reviews Reviews Silenced Rivers: The Ecology and Politics of Large Dams, by Patrick McCully. Zed Books, London & New Jersey, 1996, xv+350 pp., $24.95 paper. In December, 1945, then Governor Earl Warren convened a "California Water Conference" to discuss the California Water Plan. As he neared the end of his opening address he said "...in my opinion we should not relax until California has adopted and put into operation a state-wide program that will put every drop of water to work." The Governor was probably unaware that he was repeating Josef Stalin's dictum that "Not a drop of water must escape to the sea." Obviously, it did not occur to either leader that the water in rivers was working and that excessive diversion would have profound consequences. Patrick McCully has done an impressive job gathering the information contained in Silenced Rivers, and it is no criticism of the book to point out how little has changed with our bankers and engineers and politicians since 1984, when Edward Goldsmith and Nicholas Hildyard published The Social and Environmental Effects of Large Dams. In many ways Silenced Rivers takes over where the previous book left off. Both books provide compelling evidence that the construction of large dams results in more ecological damage than they are worth, and that nearly all dams cost much more than estimated. Construction of dams in unsuitable and dangerous locations continues to be the rule rather than the exception, and banks continue to obligingly provide the unanticipated overruns. I began my professional career in 1938 as part of the crew assembled to study what could be salvaged of the fish populations of the Sacramento River threatened by the construction of Shasta Dam. At that time nobody knew--and few cared--how many fish would be lost. On the basis of counts during the irrigation season, when a diversion dam was installed, at least 27,000 fish passed through the counting weir at Redding. This suggested a potential production of 94,500,000 eggs! Unfortunately, our study was not even begun until the keyways for the dam had already been dug and concrete was being poured. There was no possibility of salvaging these runs and there were no suitable, accessible streams or equipment to handle the fish. The last great tributary above the dam site was the McCloud, whose headwaters included a vast stream of icy water flowing out of the lava from Mount Shasta's bygone activity. We of that last research crew witnessed the passing of the last salmon of the McCloud. As we were prepared to leave the river, we were informed about the plan to dam the Trinity River and divert its water through a tunnel to the Sacramento River. The dam was completed in 1952. Another great salmon river was destroyed. In many parts of the world, unidentified or unknown fishes are endangered by dams; there are probably hundreds of undescribed species in the streams and lakes of Africa, Indonesia, and the Philippines for instance. Many of them support the natives along the rivers, whose environments will disappear when some ruler decides he needs electric light in his palace, and whose delusions of grandeur have been nourished by unscrupulous investors from distant climes. One of the most disturbing results of all this dam building has been the removal or "resettlement" of native people. Since figures are not known in each case, no effort has been made to suggest the total number of people displaced by dams. But a tally of available figures suggests that the recently started Three Gorges Dam in China may displace more people than all other dam projects combined. McCulley's chapters grind on and on with such titles as "Rivers No More," "When Things Fall Apart," "Paradise Lost," and "Temples of Doom." They are introduced by some fatuous quotation from a dignitary or a bit of verse more or less appropriate to what follows. Evidently he could not find any suitable place for Algeron Swinburne's "even the weariest river winds somewhere safe to sea." Perhaps because there is too little left even to be weary after the dam makers get through. Nor does he quote Kenneth E. Boulding's "A Ballad of Ecological Awareness": There are benefits, of course,
which may be countable, but which But "ecological truth" does not seem to be in the vocabularies of California water users. Indeed, it is unsettling to consider how little progress has been made in the past half century. (Who reads these books except the converted, anyhow?) It is a slow movement toward the sensible approach, toward a reverence for rivers and a due appreciation for the role they play in our natural systems. Recomended
Reading This wide-eyed, courageous, and intelligent investigation of the 1980 Mount St. Helens eruption and its aftereffects is a fugue of science reporting, nature writing, and personal history. Colasurdo describes the pre-eruption mountain, and the happy years she and her family spent there, as Edenlike. And the eruption--which blew 1,300 feet off the mountain, completely rearranged its topography and watercourses, and mowed down its forests--is a powerful metaphor for innocence lost. Science, introspection, and a lot of walking reveal to Colasurdo the healing consolation of insight and maturity even in what first appears to be complete devastation; where once a dark and robust forest grew now the only living thing was a species of carnivorous beetle living off the insect carcasses blown to the pumice plain by the wind. No, you can never go home again. Yes, in each end there is a beginning. And, above all, geology is great. A Natural History of the Monterey Bay National Marine Sanctuary. Published by the Monterey Bay Aquarium and the National Oceanic and Atmospheric Administration, 1997, 260 pp., $19.95 paper. Californians love their coast, and they campaigned long and hard for a national marine sanctuary with Monterey Bay as its center. Finally designated in 1992, the nation's largest marine sanctuary stretches 53 miles offshore and encompasses one fifth of the state's coastline from north of the Golden Gate to Cambria. This comprehensive guidebook homes in from the big-picture oceanography and geology to consider in detail several specific habitats: sloughs and sand dunes, the intertidal shore and the sandy seafloor, even wharf pilings and shipwrecks. Each chapter includes a selected species list for a habitat; the sanctuary's total species tally includes 26 marine mammals, 94 seabirds, 345 fish, and 450 marine algae. The wealth of invertebrates fills 31 phyla. Black-and-white photos and illustrations depict many plants and animals. Numerous sidebars explore such topics as warring sea anemones, seasonal change in the kelp forests, and bioluminescence. The book is printed on heavy paper stock, as though to encourage your tossing it in a backpack before heading out to kayak Elkhorn Slough, or watch sea otters at Point Lobos. Natural State: A Literary Anthology of California Nature Writing, edited by Steven Gilbar. University of California Press, Berkeley, 1998, 381 pp., $45.00 cloth, $15.95 paper. Reading this diverse collection of nature writing will not qualify you for a "been there, done that" attitude toward California's literature of the wild. Anthologies are topographical, revealing the locations of their subject's heights and depths, but not dedicating the pages to attain them.That's why they can be so much fun, but ultimately so unsatisfying. At least 36 of the 39 authors in Natural State deserve to be relished, like the sunrise in Ann Zwinger's essay about Yosemite Valley: "I enjoy the earth's staging time, getting everything adjusted, ordered, before turning on the sun." Jumping in and out of Joaquin Miller (or John Daniel, or Mary Austin) is like jumping in and out of a desert hot spring: complete submersion and thorough soaking under the stars are not incidental to the experience. Despite its limits, any collage made out of such worthy scraps as this is bound to be an interesting read in its own right. This one certainly is. Natural State is broken into seven sections. The first, and sadly the shortest, contains two Native American creation stories. The following four sections divide the state into mountains, hills and valleys, the desert, and the coast. Section six is about weather and geology. For the most part the writers are found where you'd expect them--Mary Austin, and Ed Abbey in the desert, John Muir and Mark Twain in the mountains--but there are some surprises. |
