>>492412the rig i would suggest is a small float ( nothing bigger then a quarter ) with a horisontal hanging hook( trout magnet hooks are really well ballenced and a great size, though they will bend and start to streighten out if you arent careful fishing a big fish ) under it with dangiling section of worm
toss it up river and let it float down,
try ifferent depths until you hit where the fish are, look for cover , big bolders breaking the current etc
