The West, more than any other American region, was built by state power, state expertise, state technology, and state bureaucracy. That is another way of saying that it has been, and is, the most thoroughly modern of American regions, and therefore that its experience, particularly in the matter of water, has been most instructive for deciphering the confused messages of that modernity.
By positioning water as technology rather than nature and the West as a federally-funded, man-made landscape, Worster both deconstructs the West's self-image as independent and free of government control AND reconstructs the region not as a colony of the East but as the seat of a global American empire.
For Worster, the American West is a "modern hydraulic society," a "social order based on the intensive, large-scale manipulation of water and its products in an arid setting." Versus Thoreau's vision of a Western society based on free, self-defining individuals and egalitarian community organization, the West as hydraulic society is "coercive, monolithic, and hierarchical," run by the elite owners of capital and business. In addition to a sharply divided class structure, the West also has a sharp division between technology and nature, as evinced in the irrigation canal, whose smooth, abstract flow is fenced off from animals, humans, and life in general, while the communities that surround it are in comparative disarray. Worster traces the development of this "techno-economic" landscape by first contextualizing it among other hydraulic societies, where elites used irrigation and flood control to control the social order, and then tracing the 150 year intensification of water control in the American West through 3 phases:
- Incipience (Mormon migration in 1847 to 1890s): dependence on local skills and means, isolated communities and limited of small rivers, failed attempts by private corporations to harness rivers
- Florescence (1902, when the Federal government took control of Western rivers via the National Reclamation Act, to WWII): Federal government provides capital and engineering expertise to "lift the region to a higher plateau of development;" corporations and quasi-corporations finally succeed in farming rivers for profit; a sharply divided class structure develops
- Empire (1940s to the present): government and private wealth form a powerful alliance and bring every major river under their unified control; goal is to create an unparalleled hydraulic society.
Capitalism was critical to the development of the West because it moved rivers from a riparian system with usufruct rights (only people who live along a river can lay claim to it) to a system of prior appropriation (whoever gets to a river first can have it, even if s/he doesn't own property along it). It also rewarded destruction of some landscapes and relocation of some people to harness water for others - a remarkably anti-democratic project in the name of democracy. Further, because water in the arid West was scarce, social power was tied to toil and large capital investments, which some saw as rugged individualism but Worster sees as American empire: absolute domination of nature by elites who spout individualism but take money from the Federal government to support their power.
By constructing the West as a "hydraulic society" and an American empire, Worster successfully demythologizes the West. He also makes me never want to live much further west of the Mississippi than I already do, even if LA is the center of a global cultural and economic empire, because that empire is based on total technological domination of nature.
