Grass is not an option in Salton City, which survives on water pumped in from the Colorado River. With 20 million more residents expected in California by 2050, the quest for water is never over.

The exhibition is based on “Water: Our Thirsty World,” the current issue of National Geographic. Read more about the photography in the issue and exhibition in PDN’s April Exposures feature here.
