Got out for a few hours on the south end. Fishing was poor during the time we were there (12-3 in the afternoon). Off-road travel impossible if you don't have a sled or plow truck.
Denny's had several spots plowed out that you could set up along side. Minnow heads and full minnows were all they'd take. Kept 12 (5 guys fishing), biggest was 8".
Didn't actually measure the ice, but the extension came in handy. Well over a foot of snow on top of the ice, water pooling up around all the holes. Don't drill near the roads or you will flood them.
