Most Colorado cities and farms get water from snowmelt in the Rockies. That’s not the case in Northeastern Colorado. This food-producing powerhouse depends on an ancient, underground reservoir called the Ogallala.
Ever since the Ice Ages, the Ogallala’s been slowly accumulating water. Modern farmers, though, pump so much water that this “timeless” aquifer is starting to run out. Someday up ahead, Northeast Colorado may have to curtail some crops, and some farm towns might become ghost towns.
