If you go take eggs and a bobber and go to prosser. I fished there a couple of weeks ago and had success. I drift a small berry of eggs with a 2/0 hook and pulled out one bright chinook and lost a couple more. My father in law also did very well. I am not sure what the currentl regs are for fishing for salmon now but if it is still open for prosser and below to the columbia you should look into it. If you want trout and only catch and release go to the yakima ellensburg canyon and fly fish for the trout and steelies. And one other thing have fun they are in there.
