The split shot rig may be one of the most popular rigs for targeting cutthroat trout in rivers and streams because this rig can get your bait down a little bit, but stay out of the rocks if there is enough current to pull it downstream. The key is getting the right size weight with the current you are fishing. If you can figure this out, you can fish a variety of live bait, natural baits, flies and soft plastics without getting hung up.
