A guy I worked with off and on over the years was a Steelhead fishing addict. He was fond of saying find Steelhead put the right thing in front of them and they will bite. Salmon sorta the same but leave out the bite part. If they are moving maybe one in whatever bite but nothing like Steelhead. If salmon are staged up it goes to just about zero with the exception being Chinook who are open to GOOD eggs. A bit of blind luck never hurts also.
