You should consider the "Hi-Lakers" fishing club. I am fairly new acquisition to the group, but they meet monthy at the Mercerview Community Center on Mercer Island. Contact Bill Henkel at billhenkel@juno.com to get involved or feel free to show up. Meetings are the 3rd Wed. of each month and dues are a "whopping" $10.00 to join.
Members range from 21 years up and go into their senior years. We work in cooperation with the DFW to report on the remotest of high country lakes to those most accessable. Each meeting provides a wealth of knowledge which can be supplimented with conversations with the members. The snow pack is pretty high up right now, so most of the lakes are accessable for CT, RB, GT, and Arctic Greyling (the last being if you are lucky). What I've seen and what a lot of the members are reporting is that many of the lakes without inlet/outlet streams are pretty shrivelled up, though still have populations. To get a run-down of the places that you will be traveling consult this link:
http://www.fs.fed.us/r6/r6nf.htm . It provides hyperlinks to all of the State/Federal Forests, giving current information regarding the trails. Good luck, and maybe I'll see you at a meeting!
