Went out today in Tennessee and tried my hand at bringin home some slabs. Air temp was about 45 and water temp ranged from 46-48. So I naturally thought that the fish would be deep. So I started in 16 FOW and varied my spider rig accordingly. Not a single bite. So OK i thought maybe they are deeper. WRONG. went to 20-25 FOW and fished from 12-20 feet deep and struck out once again. At first i just thought it was a bad day but after calling a buddy of mine on the way home. He limited out in only a few hours. He said he was catching them 3-5 foot deep in 8-10 FOW..??? Can they really be that shallow with the water temp still being in the forties this time of year. Im still learning obviously. Any of you guys have any input?
