HAHAHA! NO! Those circles are fields. Have you never heard of a center pivot irrigation system?
Here's the basic gist - there is a well drilled in the center of the field and on that well is a water pump. As water is pumped through the center pipe of the span, the whole system walks around the center pivot in a circle to irrigate the crops - typically corn, because corn takes A LOT of water.
You see a LOT of them out west.
Flying over the area is like flying over a polka dot quilt.
