I have seen several musky caught in the past 10 days, most were caught on large plastics from what I could tell. Medusa type baits cast over mid depth structures and ambush locations appeared to be the winning method. Have yet to see trolling or sucker rigs be the ticket, but I do not personally target musky.
With water temps dropping the bite should only improve. Panfish and SMB have been biting along the river channels and some perch have started to move into shallower areas. Walleye have just started to bite again.
