost to Iowa. The sprinkler (followed by ever more sophisticated water extraction systems) sprayed water across fields of corn and cotton more efficiently, reports Ashworth (The Late, Great Lakes). But this in turn led to an increase in land under cultivation-a situation that, compounded by suburban sprawl in the southwest, means that for the past half-century, water that had collected below the surface over many millennia is now being consumed far more quickly than nature can replenish it. Ashworth recounts some conservation efforts that could achieve a "tenuous balance" between supply and demand, but he doesn't hold out much hope that years of rampant mining of the aquifer's once-vast liquid resources can be reversed. Firsthand vignettes about efforts to introduce dryland farming techniques and reintroduce buffalo herds add some zip to the narrative, but for a doomsday book about a dire situation, the text is often pretty dry.
