What a beautiful place, Lee. Judging from the trees, your soil must be a bit alkaline. Were you losing water into a limestone formation? I am originally from down-river (Vicksburg) and the less hilly parts of the surrounding county look a lot like your land. I have sometimes wondered if ponds in relatively alkaline soil ever need buffering with lime. Does anyone here have experience with that situation?

Also, have you considered planting cypress trees in the shallow end of the pond? They sure are pretty this time of year.
