I suspect two dynamic forces are at play that nullify the theory of a rising water table. The first is that while the trees held a lot of water, they also eliminated wind and sunlight at ground level. With the trees gone, the evaporative effects of sun and water cause an equilibrium in water retention. The second only applies to land that is graded, but because pockets are eliminated to make the field smooth; water moves across the land unlike it used to when it was a forest.
