If you don't aerate the pond the water deeper than 7-8ft will not have any oxygen in the summer during thermal stratification. I would put the structures less than 8 ft deep. If you ice fish, the fish will usually be in the deepest area. Structures there in deep areas will likely be places for fish to wrap your line around and you will loose the fish. In a small pond like this I would put all structure in one or two spots to act as fish attractor and refuge area. Refuge area for fish should be fairly shallow and alone one whole side of the pond abt 20-30% of the shoreline. Deeper structures are essentially ambush point for the predators. The pond is small so the fish can't go very far so locating them should not be too difficult. Creating hook smart fish in a small pond, that is whole separate topic.
