Telephone Poles on the Stono

Lately when i put in at limehouse and head towards the harbor I keep coming across floating telephone poles, about a month ago i found a 6 ft chunk and took it but last weekend i tried to pick one up and it was a full pole with 6" sticking out of the water, i ended up having to pull up and leave it sitting on someones dock(sorry if this happened to be you) anyone know whats going on?

I talked to a guy yesterday at Sandy Point that said he has seen the same thing. Pretty scary to think about hitting one at WOT.
