You can get onto the ice at the katepwa boat launch with a 2wd and go out for a few hundred yards.....from there on I can't tell you-that's as far as I went. Just got out for a few hours this afternoon--not much biting, only small perch and burbot, when I was there, although lots of fish showing on the flasher...the big guys weren't interested.
You have to be careful there, as there are some nets under the ice, but the ends are well marked.
