Bobad,
Have you had a problem with drift due to wave action? Do the stick up beyond the surface.

I have most of the stickups in 6-7' of water, and they are only about 2.5' long. It's possible that counter current on the bottom could move them, but I seriously doubt it. I think if they are sufficiently under the surface, wave action won't move them. Having just gone through 2 hurricanes, all bets are off. There isn't much that 80mph winds won't move. When my water clears up a bit, I'll be able to spot them.
