Welcome to the forum, and the family you will love this place.

Worked in the panhandle a long time ago. Never even saw any clay, the whole time I was there, good for you. There was a high water table. That makes much of a pond hard to do. It looks like you hit a home run.

You have more than likely done this, but be sure the area that was disturbed by the dirt guy has grass on it. A good cover will help the erosion �the water clarity and make the pond much friendlier to the family.
