If San Francisco voters pass Measure F on November 6, the city will conduct an $8 million study on the feasibility, costs, and benefits of draining the 300-foot deep reservoir created by the O’Shaughnessy Dam in 1923. The measure’s proponents see it as a first step in restoring Hetch Hetchy Valley, sister valley to Yosemite, to its natural state. That the measure is even on the ballot is a significant indication of the shift in attitudes towards the ongoing conflict between nature preservation and traditional notions of progress.
