Have been fishing south of Lake Charlevoix, on the chain of lakes and seeing temps in the mid to upper 50's, would assume they are pretty close up there right now.Hammered the smallies this past Saturday over 20 fish in about 5 hrs.Gotta love the catch and release early season, glad the DNRE finally allow us to target them out of season.They were taken in 7-9 FOW.My guess is the spawn will be over or on the tail end by the time you guys make it up, but you could also target Grand Traverse Bay that starts to heat up as soon as the inland lake die down for a few weeks.Heading back out with my son for the opener this weekend.Good luck if you make it out.
