Hey, woodbutcher, welcome to Pond Boss! Glad you're here! I love it - a mud bog in your back yard! I'm wondering how many times someone has shouted, "Hold my beer and watch this!" (Not that we EVER hear that sort of thing in West By God Virginia!)
Sounds like you've got a good spot for a pond and it's absolutely great that you found the forum before you got started on it. If you take your time and read all you can, ask questions, and maybe pick up a couple of books that are available here on the site, you'll likely save yourself a ton of headaches and heartaches brought on by mistakes.
You may want to start a new thread under the Pond Construction section of the forum as it will likely get more looks by forum members. Also, check out the Books page of the site
here and give serious consideration to purchasing "Perfect Pond...Want One?" and "Basic Pond Management, The Manual." Those and the other books have tons of great info and could be a huge help for you as you plan and start to execute on the project.
Stick around, let us know how things are progressing and keep posting pics of your progress!
