If you're planning on drifting the N.Fork Nehalem allow for plenty of time. You'll be dragging your raft 1/2 the time, and if you're in a driftboat double that

....I fished it yesterday and it's extremely low. I spotted fish, but they would not bite, and heard the same thing from many others

.
Got plugs, eggs, shrimp, jigs right in front of them and they just moved aside. If you go...Good Luck.
I'd stick to the lower Wilson or give the Clack a shot.
