Any short run river ( IE Vedder, Harrison ) White chinook ,,, are called " Tuley whites, originated in the Columbia river lower streams. They are very acid smelling and tasting. Long river whites are every bit as good as the Reds but just don't look as nice. Upper Fraser whites and reds 600-700 mile fish are fine. Stay above the Harrison and most of the kings are fine.
If you do take a short river White nook. ,,,,make sure you just scrub the heck out of ANY trace of slime on these guys they will be also okay. I mean SCURB every malicule of slime and your fine. Most of us won't go to that much trouble . That ugly strong smell and taste is from the slime getting on the meat. Do it before you clean your fish...... SCRUB !!!!!
