The book reviewed by Rebecca Solnit is "Dead Pool: Lake Powell, Global Warming and the Future of Water in the West" by James Lawrence Powell (California, 2010):
The supply of stories has perhaps been the American West's only reliable bounty. The difficult thing has been finding people to notice them, let alone tell them well. The Indian wars, still unfinished as tribes continue to struggle for rights, territory and cultural survival; the resource rushes, the Gold Rush in particular, which turned San Francisco into a cosmopolitan city standing alone in the wilderness; the once astonishingly abundant salmon runs that sustained soil and trees, as well as birds, bears and humans; the timber wars; the range land wars; the radical labor and environmental movements; the attitudes people adopted towards a harsh, unfamiliar, often sublime landscape; the evolution of European cultures in a non-European terrain and the arrival of Asian and Latin American immigrants to shape a hybrid culture: all these have had their occasional historians, though most Americans were raised to believe that history happened somewhere else. The San Francisco Public Library has an overflowing case of books on the East's Civil War, but only a handful on the war that transferred a million square miles or so of Mexico to the United States, including California and most of what we now call the West.

Of the rise of the modern environmental movement; the evolution of ideas about landscape, aesthetics, the public good and the battles between a boom-town, resource-rush mentality and a minority more interested in long-term planning. And it's the story of the rise of the big cities of the South-West, notably Phoenix and Las Vegas, whose optimism is inscribed in their names (the immortal bird whose name will surely become ironic during the course of this century; the vegases, or meadows, watered by an aquifer that Vegas sucked dry early in its short history). And of the City of Angels, whose situation is not quite as precarious as that of the desert towns, but whose thirst has long outstripped its regional resources and reached the Colorado River, far to its east.
T.S. Eliot's Mississippi was a "strong brown god': the Colorado River is more like a ruddy writhing serpent. Or was, since the snake has now been chopped into segments by dams, notably by Glen Canyon Dam above the Grand Canyon, and Hoover Dam south of Vegas, each with a gigantic reservoir backed up behind them. Even its red colour, its Colorado, has changed; the sandstone sediment settles behind Glen Canyon Dam and what was once a hot red river emerges as a cool green one, too cool for many of its species of endangered fish. Occasionally a thunderstorm over a tributary sends down enough sediment to turn it red again for a day or two.
No one holds a monopoly, but Americans have proved very good at junk science. It's a speciality field, in which the claims about Iraq's weapons of mass destruction, aluminium "centrifuge' tubes and the like, are only the most widely noted. The Panglossian "rain follows the plough' was the motto used to dispatch hapless would-be farmers to the arid lands of the American West, where rainfall is inadequate to raise crops and irrigation started as a corruption racket and ended up as an environmental disaster. Its agenda is short-term convenience. Its methodology is lies. An atmospheric scientist once told me that he had checked Edward Teller's projections of the amount of fallout that would reach Americans during the years of above-ground nuclear testing in southern Nevada. The great genius had somehow left off some zeros, reducing the impact a hundred or a thousandfold, while other scientists created arbitrary standards of exposure safety and schoolchildren were taught to duck and cover to protect themselves from atomic blasts. Scientific facts about the environment water flow, radioactive half-lives, principles of containment etc were jiggled until they could be used to justify the dumping of nuclear waste near the atomic test site.
Junk science might be too generous a label for the way conclusions have been reached about the water of the Colorado River: how much there is and how much and how securely it can change the arid landscape around it. The water has transformed that landscape. Without it, Arizona and southern Nevada would still be barely populated and a lot of the agriculture in the South-West wouldn't exist. But the supply was always precarious and overcommitted, and it is already running out. Water limitations were noticed from the beginning, when Major John Wesley Powell and his crew became the first white men to float down the Colorado. Powell's 1875 Exploration of the Colorado River and Its Canyons, an expansion of his magazine reports, is still in print. It is a gorgeous book about adventure, geology, anthropology and hydrology, with illustrations carrying captions like "The Great Unconformity at the Head of the Grand Canyon' and chapters such as "From Flaming Gorge to the Gate of Lodore'. But it was the sobering A Report on the Lands of the Arid Region of the United States, with a More Detailed Account of the Lands of Utah of 1878 that makes Powell matter even today. A Civil War veteran and government explorer, he saw that there wasn't enough water to irrigate people's visions of a big agricultural society and that the limits on water would ultimately be the limit on everything else. Ignoring Powell has been the basis of almost everything that has come since, except the literature on the river, which Powell presides over as a kind of god.
James Lawrence Powell's Dead Pool tells the story of the Colorado well and moves it forwards to speculate on what the era of climate change will bring. He isn't optimistic: in his account climate change is just one more factor that the engineers and hydrologists responsible for plotting the river's fate refuse to face. He begins with two crises at Glen Canyon Dam: one of a sudden abundance of water that nearly destroyed the dam in the 1980s, another when the water level fell, in 2005, lower than the official scientists had calculated it would ever go. (A disaster for water managers, it was a miracle for explorers, who got to see canyons and cliff faces that were thought to have been lost for ever.) Dead Pool then doubles back to begin the story at the beginning, with Major Powell and his warnings on the finitude of the South-West's water.
To a man of Powell's principles and background, that his nation encouraged thousands of poor farmers to move to lands so dry that the settlers were bound to fail was a tragedy. He would spend most of the rest of his career trying to save them from that fate " By March 1888 one of Powell's scientific facts was undeniable: the West had too little water to irrigate all the land. To collect and best use what water did exist would require a system of dams and reservoirs.
Building those dams and reservoirs would, in theory, be a co-operative enterprise; in practice it was a big-government project for the benefit of Westerners who for the most part considered themselves individualists and independents. This delusion of self-sufficiency, along with the fantasy that enough water could be found to supply the region, launched the eco-tragedy now unfolding.
Towards the end of his book, Powell points out that the US Bureau of Reclamation has decided not to take climate change into account when planning water management and allocation for the 21st century. Instead, it has been basing its projections on what we now know was the unusually wet 20th century. No shortage, no problems to plan for. Powell points out that climate change is not something that may happen to the American West or that is now happening only in the Arctic. It is here, now. And at the end of Dead Pool he describes what a post-climate-change South-West might look like the book's title, incidentally, is the term used to describe a reservoir when its water level drops too low to feed the intake valves for hydropower generators.
The Salton Sea is already a conundrum, a toxic bird sanctuary in a place where water doesn't belong, and the reservoir-dam systems will go the same way. But not all the strange phenomena that have arisen from the long wrestling match with the Colorado are situated near it. Take the San Francisco-based, family-owned Bechtel Corporation, which is to the United States what the Bin Laden construction firm is to Saudi Arabia, a colossus itself and a maker of colossi. Bechtel emerged from the building of the Hoover Dam to become a major force in reshaping the West and then the world: it is responsible for nuclear power plants and infrastructure for mining in hitherto roadless jungle and for triggering Bolivia's water war earlier this decade when its attempts to privatise Cochabamba's water backfired; it was one of the more visibly problematic contractors in Bush's Iraq. (The Bin Laden family was earlier this decade a "substantial investor', with $10 million in a private equity fund owned by Bechtel, but that's another story.)
No one opposed the Hoover Dam, built at the height of the Depression and of hope in technology, but Glen Canyon Dam, built 30 years later, was controversial from the outset. The Sierra Club's fury at the development transformed it from a genteel regional mountaineering society into the most powerful environmental group in the country. The canyon that would be dammed was one of the most beautiful places in the South-West, as the Sierra Club knew when it originally signed off on it as a replacement for a dam upstream, then changed its mind and began to fight in vain, ultimately to save the canyon and the river ecology downstream. Yet the struggle produced the soul-searching and rabble-rousing out of which came the modern environmental movement. The logic for the dam was hard to find, but the junk science basic errors concerning the rate of evaporation (creating a big lake in a desert entails giving a lot of the water to the sky), squirrelly figures about costs, the amount of water the river collects annually was not. Powell concludes that the dam and Lake Powell exist because a powerful Colorado representative wanted them and because the Bureau of Reclamation "needed new dams to burnish its reputation and justify its funding and staff levels'.
