The Pacific Institute reports that California's farmers could save nearly 6 million acre-feet of water in a normal year. In today's San Francisco Chronicle , reporter Kelly Zito notes that is enough water to fill Hetch Hetchy Reservoir 16 times.
Even if the potential savings is an overestimate, it is pretty clear that restoration of Hetch Hetchy Valley in Yosemite National Park is achieveable. Restoration would require, however, a level of cooperation between San Francisco, its urban customers and other water interests that we have not seen to date.
Let's work together to ensure that farms and cities use water as productively as possible, and make possible restoration of Hetch Hetchy and other precious ecosystems.
