Iffen you go up 6 Mile Creek there are the remains of an old dariy milking parlor that can be found. The milking stanchions are still in place and there are the remnants of an old rock out-building not far away - looks like an old butter house or something like that.
But, for the most part, what mofo said is pretty much on target. Every now and then you can find some old brick, dang I forget the name, things that houses are set upon.
There was one structure that was made of rock, a house, that when the lake was impounded was not moved, if my investigations are correct. I've never been able to put it to a plat or plot to determine any GPS coordinates - if I could that would be a GREAT dive.
Anyway, make your own adventures in our cold and murky pond . . .
And by the way, WELCOME!!!! to ScubaBoard.
