The setup that Silver Hilton describes is exactly the system that my brother uses, and most of the boats in the Vancouver area use when they are fishing the Columbia.

I also use that method when anchoring in the current in my personal boat in any of the PS rivers, minus the anchor buoy, since the water is not as deep.
