Las Vegas Running Out of Water Means Dimming Los Angeles Lights

Feb. 26 (Bloomberg) — On a cloudless December day in the Nevada desert, workers in white hard hats descend into a 30- foot-wide shaft next to Lake Mead.

As they’ve been doing since June, they’ll blast and dig straight down into the limestone surrounding the reservoir that supplies 90 percent of Las Vegas’s water. In September, when they hit 600 feet, they’ll turn and burrow for 3 miles, laying a new pipe as they go.

The crew is in a hurry. They’re battling the worst 10-year drought in recorded history along the Colorado River, which feeds the 110-mile-long reservoir. Since 1999, Lake Mead has dropped about 1 percent a year. By 2012, the lake’s surface could fall below the existing pipe that delivers 40 percent of the city’s water.

As Las Vegas’s economy worsens, the workers are also racing against a recession that threatens the ability to sell $500 million in bonds so they can complete the job.

Patricia Mulroy, manager of the Southern Nevada Water Authority, is the general in this region’s war to stem a water emergency that’s playing out worldwide. It’s the biggest battle of her 31-year career.

‘We’ve Tried Everything’

“We’ve tried everything,” says Mulroy, 56, who made no secret of her desire to become secretary of the U.S. Interior Department before President Barack Obama picked U.S. Senator Ken Salazar of Colorado in December.

“The way you look at water has to fundamentally change,” adds Mulroy, who, after 20 years of running the authority, said in January she’s ready to start thinking about looking for a new job, declining to say where.

Across the planet, people like Mulroy are struggling to solve the next global crisis.
