What do you mean? How do I attach a float, how do I hook to the anchor, how do I attach the breakaway string? Are you asking about anchoring for salmon or sturgeon in the columbia? The answers differ a bit depending on what your trying to do.

For salmon fishing in the columbia, I use about 200 feet of rope, connected to about 4 feet of chain, connected to a rocking chair style anchor. For the float I use about a 15 inch orange mooring buoy. The buoy is tied in to the rope about 15 feet from the end, then I put a crab pot float right at the end of the rope to make it easier to see and pick up.

If I missed the question feel free to shoot me some mail.
