Muir's personal experiences in Yosemite were crucial to his environmentalist defence of Hetch Hetchy Valley
in the face of the O'Shaughnessy Dam project, which was given the go-ahead in late 1913.
The fight to save Hetch Hetchy Valley
in Yosemite National Park and prevent the building of the O'Shaughnessy Dam was led by John Muir and the Sierra Club.
The flooding of the Hetch Hetchy Valley
, a national treasure nearly as remarkable as Yosemite Valley, is documented in this survey of the political, engineering and natural history challenges the project brought.
He worked with the city fathers of San Francisco to take Yosemite's identical twin, Hetch Hetchy Valley
, and dam it to create an emergency supply of water should an earthquake of such magnitude ever hit the city again.
John Muir called it "one of Nature's rarest and most precious temples." California's Hetch Hetchy Valley
was at one time as sublime as nearby Yosemite Valley.

Struggle was signified through the illness and loss of family and friends, but much more by the protracted battle for the Hetch Hetchy Valley
. For more than a decade Muir and the membership of the Sierra Club argued passionately for conserving this unique catchment, but in August 1913 the resistance was finally overpowered by the State's developmentalist demands for a significant water reservoir to supply San Francisco.
But the effort had started several years earlier, when Horace McFarland, president of the American Civic Association, sparked a movement to establish a parks agency after he and naturalist John Muir had failed to save the Hetch Hetchy Valley
, part of Yosemite that was dammed in 1913.
This is not a new phenomenon, in 1906 John Muir protested in vain against the construction of a dam across the Hetch Hetchy Valley
in Yosemite National Park to supply water for San Francisco.
Here in Sacramento, my colleagues on the editorial pages have vigorously advocated lower bus fares for schoolkids, for better zoning decisions, for restoring the Hetch Hetchy Valley
, for better schools, for honest government.
He failed to secure the beautiful Hetch Hetchy Valley
inside Yosemite National Park, which was eventually flooded to provide water and hydroelectric power for San Francisco.
On the one hand, the governor, building off a Pulitzer Prize-winning editorial series in the Sacramento Bee and an Environmental Defense Fund report, Paradise Regained, unexpectedly commissioned a state study in 2005 to investigate the feasibility of removing the long-controversial O'Shaughnessy Dam in Yosemite National Park's Hetch Hetchy Valley
. That study even more remarkably motivated a sympathetic response from President George W.
