Vet, to answer your question, on the flats, water between 12 and 14 feet there were just a few scattered fish with the shad about 1 foot off the bottom. Then you could go about 150 yards and not see another fish on sonar. The fish follow the shad and most of the water that is 20 feet deep and shallower does not hold any fish right now. The old river and creek channels that are between 20 and 35 feet is where the fish and shad have all moved into the deep water. The most productive areas are on the very edge of the channel on the edges of the drop off. The shad are so concentrated that there is about a 10 to 15 foot thick layer of shad with fish mixed in that the water is so packed that sunlight can't even penetrate, especially in that muddy water! Basically, you just have to use sonar to stay on the edges of the channel to find the most productive water. It appears that the water is warmer down deep. the Crappie dont have to chase shad , Just open the mouth and it fills up on auto
