drought

In the summer of 2002, water pumps in Colorado’s San Luis Valley stopped working.

The center pivot sprinklers that coax shoots from the dry soil and turn the valley into one of the state’s most productive agricultural regions strained so hard to pull water from an underground aquifer that they created sunken pits around them.

“This one right over here,” says potato farmer Doug Messick as he walks toward a sprinkler, near the town of Center. He's the farm manager for the valley's Spud Grower Farms. “I came up to it one day and I could’ve driven my pickup in that hole.”
