What ever ya do is between you and your pop. I usually pop off before I know exactly what's goin on.
Depending on what acreage is needed for the horses your pop could possibly build a small pond. When a pond is excavated there is a bunch of dirt to be removed. It is often used in constructing a dam. A sloping ground would be benifical to the pond if located at the lowest level.
Again, I'm not an expert.
