always switch it up
if u are trolling for an hour and no bites, you are proably doing something wrong.
even though the watter can be muddy, try dark colors like perch/ black greens, try reds whites, gold, silver blue/ firetiger's etc
try some harnesses aswell, gold blades will produce,
eerie deeries work super even try trolling a jig.
look for holes and humps and drift white/green/ or black twisters and a 1/4 oz jighead tipped with worm over the holes..
even catfish/ grunts are known to hit cranks, which will def give a great fight aswell.
good luck!
