If I remember correctly, years ago (probably 25 or more) there was some sort of green metal pipe about halfway out in Sugar. There's all sorts of junk out there from before the lake was formed and construction items from the building. Also lots of stuff that braniacs thought would be a good idea to stick in the lake for one purpose or another... like the metal culverts sticking out of the sand bar down near Pine Bluff. Buried years ago by a duck hunter to use as a blind (except they stay flooded because there's no bottom to them) but now they like to collect unsuspecting props and lower units at summer pool.
