Thanks Leo. I definitely would prefer natural rock vs. concrete but dang it's just not much of an option down here by the beach! I believe the biggest issue will be trying to get "clean" concrete as opposed to that which has say pavement with it.
I guess with the mesquite trees the only thing I really need to do so keep them from all floating to the same end. I believe a t post and wire will do that. My plan was to put them in the intermediate depths of six to eight foot and then do the deeper portion of the lake with my vertical artificial trees.
