if you are talking about fourth lake of the fulton chain,your best bet is going out from the state launch on rt.28 in inlet.you can walk out 100' or a mile and fish.with that being said,the launch is also a major pathway for snowmobiles,so i would recommend going off to the left or right a ways to try to stay out of the main path of the sleds cause it becomes an absolute zoo out there,especially on the weekends.off to the right cedar creek comes in and off to the left a ways,fifth lake channel comes in and the ice gets thin very quickly.the woods inn is just down the road from the launch,if you get a room there,you can walk right out from the hotel.rivets marina,in inlet,about a mile from the launch,just started selling bait,315-357-3231,i think they also have an ad on facebook.
