You should be able to walk most areas of Trude Lake, especially from the boat landing side... Where it dumps into the TFF, it may be open water already. That said, this time of year bring your safety gear. It may save a life anywhere and you never know where. We are supposed to get anywhere from no snow to 12" during the next few days, so no idea what that will do to the ice either and even early next week, they are still calling for mid-30's air temps. I actually have a friend who put his boat in and caught fish from Saxon Harbor during the last few days.
