My wife and I spent years going over our pond shape. This was a 7 year plan with the pond and house. We chose a kidney shape with two deep holes in each end of the kidney with a ridge in the middle. The position was to the large open side of the kidney faces our prevailing winds. This was to get the most wave action.
With the two deep ends aeration was easy with two air stations and two more in the shallows. The shallow ridge is where we are working on planting lily pads and water plants. The west/north sides are where we place the branches for the perch to spawn on. They seam to like this side of the pond I expect because of the sun getting this area most of the day.
