Owens Valley Salty As Los Angeles Water Battle Flows Into Court Almost 100 years ago, a water-supply diversion from Owens River helped quench Los Angeles' thirst some 200 miles away. L.A. thrived, but it drained the Owens Lake and created a salt flat that now pollutes the air. A century later, the finger-pointing continues, and this week, the city's water department is back in court over its cleanup plan.

It's ALL THINGS CONSIDERED from NPR News. I'm Audie Cornish.

In the West, fights about water can last a long time. It's been almost a hundred years since Los Angeles began piping water from the Owens Valley, about 200 miles away. That water allowed L.A. to become the metropolis it is today. It also means that Owens Lake turned into a massive dusty landscape. It became the source of the worst particulate air pollution in the country. Now, Los Angeles is back in court facing the question of whether it's done enough to control that pollution.

NPR's Kirk Siegler takes us to Owens Lake.


KIRK SIEGLER, BYLINE: At the end of a bumpy road skirting the barren edge of the dry Owens Lake bed, highway signs tell you all you need to know about this environment. That way to Furnace Creek, straight ahead to Stove Pipe Road, then Death Valley beyond. The wind has left small sand dunes on the road. Even in winter, the high desert sun is punishing but you can see for miles.


SIEGLER: And it's not hard to spot the white speck of Marty Adams' helicopter coming into view on the southern horizon.


SIEGLER: We're four hours away from L.A. unless you have a chopper, the journey takes about an hour and a half.

MARTY ADAMS: You must be Kirk.


ADAMS: Hi, I'm Marty.

SIEGLER: Marty Adams is what you'd expect of a higher up in a powerful, water agency in the West. Friendly, polished, he's given this aerial tour of Owens Lake hundreds of times.

ADAMS: So it's on the eastern Sierra, the eastern side of the Sierra Nevada. And we're actually kind of in the shadow of Mount Whitney.

SIEGLER: The highest peak in the Lower 48. Adams is director of water operations for L.A.'s Department of Water and Power. So he oversees the complex system that collects snow melt off those towering mountains and carries it all the way to the taps in the country's second largest city. But he's also in charge of dealing with the environmental consequences of all of this - and they're huge.

ADAMS: So, people hear a dry lake and you might think it's a mountain lake, it's surrounded by trees. And, you know, we're talking a salt flat is what this essentially is. It's like any kind of...

SIEGLER: A salt flat the size of San Francisco, and when the wind blows can churn up some huge dust storms with extraordinarily high levels of particulates that are dangerous to breathe. That helped earn Owens Lake the dubious mark of being the largest single source of dust pollution in the nation. And California law leaves no ambiguity for who the responsible polluter is.

In the late 1990s, the city of L.A. reached an historic deal and agreed to a clean-up plan. To date, they've spent more than a billion dollars doing that, giving this place another distinction: One of the largest dust control projects in U.S. history.

ADAMS: And it's really trying to control dust in a desert that's naturally dusty.

SIEGLER: Those dust control measures are easier to see once the chopper climbs higher. There are a few places where bulldozers have laid gravel but it's mostly just giant, shallow pools of water. It's still the weapon of choice to fight dust. And Adams says, each day, the city pumps enough of it back on to the dry lake to fill the Rose Bowl. So his agency has gone to federal court to make the case that they're done here.

ADAMS: We believe that we've done everything we've committed to do. At this point, we believe the job is done.

SIEGLER: Not so fast, say California air quality regulators. Ted Schade is in charge of monitoring air pollution in this area. He says the city is almost done with the clean up, 90 percent of the plan in fact has been met, and 45 square miles are controlled. So why stop now?

TED SCHADE: The reason the city is not deploying additional controls - the additional controls that are required to meet the standard - is simply about money.

SIEGLER: When Schade took the job in 1990, the levels of particulate coming off Owens Lake during storms were 100 times the standard the federal government says is safe to breathe. These tiny particulates are especially nasty because they're hard to detect and can build up in the lungs over time and cause respiratory problems. Schade says things have gotten a lot better around the dry lake bed. But...

SCHADE: The fact that we're measuring dust levels 10 times higher than the standard, where no other desert areas in the West are seeing levels that high, so something is still wrong. It may have been a dusty place but it wasn't this dusty.

SIEGLER: The Owens Valley was a dusty place even before L.A.'s water diversions began. It's also a vast, sparsely populated place. But people here still have to live with the dust. And some still complain of allergies and other respiratory problems when the storms blow in and choke the valley.

MEL JOSEPH, LONE PINE PAIUTE SHOSHONE TRIBE: So this is our met tower. And then we have our Q air monitors up here.

SIEGLER: On a dirt road tucked off Highway 395, Mel Joseph climbs a ladder to the top of an air quality control monitor that he operates for the Lone Pine Paiute Shoshone Tribe. These days, Joseph says there are a lot fewer stage one air alerts, but they still happen.

TRIBE: You know, it's an environmental justice issue as well for us, as to why our reservation is located five miles from the nation's largest source of particulate pollution.

SIEGLER: And there's no doubt in Mel Joseph's mind that the city of L.A. is still to blame for that pollution. Up and down this rural valley, there's been no love lost for the city's Department of Water and Power since it began diverting water here 100 years ago.

TRIBE: It's a desert climate but they made it the dust bowl that it is today.

SIEGLER: And so this tale ends where so many other battles over water in the arid West do - the courts. They'll decide whether Los Angeles has done enough to control that dust bowl or whether they'll have to spend millions of dollars more to finish the job.
