Has nothing to do with your line. Placement and timing is everything

Well i must be doing something wrong here. I have been fishing Texoma in the middle of the afternoon (i know its not the ideal time but i should still be catching fish), and been targeting fish in 20-30' fow. From what i have researched they should be staying deep during the day and coming shallow at night to feed. I have tryed drifting, i have tryed still fishing; i have fished coves, the river channels, flats...basicly anthing in the 15-35' fow range....what gives? Am i fishing too deep? I thought they would be near the thermocline in deep water. I use fresh cut shad when i can get it and that seems to make a difference but im still not hammering them like some of the guys on here do.

Well don't judge yourself against guys on here. Most that fish a particular water body have done so for a while and or are out fishing these water bodies more than you may. And they may have a pattern on that body of water. My last trip to texoma seemed to me there are a lot of meat hunters there. I boated past a string of identical jugs and when I say string there were 30+ jugs in one area until I got to the next set. Which had just as many if not more. This may ruffle some feathers but if guys are doing that more and more then your fishing is effected by this. But to point how are you locating your fish? Random guess, spot you know? Electronics?
