If you want to catch suckers there go in the summer with a pickeral rig and can of worms. Use size 10-12 hooks and a nice wriggling morsel. throw it out about 20 yards just about anywhere. Set it tight and just wait. I remember fishing for them there when i was a kid. I still will target suckers, i like nymphing for them up on Crowsnest Lake (Upper Kananskis was awesome when i tryed up there). Nothing like a 2-3 pound sucker on a flyrod (well, like a 3lb brown or whitefish i suppose). On the Oldman we've caught a few that were close to 5 pounds while fishing for mooneye. Allison Lake they will take dry's often enough as well. (kind of funny). Littlebow river has tons of them, they'll hit pike spoons and average about 2lbs, biggest usually around 4.5lbs. I am not ashamed to fish suckers for at least a few days each summer. I ahve caught some large walleye incidentally giving it a try (usually midday when nothing else was biting).
