THE SIGHT OF FOUNTAINS, swimming pools — As drought and climate change tighten their grip on the American West, the sight of fountains, swimming pools, gardens and golf courses in cities like Phoenix, Las Vegas, Los Angeles, Salt Lake City, Boise, and Albuquerque can be jarring at first glance.

Western water experts, however, say they aren’t necessarily cause for concern. Over the past three decades, major Western cities — particularly in California and Nevada — have diversified their water sources, boosted local supplies through infrastructure investments and conservation, and use water more efficiently.

Peter Gleick, president emeritus of the Pacific Institute, has studied water resources for decades. He calls the reduction in per capita water use a “remarkable story” and one that’s not widely acknowledged.

“That’s a huge success throughout the West,” Gleick said. “All of the cities in the West have made progress.”

But with less water flowing into the Colorado River, which serves 40 million people in the West and northern Mexico, experts say the measures taken by cities will still not be enough long-term.

Here's a look at how Western cities have prepared for a future with less water.
