One of my favorite fishing tips techniques for fall trout fishing is to use live worms rigged on a gang hook rig. A gang hook rig is simply a set of pre-tied hooks in line one after the other and is attached to your line using a small barrel swivel.
This is how it's done: Start by taking the end of your line and tying on a small barrel swivel. Now, tie a set of pre-tied gang hooks or use 9-18 inches or so of leader and tie on one hook. Next, tie on another hook directly to the bend of your first hook and shorten it up so they are only about 1inch or apart from each other. Or if you have the skill, go ahead and just tie a Snelled knot. At this point add a couple of split shot sinkers above the barrel swivel (the number and size of split shot will vary with current flow) for weight. Now rig a live worm onto your gang hooks (if the worms are really large, simply pinch them in ½).
The idea behind this is that you can drift or bottom bounce a worm and have a larger presentation as the worm is laid out over both hooks.
