I fish Ste Anne a lot and find the same; class C can be tough. Vast majority of the walleye I catch are class B, a fair amount of Class A and few class C.
I would say for the next few weeks I’d fish around the old reed beds in about 6-10 feet of water. Fish all around the point around RR40, both sides of the entrance to the narrows on the big side of the lake, and along the shoreline near Windmill Harbour. Should be able to find some smaller ones. Hopefully.
