hey driftin,
I don't know much about fishing Lake Washington, but I will tell you how I do my research on a new body of water or type of fishing and hopefully this will help. For beginners I would use the search feature on this website, then systematically go through each post and see what people have to say. It takes a little longer than asking, but you will get lots of good info on the topic. Often I will paste the contents of various posts into a Word doc so I can organize them and see it all in one place. For me its much easier to understand and/or see patterns in what successful people are doing. The next step I'd take is go to washingtonlakes.com and check out the reports/archives for Lake Washington. You should learn a lot there as well. Finally, I'd surf the web a bit (using Google) and see if you can come across any tidbits of information. For example I came across a newspaper on Mercer Island one time with a few articles on fishing Lake Washington that was helpful.

At any rate, just my $0.02 worth. Hope this helps.
