Thanks guys for the great info. J. Sporrow-I printed off your graphic, just what I was looking for. I do have a 100' temp probe to find the thermocline, used it for a starting point for years on Lk Ontario. After we get some 'eyes on ice we'll try jigging up some lakers on our light outfits. Even 2-4 pounders here in the Finger Lakes is a hoot on bait casting rods with 10 lb line.
Again, thanks for all the help. If the weather/wind forecast cooperates next week we'll make the 3 hour run out. Did well this time last year we'll look for a repeat.
I'll give a trip report when we return.
