Steelheading in the EF Lewis River or Washougal

I would like to start fly fishing in the EF Lewis River and Washougal. I am new to fishing in these local streams, and would like to have information on streamside locations to start my adventures. I know that the season is ending for both, but now is the time I would like to do my research. Also, types of flys that produce the most strikes is always a plus if anyone would like to give me one secret. I promise I won't tell anyone. Thank you in advance for helping me out. Hope to see you on the river. :DUNNO
