In 1913, President Woodrow Wilson signed legislation approving the construction of the OâShaughnessy Dam to inundate the Hetch Hetchy Valley inside Yosemite National Park. This decision concluded a decade-long, highly contentious debate over the dam-and-reservoir complex to supply water to post-earthquake San Francisco, a battle that was dramatic, unsettling, and consequential.\n\nHetch Hetchy: A History in Documents captures the tensions animating the long-running controversy and places them in their historical context. Key to understanding the debate is the prior and violent dispossession of Indigenous Nations from the valley they had stewarded for thousands of years. Their removal by the mid-nineteenth century enabled white elite tourism to take over, setting the stage for the subsequent debate for and against the dam in the early twentieth century. That debate contained a Faustian bargain: to secure an essential water supply for San Francisco meant the destruction of the valley that John Muir and others praised so highly. This contentious situation continues to reverberate, as interest groups now battle over whether to tear down the dam and restore the valley. Hetch Hetchy remains a dramatic flashpoint in American environmental culture.
