Water and power for San Francisco from Hetch-Hetchy Valley in Yosemite National Park

"Water and power for San Francisco from Hetch-Hetchy Valley in Yosemite National Park" by Martin S. Vilas is a historical record from the early 1900s that tells the story of how San Francisco worked to get water and power from the Hetch-Hetchy Valley. The book explains the political battles, especially around the Raker Bill in 1913, and the engineering plans to build a dam and manage resources, all to meet the needs of the growing city. Vilas describes the Hetch-Hetchy Valley, explaining why it was a great place to get water and power for the San Francisco Bay Area. While acknowledging concerns about protecting Yosemite National Park, he argues this project would improve both access and conservation in the long run.
