This will be my 3rd year fishing the big lake. By no means makes me a expert on the lake, but I really enjoy it alot. I fish it every weekend druing the summer that I can. I have only fished lake Michigan one time, but sure same fishing lures, speeds, etc are the same. Temp. is probably only thing really different between the two lakes, being the lake Superior doesnt get as warm as Michigan. I have fished Superior from the harbor to Two Harbors and done good both places. Depending on which way wind is from tells me where to fish that day. By the port of Superior you can catch cocho, walleye, lake trout, right by the breaker way in the spring, later in year go out from there about 10 miles look for the mud line and we catch nice lakers there too. Two Harbors we have caught laker and coho from just surface fishing to downriggering, again depending on temps. So I would tell him its very much the same as fishing lake Michigan, might not be as big of fish just becasue water temps cooler, but sure is closer!! Good luck
