Guided John and his 9 year old son Hunter for a half day starting at 6 am. Bite started out well with John hooking two solid fish and landing one over 27". Then things slowed for us. By around 9:30 fish were showing some signs of activating again. Hunter hooked and landed a laker around 20" then John caught another around 23" before we called it a day. The thermocline was set up with around 60/62 degrees on the surface and 48/50 down around 75'. Of course, these depths and corresponding temperatures will vary depending on what side/end of the lake you're on and where. But that's what we found N. of Long Point near Aurora. No lampreys or fresh scars on any of the fish.
