Almost 100 years ago, Congress approved a dam and reservoir in Yosemite to supply water and power to San Francisco. The project flooded the scenic Hetch Hetchy Valley. Now environmentalists want to drain the reservoir, hoping to restore what they call "a second Yosemite Valley." Under Measure F, the city would spend $8 million to develop an alternative plan for its water and power. But critics say the measure squanders taxpayer money and could jeopardize the city's water supply. Should we restore Hetch Hetchy?
