The Salton Sea, an Accident of History, Faces a New Water Crisis

The vast California lake relies on runoff from cropland to avoid disappearing. But as farmers face water cuts due to drought and an ever drier Colorado River, the Salton Sea stands to lose again.

The Salton Sea, an Accident of History, Faces a New Water Crisis

BRAWLEY, Calif. — The drought crisis on the Colorado River looms large in California’s Imperial Valley, which produces much of the nation’s lettuce, broccoli and other crops, and now faces water cuts. But those cuts will also be bad news for the environmental and ecological disaster unfolding just to the north, at the shallow, shimmering and long-suffering Salton Sea.

“There’s going to be collateral damage everywhere,” said Frank Ruiz, a program director with California Audubon.

To irrigate their fields, the valley’s farmers rely completely on Colorado River water, which arrives by an 80-mile-long canal. And the Salton Sea, the state’s largest lake, relies on water draining from those fields to stay full.

But it’s been shrinking for decades, killing off fish species that attract migratory birds and exposing lake bed that generates dust that is harmful to human health. As the sea has receded, it’s also left abandoned houses, shuttered resorts and landlocked marinas that, in the mid-20th century, had transformed the area into a fishing and water-sports playground for Southern Californians.

Now, with cuts in water use coming after two decades of drought that have left the Colorado’s reservoirs at dangerously low levels, the sea will shrink even faster. “Less water coming to the farmers, less water coming into the Salton Sea,” Mr. Ruiz said. “That’s just the pure math.”
