Here's some info from Greg at Musky Mikes. Looks like most people are hitting the smaller lakes. Becky Smith's report at her shop's page from earlier this week (dated 1-18-12) says pretty much the same thing.
My info isn't much different. Because of ice conditions before the freeze this week, most people have been out in the protected areas/shallow bays/small lakes. Now that we've had a solid deep freeze, expect to see some movement to bigger water.
Stay safe. The snow is covering up some sketchy ice. Standard rules apply: PFD, Buddy System and spud bar use.
Here's what I got in over the last two-three days. Getting a little more specific info this week.
Okauchee: Icehouse has between 3-8 inches. Pike have been very good along the south shore cut, just past the drop off. A few larger pike have come off the deeper water around the sandbar-roadbed area at the mouth. A few crappies are in the deeper hole just inside the bay. Bluegill action has been spotty.
Okauchee: Bay Five Ice goes from solid to sketchy, especially in areas where the current is directly flowing in and off of the main channel. Pike have been very active, but smaller. Bluegills are biting a couple times a day, and stacked up over the larger brushpiles/wood laydowns. No word on crappies.
Golden: Pike are active on the south end. Ice on North end was shifting some, and a little thin in spots. Panfish would bit if you could find them, but the larger schools of keepers are suspending off the deep weed edge areas in 15 FOW.
Silver: Lots of people have been out, but reports have been a little thin in terms of action. Smaller gills and a few undersize pike. One guy I talked with, who is a pretty reliable source said he couldn't keep the bass off his tip-up minnows the other day, but he never caught one over 12 inches.
Kessus: Other than reports of a monster pike (it gets a little bigger each time I hear a different person talk about it now-it went from a 36" to a 41" in a matter of minutes) that have been making the rounds, bluegills seem to be the hot action on Kessus. Shallow ends of the bays and the marshy area have been productive.
Nagawicka: Kettle...I know its been busy, but none of the people I have talked with have been out there. Becky's people at Dick Smiths or Greg at Musky Mikes will have better information.
Ashippun: Always a winter sleeper, Ashippun has been providing some decent action for pike. Ice reports are that it goes from solid to thin in a matter of feet, so be careful, but look for pike in the reedy area near the launch. Gills and crappies have been out deep and on the bottom.
Good Luck...and be safe...
