The Southwest Is Running Dry. Here's How Las Vegas Beat It.

The Southwest Is Running Dry. Here's How Las Vegas Beat It. Lake Mead, the largest reservoir in the United States, has lost about 160 feet of water since the year 2000 and now sits near a third of its capacity. The lake is not coming back. But one city on its shoreline quietly did what no other did. This is how Las Vegas cut its water use, recycled almost everything it touched, and spent more than a billion dollars to survive a lake falling toward dead pool, while the rest of the Southwest kept arguing. Inside this video: how Hoover Dam built the modern Southwest during the Great Depression, the 1922 agreement that promised more water than the river ever carried, the megadrought driving the collapse, and the engineering that keeps one desert city alive as the water disappears around it. The honest part matters. Las Vegas saved Las Vegas. It did not save the Colorado River. That distinction is the whole story.
