I've only fished plum bayou a couple of times. It is muddy a lot when rain comes in. I had some luck bass fishing in there throwing a big spinnerbait in muddy water. Even caught a couple of crappie too. The main channel stays about 7-8 ft, but it shallows up in the trees real quick, 2-3 ft. Most people troll the channel in the winter, but during the spawn, they will be anywhere in there in shallow water.
