Anchovies make great salmon bait they are the primary bait in the Rogue Bay. I have used them on the Coquille and Umpqua with success. Typically you would use a threader up though the anus out the mouth with a treble hook inset into the anus and a small hoof fwd. though the nose. Most people will use beads and a spinner above the Anchovie. I don't know about the Sandy but you can use them in many other rivers.
