East end off shore steelhead?

[chowder]

I have been fishing for Kings out of Port Bay this summer and some days when the action has slowed I have moved out to deeper water and still searched for Kings w/ some deep lines but have gotten some good steelies on high spoon riggers,cheaters and short copper/cores off the boards. Will this work if I am fishing around the mouth of the Salmon river? If so, where should I start, 250'? How far out do you have to go to find 250',etc?
