A vivid account of America’s first environmental cause célèbre, which illuminates our attitudes toward fundamental questions of growth, development, and our place in nature.

The building of the O’Shaughnessy Dam and Hetch Hetchy Reservoir in the middle of Yosemite National Park–despite the availability of less expensive, less technically challenging, and less politically complicated possibilities–set off a defining controversy in American environmentalism. From the early 1900s to 1913 Americans argued about proposals to dam the Tuolumne River and transform the extraordinary Hetch Hetchy Valley into a giant source of water and hydroelectric power for the San Francisco Bay Area. It is a story of intrigue replete with political scandals and suspect tactics played out in the corridors of Congress, in San Francisco’s City Hall and its corporate boardrooms, and in the national media. The colorful cast of characters includes Theodore Roosevelt, Gifford Pinchot, and John Muir, as well as a host of political bosses, West Coast boosters, East Coast patricians and publishers, big-business interests, newly formed environmental groups, and the American public.

Simpson also takes us through the building of the enormous dam and the extensive tunnels and aqueducts that carry water to the Bay Area, and the even more controversial hydroelectric project that still fails to deliver the “public” power that Congress mandated and about which the U.S. Supreme Court ruled. He recounts conversations with an array of people currently involved in the ongoing controversy over whether to manage, refurbish, repair, and enlarge the system, or to tear down the dam and restore the valley to its prior splendor. Simpson concludes with a reflection on what all of this reveals about American attitudes toward growth, development, and environmental stewardship.
