I haven't ice fished Keeley in yearrrrrs. But back in the day, used to go up to Keeley and Canoe quite a bit. I think these lakes now have a special possession limit, so be careful!
Walleye: Anyway, back then, we went straight out from where the river meets the big lake (turn left at boat launch), and drive kinda NE about 3 or 4 km out and find the sunken island/dropoff.
Probably some other shacks, etc out there so you may be able to tell. You go from like 10 feet to about 50ft; that's the drop.
Pike: Not so sure. I summer fished pike along the east shore, where I also caught walleye too.
There's also splake at Fern. Try it!?!?
Keeley has a nice bar/lodge there too! I'm sure some guys in there can help you out.
For walleye, take some fish scent along. I like swedish pimples tipped with maggots or minnows, whatever.
