This is a very difficult question. I would say that if you look at the lake as most fishermen you would be fishing on one of the places that you see the guys fishing every time you are out : state park, or by dove island or one of the other popular drop offs..... Many people or most, fish anywhere from 4 to 25 FOW hundreds of tip ups and no walleye!? Is it a daytime thing? Go deeper? Color? Baromiter ? Feeding or not? What I am saying is a combination of it all. I have iced eyes in the daytime there and at night. It is just being there at the right time. The walleye in winter: deep. Not saying you will get one but not many people have. Strange thing is I love the challenge. I am still looking for my secret go to lure. I look at this kind of stuff different than most people in the way that I only am looking for one hit or bite. Yea I am nuts but It is only time until I figure out somthing to put them dry side more often. I have have once walked off the ice with my limit, full moon and all on tip ups. Go figure and good luck.
never ice fished it. open water i go to where the major drop offs meet the lakebed. jig directly on that crease up and down the drop off. literally directly on theat crease- through your hole you should have more slack in your line when on the deeper side vs the slope drop off shallower side of your hole. use your navionics iphone app or previous knowledge to fish directly over these edges. damiki vortex in silver halo represents a fleeing herring really well. franks tackle has em. jig that baby up n down, bottom to 18 inches off bottom, back down. You know they are there, the state got over 500 in 3 days ! Just knowing that can drive you crazy.
If it helps. Try looking at nj fish and wildlife web page I am sure that there is a depth chart of the lake. Of course not as detailed as you would like but will put you in the right area. If you have a flasher watch the bottom, if your on mud or rock.
I prefer the shad size rap. I like the profile and it isn't too big. Tip it with shiner head, mousies, fathead, I have even used dead frozen herring. It is just finding them. You have a lot of territory to cover, travel lite. I use tip ups too to cover area and depths. With them cover the water colum. 1 to 10 feet off bottom. I would say they might be in with perch feeding on them as they are getting ready to spawn soon. I like deep at day and points and drops at night.
It never happened if there are no pictures!
