Las Vegas Running Out of Water Means Dimming Los Angeles Lights

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.

From 2500 B.C., when King Urlama of Lagash diverted water in the Tigris and Euphrates Valley in a border dispute with nearby Umma, to 1924, when Owens Valley, California, farmers blew up part of the aqueduct that served a parched Los Angeles, societies have bargained, fought and rearranged geographies to get the water they need.

Mulroy started her push with conservation. She’s paying homeowners $1.50 a square foot (0.09 square meter) to replace lawns with gravel and asking golf courses to dig up turf. That helped cut Las Vegas’s water use by 19.4 percent in the seven years ended in 2008, even as the metropolitan area added 482,000 people, bringing the total to 2 million. It wasn’t enough.

Paul Bunyan

So she’s planning a $3.5 billion, 327-mile (525-kilometer) underground pipeline to tap aquifers beneath cattle-raising valleys northeast of the city. She’s even suggested refashioning the plumbing of the entire continent, Paul Bunyan style, by diverting floodwaters from the Mississippi River west toward the Rocky Mountains.

If Mulroy’s ideas are extreme, one reason is that the planet’s most essential resource doesn’t work like other commodities.

There’s no global marketplace for water. Deals for property, wells and water rights, such as the ones Mulroy must negotiate to build the pipeline, are done piecemeal. As the world grows needier, neither governments nor companies nor investors have figured out an effective and sustainable response.

“We have 19th-century ways of utilizing water and 21st- century needs,” says Brad Udall, director of Western Water Assessment at the University of Colorado at Boulder.

Unyielding Pressure

Water upheavals are intensifying because the population is growing fastest in places where fresh water is either scarce or polluted. Dry areas are becoming drier and wet areas wetter as the oceans and atmosphere warm. Economic roadblocks, such as the global credit crunch and its effects on Mulroy’s attempts to sell bonds, multiply during a recession.

Yet local governments that control water face unyielding pressure from constituents to keep the price low, regardless of cost. Agricultural interests, commercial developers and the housing industry clash over dwindling supplies. Companies, burdened by slowing profits, will be forced to move from dry areas such as the American Southwest, Udall says.

“Water is going to be more important than oil in the next 20 years,” says Dipak Jain, dean of the Kellogg School of Management at Northwestern University in Evanston, Illinois, who studies why corporations locate where they do.

No Cheap Water

Even before the now decade-long drought began punishing Las Vegas, people used more than 75 percent of the water in northern Africa and western Asia that they could get their hands on in 2000, according to the United Nations.

In 2002, 8 percent of the world suffered chronic shortages. By 2050, 40 percent of the projected world population, or about 4 billion people, will lack adequate water as entire regions turn dry, the UN predicts.

“We can no longer assume that cheap water is available,” says Peter Gleick, editor of The World’s Water 2008-2009 (Island Press, 2009). “We have to start living within our means.”

Over the Sierra Mountains from Las Vegas, Shasta Lake, California’s biggest reservoir, is less than a third full because melting snow that fed it for six decades is dwindling. A winter as dry as the previous two may mean rationing for 18 million people in Southern California this year, says Jeffrey Kightlinger, general manager of the Metropolitan Water District.

Across the Pacific Ocean, wildfires fueled by a 10-year drought and fanned by 60-mile-per-hour winds around Melbourne killed more than 200 people in February.
