I'll be heading up on the 20th of this month. If you go across the lake from the launch along that shore line tight (it's deep in close) baitfish always seem to stack up along there. The park guy told me one year most people troll n-s , s-n. That a e-w troll will work out better , seemed to at time for me. That area is like a big basin so you can easlier do that type troll pattern. Remember smelt is the main bait fish so thin profile lures work better. The diver is a good idea get it away from the boat , also long leads off the rigger. lil'boyblue fly , dodger (yellow/green) with a (same color/ or glow) peanut behind it. Small spoons ( they use a lot of moosloc wobblier up there ) I have got them on stinger size also. As your going down the lake to Hauge on your left is two large rocks work that area hold bait as well. Farther south will be some bouys on your right stay to the left of them a shelf come up REEL fast. I hooked bottom in that spot with the deepest down 40' then it came straight up.
Have fun and take some pictures it's a great area............don't forget the ICECREAM store up the road.
P.S. you also have to buy a boat permit for lake george.
