what am I doing wrong?

[zooker___________.]

Found some lakes here here in Ft Gordon GA, not catching anything! (except my first jackfish). even my go to lure (Bandit) getting nothing. These are strange lakes, all man made and they feed each other. so no shad. I figure bass are eating bream and maybe crawfish. I lost my Eakins jig-craw on a good strike , dam line snapped. no more braid for me. Ive used a white buzzbait, white spinnerbait(thats what caught the jackfish) Pumkinseed T-rig, Rebel crawfish, and a LIZZARD,lol. nothing. any suggestions? its been overcast, water lightly stained, temp Im guessing still in lower 60's.
