like Rainman said buy those books. one thing is I would see if they will build you some bottom contours , points etc. the ones I have seen in Ok. have been rectangle holes with smooth same depth bottom. in saying that if I could get a pond dug for free I would pay for rocks, put in wood structure etc.. I will tell you have FOUND THE RIGHT SITE. These guys know there stuff. Get Pond boss Mag. too.
Like a lot of people I wish I had found this site earlier.
