Las Vegas is a fantastical Disneyland for adults in the middle of the desert. It features fabulous displays of water — like the thousand dancing fountains of the Bellagio Hotel or the winding canals that recreate Venice at the Venetian Hotel. But surprisingly, it’s a city that has also become known for water conservation and innovation.

In this episode, we sit down with Pat Mulroy, who was the top water manager in Southern Nevada for 25 years and led conservation efforts in the desert city. We talk with her about the existential crisis that Las Vegas and other desert cities face, how Southern Nevada has been able to cut its Colorado River water use by 31% in the past two decades, and what that means for the trade-offs that we all may have to consider to keep living where we want to live.
