I'm sure some guys will have a differing opinion but I focus hard on the Duc the last week in October, first week of November. I've always had my greatest success in terms of numbers somewhere in those two weeks. I've only ever experienced HOT fishing on the Duc when its in the weeds.

Earlier in the year I'll focus on the Hoh when its in shape because, IMO, the majority push of fish happens a lil earlier there.

Caught my nicest Hoh river king on October 3rd, 1999, the 42# chormer I posted the pic of in the nice fish/ugly fisherman thread.

Nicest Sol Duc fish came November first last year, released untaped and estimated at 45 - 50 lbs by everyone who saw it..... Each fish was fresh to the river but the Sol Duc fish had more color...

...hope that helps!
