Martin Samuel Vilas, Water and power for San Francisco from Hetch-Hetchy Valley in Yosemite National Park (1915)
“ San Francisco may obtain this water, as good as any in the world, and sufficient for her thousands to come for the next 100 years. She may thereby obtain such water power as during the same time will cause all the wheels of industry on her great Bay to whirl and to whirr. Yet the Yosemite National Park in the entire and Hetch-Hetchy in particular will remain, visited by more than ever before, a thing of beauty and a joy unto the ages yet to be.—San Francisco Chronicle, Jan. ”
