I've got at couple of clubs that I belong to that you might like:
First I've got to agree that its hard to beat the Overlake Fly Fishing Club. Best decision I made last year. It is truly a flyfishing community. It costs $35 to join and somewhat less than that for the annual fee, but your money goes to a reserving the location for good dinner each month, guest speakers, and renting out a room for a mothly fly-tying roundtable where some real savvy tiers teach you things from their experience. You also have access to a large how-to and destination video library and boxes upon boxes of flyfishing books that you can check out from the library. Be friendly and open and people will eagerly share their knowledge and friendship with you.
The other club is the Washington Hi-Lakers. Cost of the membership is an annual payment of $10-15 which essentially goes to to reserving the room at Mercerview Community Center in Mercer Island. The members of this club are generally pleasant, but it is not as intimate of a setting as the OFFC. What you will find is this club will teach you a great deal of info about indentifying races of trout, salamanders and other amphibians, and you will obtain information from guys that absolutely love to hike into aquamarine lakes that are surrounded by granite slides, cliffs, glaciers, and chock full of cutthroat. It appears to me that generally, the club is more into hiking than fishing. The club is full of total smart-asses and their humor enought is worth the $10-15. Regardless, you learn to survey lakes which is a trait that that gets you in good with Fish Biologists. You may even obtain information about "zipper-lip fisheries." Golden Trout, Grayling, larger Cutthroat... I would describe the relationship between surveyor and Fish Biologist as highly symbiotic.
