Compliments to your planning, research and optimistic outlook.
#1 You're at the right website for up to date info #2 upon your arrival stop by the local sporting goods to pick up the current fishing pamphlet #3 get ahold of a "Washington Atlas & Gazetter" (map) #4 get a copy of "Fishing & Hunting News" for Washington State. (It'll give you a good idea on what's available in this state)
Good Luck...><>
