This topic is awesome, so is it safe to say that a pallet sunk on the bottom of the pond in shallow water would be less useful for spawning fatheads due to the temperature being cooler under the water than at the surface? Would stacks of pallets that just hit the surface of the water work good too, I would think this would be a like the projects for fathead minnows. Does rough cut lumber work ok for them to spawn under or should it be planed?
