Hetch Hetchy is a valley, a reservoir, and a water system in California in the United States. The glacial Hetch Hetchy Valley lies in the northwestern part of Yosemite National Par k and is drained by the Tuolumne River. Hidden in Yosemite National Park’s peaceful northwest corner, Hetch Hetchy Valley is a treasure worth visiting in all seasons. Located at 3,900 feet, Hetch Hetchy boasts one of the longest hiking seasons in the park and is an ideal place for thundering spring waterfalls and wildflower displays. High temperatures prevail in summer months, but that is a small price to pay for the reward of vast wilderness filled with stunning peaks, hidden canyons, and remote lakes.Hetch Hetchy is on the main stem of the Tuolumne River and is part of the Tuolumne watershed. The Tuolumne River originates in the peaks above Tuolumne Meadows and is the major drainage system for the northern part of Yosemite. The Tuolumne River continues through Tuolumne Meadows and the associated park developments at an elevation of 8,600 feet. It then cascades on its westward descent through the Grand Canyon of the Tuolumne, and enters the eastern end of Hetch Hetchy Reservoir. Hetch Hetchy is dammed by the 430-foot-tall O’Shaughnessy Dam and has a storage capacity of 360,360 acre-feet. It is the primary water source for about 2.5 million residents of the San Francisco Bay Area.
