The Ogallala Aquifer has a visibility problem. It’s easy to see when drought, farm irrigation and city taps drain the great reservoirs of the Southwest. Bathtub rings paint the red rock walls surrounding Lake Powell as it shrinks, sounding alarm bells loud and clear. What about a body of water that’s locked away in a subterranean labyrinth of gravel and rock reaching more than 300 feet underground? The Ogallala may hold as much water as Lake Huron, but we can’t see it. And, problematically, that means we can’t see it disappear.
