Recently i was at baldwin lake drifting in the 30 foot holes when i noticed that the fish were sittin in around 15 to 18 foot of water rather than towards the bottom. is there a reason for that?? is the water ready to turn over???? i only caught fish in shallower water but the deep water was loaded with bigguns but just not on the bottom for driftin. would maybe a slip bobber work for that????
