Most ponds in southern Louisiana are excavated. That part of the world is flat. It's a common practice to excavate an area, to find dirt to create building pads and road beds. Plus, it rains a lot in south Louisiana...and if it freezes in winter, it's reported on the television news as an event.
So, six feet is plenty deep in that part of the world. With a productive enough well, and 360+ days above freezing, this pond will be fairly easy to manage, as long as there is very little area less than three feet deep. With little or no flushing, fertilization will be effective in promoting plankton and minimizing rooted aquatic plants. Fish production will be enticing, because this pond is a focal point, easily accessible, with a readily available water supply in case of management miscues. It sounds as close to "perfect" as a scenario can be in that part of the world.
