Another lake drained

Local residents astonished that desert basin is desert basin.

The few who live along the shores of Mono Lake are accustomed to the peculiarities of this high desert basin.

Famously strange limestone spires known as tufa towers rise from the water. The lake contains so much salt that it’s barren of fish. In the arid sands beyond, sagebrush thrives, and that’s about it.

But the alkali flats that are emerging from the lake’s surface, ghost white, aren’t just another nod to the uniqueness of this ancient place. They’re a sign of trouble. Amid a third year of drought, the sprawling lake on the remote east side of the Sierra Nevada is sharply receding, and the small towns and wildlife so closely tied to the water are feeling the pinch.

Drought? Drought??? Who could possibly have seen that coming?

The drought bearing down on Mono Lake and the rest of California picks up on a two-decade run of extreme warming and drying. It’s a product of the changing climate that has begun to profoundly reshape the landscape of the West and how people live within it. From less alpine snow and emptying reservoirs to parched forests and increased wildfire, the change is posing new, and often difficult, challenges.

Now why would reservoirs be emptying just because the planet is heating and people keep building new houses in deserts? I just can’t figure it out, can anyone?

For eight decades, the city of Los Angeles has piped water from four creeks that feed the lake to its facilities 350 miles to the south, sometimes diverting almost all of the inflow. It’s a familiar California tale of old water rights yielding inordinate benefit.

“Excuse us, we need this water for our city 350 miles from here, thanks, bye.”

The concerns at the lake, though, were supposed to have been resolved. In 1994, after a lengthy environmental campaign that spurred “Save Mono Lake” bumper stickers on vehicles up and down California, state water regulators put caps on L.A.’s exports. Slowly, lake levels rose. But they did not rise as much as they were supposed to.

Scold them. Tell them they’re not living up to their part of the bargain. Remind them it’s a signed agreement.

Drought, on top of a climate that’s changed faster than expected, has slowed progress. On April 1, the typical start of the lake’s runoff season, the water level measured 6,379.9 feet above sea level, about 12 feet short of the state target. Before Los Angeles began drawing water from the creeks here, the lake was nearly 40 feet higher.

Who knew that if you use something up then it’s gone?
