Hetch Hetchy Reservoir

Hetch Hetchy Reservoir Review

When Congress approved the O'Shaughnessy Dam in 1913, pragmatism triumphed over aestheticism. Some 2.4 million residents of the San Francisco Bay Area continue to get their water from this 117-billion-gallon reservoir, and spirited efforts are being made to restore the Hetch Hetchy Valley to its former, pristine glory. Eight miles long, the reservoir is Yosemite's largest body of water, and one that can be seen up close from several trails.
