Like I said, It will disappear quickly if placed shallow and it gets exposed due to lake drawdowns. And like most everything else, there's times the fish like the 'boo and times they prefer another type of structure.

Shallow water I'd recommend following Nimrod's advice and place pallet beds or drive stake beds with good hardwoods.

Just my opinion, and it's not worth much. I don't catch near the crappie most of these guys catch.
