Take a browse through the structure section and you will glean enough info to take care of your needs. One thing I found was that I placed the structure too far from the water line. It looked good when I placed it, but as the pond continued to fill the distance between the water line and the structure increased dramatically. The other thing that I found important for me was hiding the structure. I had a visitor with a cast net and he/she removed about 30 fair sized tilapia and would have possibly gotten more except he/she got hung up in the structure. I used a system that golf courses use for yard markers and just point out the markers to my guests. Might not work for you but, I don't live at my pond just yet.
