River salmon fishing help needed

[Chinookman]

I fished the pullayup river in washington three days straight and no salmon caught. I used spin and glows, prawns, eggs,spoons,spinners and flies. And not even a hit from a salmon I was fishing from the bank. I was fishing for Chinook salmon. Can any on tell me a trick they use on lock jawed salmon that might work or what they use on hard fished rivers. Any tip or advice would help thanks.<br><br>
