BBM: Quit using those big words.....DEBRIS! Debris, yes I get it. Just had never heard of flotsam and jetsam. Thanks for explaining! And yes a body can get caught up in that flotsam and jetsam pretty darn easily. So one cannot assume if a body went in anywhere in that lake that the current would always carry it down to the dam.

ETA: No, unless you know the topography(is it topography in a lake?) of the lake, you cannot assume it would make it to the dam. That might be the direction a piece of wood floating on the surface would go, but not necessarily anything under water. My experience, only.
