Fishing has been good in Port Susan lately, and I've heard that the Skagit has been pumping out a few. If you're 40 mins North of Everett, I'd look at those two options before I'd run down to the big Muddy C. If you're camping you could camp right at Kayak Pt and launch there also. PM me if you are interested. I could run down to the camp ground and give you some pointers. I live about 20 minutes from there.
