Take a look here, Gracie,
http://en.wikipedia.org/wiki/Sink_hole
We are sitting on limestone deposits here. As the ground water recedes it leaves space for surface water to seep down into the vacant space. Heavy rains cause the ponds to fill to the point where the pressure causes the seep to get more aggressive and large enough to empty the pond while washing dirt out with it. Like pulling the plug in a bath tub.
