Suggestions:
Vary the time of day you fish: early, 9-1pm or 4pm - near sundown. Could make a difference.

Fishing before it rains or before a front moves through has an amazing affect on the number of strikes.

Have you tried light jigs and finesse soft plastics like the crappie or trout magnets? 1/32, 1/24 and 1/16 oz ball head jigs and 6# test braid do well with them. Even overhead spins (Beetle) used with 3" curl tail grubs on light jigs get some big strikes.

Along with finesse plastic lures rigged on light jigs is a slow presentation using reel handle 1/4 turns to impart some slight changes in lure speed horizontally.
