The Mojave desert in the southwest of the United States is the driest region in North America. Despite the scarity of water, a big city thrives here. With its elaborate fountains and more than 50 golf courses, Las Vegas is synonymous with extravagance even when it comes to water. Here the precious resource comes almost entirely from the Colorado river. It flows down from the rocky mountains into lake mead. A huge man made resevoir behind the hoover dam.
