Don’t know a thing about it. But, check out the WI DNR lake search for some information, and if you have a strong stomach, lake-link as well for “reports”-or use their lake finder page for some info maybe? If nothing else, l/l might list a bait shop or guide in the area that you could call. Good luck!
