Less is more, in my book. Recommendation is to not exceed 10-20% of pond with structure. Remember vegetation will comprise a lot of structure, too. Whatever structure I add I use to try and provide focus points that collect fish and try to make it snagless, too. Access casting from shore or dock is important to remember, also if you ice fish some in deeper water is a good focal point in the Winter. Considering how much PVC you have I'd stick with it and bypass the maples, metal racks, poles, and fencing. That's just my personal preference.

You may want to research how to construct SMB spawning beds to encourage recruitment. I posted my design on clay bottom ponds that works very well, but there's probably many variations that would work. Pallets will come in handy for the SMB beds.

Many men go fishing all of their lives without knowing that it is not fish they are after. ~ Henry David Thoreau
