I got board and started thinking of and sketching some ideas, sorry for the crappy sketches didn't feel like putting in a lot of detail. Please Note that the depths are ideal for my area, it will vary in different parts of the US.
Ditch Structure: allows the bank fishermen more opportunities in the hot summer months and the cold winter months. This also allows the bass to spawn/feed in the shallows and retreat to the deep. I wouldn't put all the trees, brush, rock etc so close together or you will lose every bait you own, its just to give you an idea.
Well Structure: Ideal for the center, most ponds are devoid of Structure in the middle, others build submerged Islands. This gives the fish more ambush and hiding places with varied deaths. The 2nd is for easy entry but also creates more ambush points.
Flooded Timber: A lot of ponds in this area have to be dug out, this leaves little room for standing timer to be flooded. Simply dig holes and place cut down trees in, fill and pack. Imo an island should be added as well.
