TyW33, another assumption we make is that our fish species have to be all or nothing. SMB don't have to be your only or major predator. You can put in SMB, walleye, wipers, etc. as money or access to fish allows. Then tell everyone that you will do great bodily harm to anyone that removes these fish. They can harvest the other species but not these.
If you have a sand pit, I've always wondered why you haven't stock it by now? Just because it is still being dug out doesn't mean you can't have fish in it. We are still digging out our lake but stocked it as soon as it held enough water to support fish.
