We have had decent days in May in 30-40FOW. Mostly resident walleye I would assume. The quicker the lake warms, the earlier the migration East. I was surprised to read about the hot bite in Erie in early June. We come from just north of Pittsburgh so I’m sure the locals have a lot more info than I do about the early bite. We usually wait til mid to late June to make several trips. Then hit it hard from July til the end of September. What’s amazing is biologists have tagged walleyes in Lake St Clair that have been caught in Buffalo, NY! So the walleyes travel everywhere and anywhere after the spawn.
