Yeah Montesian freezes up pretty good. I've never ice fished the exact aerator locations, but those aren't really where I catch fish in winter anyway. The Lion's Club has an ice fishing tournament there during the (I believe) first weekend of February every year if you're looking at doing something like that. It's a good time, there's a good amount of anglers, and they sell some good chili.
Thanks, there's a few nice pike that I think I can pull out of there.
It does lock up completely. Just gotta watch by the aerators as it can be a little sketchy.
Does anybody know if this lake still freezes up in the winter. I know they have an aerator in the summer, but I'm not sure if it stops the lake from freezing in the winter.
