My only other suggestion would be to stay away from some of the spots around Sault Ste Marie. Munuscong Lake, normally a hotspot for eyes, has been VERY slow. A recent derby there had record numbers of anglers (very nice weekend), but only a few wallys and perch caught, and most were small.
Otherwise, you seem to be in the right spot. Look West, young man. Luce County, Schoolcraft County have some small lakes that look to be excellent fishing opportunities. Pretty Lakes Quiet area has lots of lakes - you may be fishing on a walleye lake and in close proximity to that lake, you may have a good perch/pike lake, as well as a good inland trout lake (rainbow, splake, brookies). I have lake maps of the lakes in the Eastern U.P. with regular summer access. But I won't be able to tell you specific reports on the lakes.
Good place to start: call Curtis Fish and Hunt Shop - (877) 586-9531. Website:
