In the quiet northern reaches of Yosemite National Park lies a wound we’ve never fully healed from—a twin to the famous Yosemite Valley, once filled with waterfalls, meadows, and birdsong. Today, it lies drowned beneath 300 feet of water.

Hetch Hetchy, as it’s called, was once one of the most breathtaking natural cathedrals in the Sierra Nevada. To legendary naturalist John Muir, it was a place “as beautiful as Yosemite,” an untouched wonder shaped by glaciers and time.

And yet, despite its sacredness and location within a national park, it was dammed and flooded to create a reservoir for San Francisco in the early 20th century. That loss wasn’t just ecological or aesthetic—it was philosophical.

Hetch Hetchy was the first major battle over what our public lands, particularly national parks, are for. And we lost.

The story of Hetch Hetchy isn’t just history. It’s prophecy.

Because today, over a century later, the same logic that drowned Hetch Hetchy is once again threatening America’s public lands: the belief that the “greater good” justifies sacrificing our natural heritage—that convenience, consumption, and economic expedience are more important than wildness, beauty, or legacy.

Hetch Hetchy Valley once rivaled Yosemite Valley in terms of scenic beauty and wildlife. Now, the Tuolumne River is dammed and this once-breathtaking valley is under 300 feet of water. (NPS)

A Park in Name, Not Protection

Let’s be clear: Hetch Hetchy was inside Yosemite National Park when it was dammed.

The idea that a city could waltz into a federally protected landscape and flood it sounds unthinkable today—or at least, it should.
