SAN FRANCISCO (AP) - San Francisco officials have approved a plan that would greatly complicate future efforts to drain a city-owned flooded gorge in Yosemite National Park that has been called a twin of breathtaking Yosemite Valley.
The San Jose Mercury News reports (http://bit.ly/XzWQ0O) that the San Francisco Public Utilities Commission on Tuesday voted 5-0 for port the plan.
The Hetch Hetchy reservoir in Yosemite is the main source of water for 2.5 million Bay Area residents.
But the system serves 1.7 million people outside the city, so Michael Carlin, deputy general manager of the commission, said it is only fair they have a voice in any changes.
Environmental groups said they may sue to overturn the rule, arguing that San Francisco owns the reservoir so should be solely responsible for it.
