I went and checked the ice on a couple inner city lakes today that are shallow, and freeze 1st every year.
We currently have about 2 1/2″ of ice with the top 1/3 of the ice rotten, or in poor condition. It looks like some of the lakes will be fishable using extreme caution next weekend. Keep in mind this is on shallow, smaller lakes. The large deep lakes might be a couple weeks. No fish is worth taking a swim for!
