I'm not sure if you have left yet, but I fish the lake often as my family have a piece of property on the lake. I have the best results on green wolly buggers, green spratlys, 52 buiks, and silver muddlers (shhhhhh)!
You used to be able to catch your limit of 12" trout maybe five years ago, but now you sorta have to work at it, but there are alot of large trout in there now. The lake was stocked with Tzensicut and blackwater trout about 5 years ago that have now grown nice and large. The biggest I have seen come out of the lake was 10 and a half pounds this year. The derby was great I got the third with a 7+ pounder.
Good luck.
