That is exactly how we normally fish the Red River from shore. I like to keep the leader length to the hook short, approx. 8 inches long, and the line to the sinker about 3X longer than the hook length. This keeps the hook riding slightly off the bottom and prevents it from snagging as easily. Here's the key to fishing like this; Do NOT break off and reel in each time you notice that you are snagged. Let it sit out there. Since you know it is most likely just your sinker that is snagged, wait for a fish to take your bait, and they will do the work for you in an instant. If you haven't had a bite in 10 - 15 minutes (or whatever length of time determined by how hot the bite is), then try to free yourself from the snag in case your hook is snagged. The one time when a sliding-sinker rig works well there from shore is when the water is low and the current slow. Then provided that you use a flattened no-roll sinker, you can get away with such a rig as it will not drift much before settling. By the way, the 3-way swivel rig works great in lighter versions for other species wherever there are snags. I have used it with success fishing below the weir in Saskatoon as well.
