Hey East Texas,
First, welcome to the forum. I'm a relative newcomer (6 months or so) myself.
Your place sounds very similar to mine. I've been working on putting a pond in since January, and between weather, contractors, test holes, new contractors, etc. I've yet to get it built.
I will caution you, however, to dig a deeper test hole. We found layers of sand in mine, which would definitely not hold water, and have since redesigned the thing to plate over the sandy layers. If I'd just dug the thing it would fill up during the wet months, and drain bone dry in the summer. Spend $150 bucks for someone with a backhoe to come in and dig some test holes for you. Also, contact the NRCS for some free advice.
