depending on how old your newphew is and what kind of fishing experience he has, you could be setting yourself up for a L O N G day. there are over 1000 standing trees in the lake. get a Frabill Lure Retriever before you go (the pole style, that extends). it will pay for it self your first trip.
if your nephnew lets his lures sink a lot, he/you will be spending much time trying to get lures back. honestly, 1000 standing trees in that lake.
check out the weather before you go...that place is a wind tunnel.
