Mornin poking holes, Prior to moving to Alaska 4 years ago, I use to live about 30 minutes east of Chetek and fished the chain summer and winter for 20+ years. To my knowledge, if you are a resident of Wisconsin and taking your wheeler on public property, this includes any body of water not listed as private, the law states it has to be registered and displaying your issued decal. As a non resident I believe your good to go. But, certainly do as much research as you can prior to going. I'll contact a buddy of mine who lives on the lake to verify and get back to you. As for the catch, you can pretty much catch crappie, perch and blue gill any where on the chain, it can be that good. I'll check some areas that my pal is fishing and get that info for you as well. Where are you coming from by the way?
