The Sky is close to you and will put out some summer runs and spring chinook, although it will be very crowded. Farther north you have the N. and S Forks of the Stilliguamish. The N. Fork is well known for great flyfishing for steelhead. Also out west to the Olympic Penninsula, you have the Hoh, which is also a great flyfishing river and has many summer runs, as well as the Sol Duc. You can also head way south to the Cowlitz, Kalama, and Lewis for spring chinook and summer runs. And not quite as far south is the Wynoochee wich gets some summer runs.

If you need a quick fix for any fish, the Forks of the Snoqualmie (very close to you) have many small trout and is one of the better trout rivers on the West Side of the state. Try the Middle Fork is fished quite a bit and has many 6-12" cutts and rainbows. The North and South Forks also have fish in them and are less fished.
