Book excerpt: The American West, blessed with an abundance of earth and sky but cursed with a scarcity of life's most fundamental need, has long dreamed of harnessing all its rivers to produce unlimited wealth and power. In Rivers of Empire, award-winning historian Donald Worster tells the story of this dream and its outcome. He shows how, beginning in the mid-nineteenth century, Mormons were the first attempting to make that dream a reality, damming and diverting rivers to irrigate their land. He follows this intriguing history through the 1930s, when the federal government built hundreds of dams on every major western river, thereby laying the foundation for the cities and farms, money and power of today's West. Yet while these cities have become paradigms of modern American urban centers, and the farms successful high-tech enterprises, Worster reminds us that the costs have been extremely high. Along with the wealth has come massive ecological damage, a redistribution of power to bureaucratic and economic elites, and a class conflict still on the upswing. As a result, the future of this "hydraulic West" is increasingly uncertain, as water continues to be a scarce resource, inadequate to the demand, and declining in quality.
