My wife and I went to Helen Lake to spear today. Ice was about 24 inches thick, but water was very murky. We fished for 2 1/5 hours and never had a fish come in. We could see our decoys down to about 4 feet and then got pretty cloudy after that. We fished on the south west corner of the lake in about 8 feet of water. Wondering if it would be clearer in other parts of the lake? Any thoughts?
