But in 1913, the U.S. Congress authorized the city of San Francisco to construct a dam and reservoir on the Tuolumne River in Hetch Hetchy to ensure that San Francisco would have a dependable water supply. It is said that the act broke John Muir’s heart, and some have even suggested that this great sadness hastened his death in 1914. By 1923, the dam was completed and the valley was flooded under several hundred feet of water.
Today, the Hetch Hetchy Valley, like many of America’s natural landscapes, is at the center of a restoration debate. But is trying to turn back the clock on natural areas we altered long ago the best way to spend environmental funds, especially in these cash-strapped times? Or would working to protect those wild places we still have in their original state be a better use of scant resources?
