All the times I ever caught salmon off the jetty we still have the beach behind, we did not have to go that far out. At times it can be awesome fishing, as soon as you can get your bait in the water you would have a silver salmon on. We fished a setup similar to sturgeon fishing, put the weight on a slider and rig the herring up backwards, put a cork float about 18 inches above your herring. Use about 8 to 10 ounces of lead.
Ya either check out corkies or Rosalies (ft stevens charters)
