The Hetch Hetchy project had its beginning in early 1900s when the City and County of San Francisco gained generous rights to the Tuolumne River watershed in 1910. The project centered on damming the main Tuolumne River as it meandered through Hetch Hetchy, a wide glacial-cut valley almost as grand as Yosemite. The river, with its source in a perpetual glacier on 13,000-foot-high Mount Lyell, drains 650 square miles of watershed in rugged granite mountains sloping west from the Sierra Nevada crest. The Hetch Hetchy water system design had an ultimate goal of providing 400 million gallons of water per day to San Francisco and the growing Bay Region. John Muir fought for environmental protection and led the Sierra Club in a campaign to protect the Hetch Hetchy Valley, a part of Yosemite National Park, from being filled with a reservoir. This battle was one of the first grassroots lobbying efforts, getting citizens to contact elected officials. Despite opposition, the Raker Act of 1913 was passed by the U. S. Congress and signed by President Woodrow. In February 1916, the Hetch Hetchy rail line began as a connection of the Sierra Railway at Hetch Hetchy Junction, fifteen miles west of Jamestown and extended another sixty-eight miles to the O'Shaughnessy Dam site for delivery of materials. The vast undertaking created miles of tunnels and a 150-mile aqueduct to deliver the water and electricity to the Bay Area. Of the many dams, reservoirs, and power plants, three were in the high country of Tuolumne County. The main and largest, O'Shaughnessy Dam. The main dam was built in two phases. Large pipes called penstocks channeled water down the mountain to the main Moccasin Power Plant completed in 1925. It was 1934, when the first Hetch Hetchy water was delivered to the Bay Area.

A superb summary with great pics of the building of Hetch-hetchy dam and railroad and water system to the city. A must buy if you have been to camp Mather.Note this is later edition--maybe the printing of pics is better?
