 The Cass County Sheriff's Office is asking everyone to be wary of changing ice conditions. The unseasonably warm December has caused a few lakes to begin deteriorating. The thaw-free cycles have opened up large cracks and ice heaves on few area lakes. Right now, the area of Walker Bay of Leech Lake is extremely unstable due to a late freeze and a large crack that extends from first point to the middle of Walker Bay. The Cass County Sheriff's Office reminds everyone that no ice should ever be considered safe. Check with local bait shops, resorts, gas stations and other fishermen for ice conditions and also to always carry a cell phone and let someone know where you'll be and your expected return time. You should also carry a map and pay attention to any warning signs that are posted in the area.
