Pond Boss Forums POND CONSTRUCTION Creating habitat Advice on Placement of Cover/Structure

Thanks to everyone for helping. But how about my original question, regarding the 3' or so tall dirt mount shelf that I have built that will be in about 5' of water. Regardless of what cover materials that I use (trees, artificial), should I put that cover on top of the shelf? Beside the shelf? Or some one way and some the other?

Thanks!
