This comprehensive and detailed work is the major documentation in support of the proposal to dam the Hetch Hetchy Valley in Yosemite National Park, ostensibly to meet the water supply needs of San Francisco and its growing population. San Francisco's "need" to gain the rights to the Hetch Hetchy Valley provoked a seven-year environmental struggle with the Sierra Club, led by the environmentalist John Muir. Eventually, passage of the Raker Act permitted flooding of the Valley and construction of the dam was finished in 1923. The reservoir now supplies water to 2.4 million Californians in San Francisco, San Mateo, and Alameda counties as well as some communities in the San Joaquin Valley. [Rocq: 9436]..
