The Hetch Hetchy reservoir was created a century ago to supply fresh water for millions of people in the Bay Area. It was created by damming the  Tuolumne River, flooding  a former mountain valley in the Sierras and forming a reservoir that can hold up to 117 billion gallons of water. Hetch Hetchy embodies a feat of modern engineering, but as the globe warms up and demand for water shifts, the reservoir’s storage capacity and water management capabilities may not hold up. For our next installment of Climate Fix: Rethinking Solutions for California, we’ll talk about how climate change is putting pressure on Hetch Hetchy and what a far warmer future means for this mountain bathtub.
