Hetch Hetchy And Its Dam Railroad

Hetch Hetchy: Its Origin and History by Michael Maurice O'Shaughnessy, first published in 1934, is a rare manuscript, the original residing in one of the great libraries of the world. This book is a reproduction of that original, which has been scanned and cleaned by state-of-the-art publishing tools for better readability and enhanced appreciation. Restoration Editors' mission is to bring long out of print manuscripts back to life. Some smudges, annotations or unclear text may still exist, due to permanent damage to the original work.

In the wake of the devastating 1906 earthquake and fire, the city of San Francisco desperately needed reliable supplies of water and electricity. Its mayor, James Phelan, pressed for the damming of the Tuolumne River in the newly created Yosemite National Park, setting off a firestorm of protest. For the first time in American history, a significant national opposition arose to defend and preserve nature, led by John Muir and the Sierra Club, who sought to protect what they believed was the right of all Americans to experience natural beauty, particularly the magnificent mountains of the Yosemite region. Yet the defenders of the valley, while opposing the creation of a dam and reservoir, did not intend for it to be maintained as wilderness. Instead they advocated a different kind of development--the building of roads, hotels, and an infrastructure to support recreational tourism. Using articles, pamphlets, and broadsides, they successfully whipped up public opinion against the dam. Letters from individuals began to pour into Congress by the thousands, and major newspapers published editorials condemning the dam. The fight went to the floor of Congress, where politicians debated the value of scenery and the costs of western development. Ultimately, passage of the passage of the Raker Act in 1913 by Congress granted San Francisco the right to flood the Hetch Hetchy Valley. A decade later the O'Shaughnessy Dam, the second largest civil engineering project of its day after the Panama Canal, was completed. Yet conflict continued over the ownership of the watershed and the profits derived from hydroelectrocity. To this day the reservoir provides San Francisco with a pure and reliable source of drinking water and an important source of power. Although the Sierra Club lost this battle, the controversy stirred the public into action on behalf of national parks. Future debates over dams and restoration clearly demonstrated the burgeoning strength of grassroots environmentalism. In a narrative peopled by politicians and business leaders, engineers and laborers, preservationists and ordinary citizens, Robert W. Righter tells the epic story of the first major environmental battle of the twentieth century, which reverberates to this day.

In 1913, President Woodrow Wilson signed legislation approving the construction of the O’Shaughnessy Dam to inundate the Hetch Hetchy Valley inside Yosemite National Park. This decision concluded a decade-long, highly contentious debate over the dam-and-reservoir complex to supply water to post-earthquake San Francisco, a battle that was dramatic, unsettling, and consequential. Hetch Hetchy: A History in Documents captures the tensions animating the long-running controversy and places them in their historical context. Key to understanding the debate is the prior and violent dispossession of Indigenous Nations from the valley they had stewarded for thousands of years. Their removal by the mid-nineteenth century enabled white elite tourism to take over, setting the stage for the subsequent debate for and against the dam in the early twentieth century. That debate contained a Faustian bargain: to secure an essential water supply for San Francisco meant the destruction of the valley that John Muir and others praised so highly. This contentious situation continues to reverberate, as interest groups now battle over whether to tear down the dam and restore the valley. Hetch Hetchy remains a dramatic flashpoint in American environmental culture.

Chronological history of water use in San Francisco and the city's battle to win control of the Hetch Hetchy Valley, and design, fund, and build the dam and aqueduct

When water from the Sierra Nevada reached the San Francisco Bay area in 1934, it was greeted by a national celebration after two decades of grueling construction. The Hetch Hetchy Project evolved from a long search for a reliable source of water for San Francisco that began after the 1906 Great Earthquake. Prior to the earthquake, San Francisco had burned to the ground repeatedly due to the lack of water to fight fires. Studies of 14 different sources led to the design of an engineering marvel that conveys water using gravity across California via a complex system of tunnels, reservoirs, pipelines, powerhouses, treatment plants, and dams. But before the Hetch Hetchy Project broke ground, controversy roiled over the project. Finally, the Raker Act was passed by Congress in 1913 and signed by Pres. Woodrow Wilson to permit the use of the rights-of-way for the project. Today, this system serves some of the highest-quality water in the nation to 2.4 million people.
