Thanks for the replies guys, both bodies of water are in fact on private property. As ive never dove in, aside from the occassional swim or two I dont know exactly what the visibility would be like much deeper than that.
But id guess it wouldnt be terrible, its not crystal clear but not impossible to see through either. I would love to go diving in some of those lakes/rivers with submerged buildings.
Another quick question, as I havent done any diving in a number of years and im sure I would have to get re certed. Is that a PITA, or is it relatively painless?
I think ill hold off on doing any diving in the lakes here for now, however if anyone finds themselves this way it should definately be considered.

Maybe we wont find a dragon, but who knows..We may find my old wedding ring I lost down there years ago.

Good fishing anyway, largest bass ive caught thus far was an eight pounder. Folks around this area im sure are aware of the much larger, lake Meredith. That would likely be a more eventful dive, as its rumored some murder victims may have been disposed of there (and who knows what else.)
