I’d put this question in the Lake Superior forum found in the Minnestoa State list. Grant Sorenson or one other of the locals can offer up a lot of information on this area. Jim Hudson is another one that comes to mind with great info.
Personally I know that smallies are BIG abnd sassy from that area and they can be caught from shore in some areas as I have done in past trips up that way. If you can find a rocky shoreline with some easy access you’ll find smallies. You might find a trout of some sort as well but I think they can be seasonal. I have always just cast spinners like a Mepps in a size 3 or 4 and have tossed some deep shad raps too with good luck.
Don’t go if it’s windy unless you have a strong stomach. The ferry crossing can be brutal at times if the wind is howling! Other than that I can’t tell you much because all I’ve ever done is drive the road up and back. I would’ve loved to stay and explore a little more.
“BIG BAY” park on the east side has one of the nicest beaches on Madeline, for the family – miles of white sand. If you can, rent a canoe, and fish the “landlocked” bay just behind the beach/park – both lg & smallie bass, pike.
Big bay park is great. Take some float toys and the kids can ride the tide up and down the stream. My daughter had a great time when we were there about 15 years ago.
