SMB fishing was really good for us on South Lake--the best was a 20" fish.
I can recommend the camp sites on the north shore of the lake just to the west of Height of Land portage. We liked the western-most one we could see. Recent storms are said to have caused much damage to these sites and, in fact, caused their closure for at least a week or two earlier this summer. I would check that out before planning on any South Lake campsites.
