A ballot proposal that would have led to the dismantling of O’Shaughnessy Dam and drained Hetch Hetcy valley has been defeated by San Francisco voters.
CBS News: With all precincts reporting, unofficial election results showed that 77 percent of San Francisco voters voted no on Proposition F, a measure put on the ballot by a group seeking to restore the valley to its natural state.
The measure would have forced the city to formulate a plan to dismantle the dam, constructed in 1923, and improve local water conservation efforts. The plan would have gone before San Francisco voters as a charter amendment in November 2016.
