Used to fish off of the dock by the I90 bridge East Side of the lake. Yes there are Carp in that lake I caught a few in my spin rod days. Also Trolling a streamer or leech pattern can bring a trout or two to the boat. I have always heard good reports for small mouth bass but I have yet to try for them. Also take your fly rod out and fish a bare red hook or a crazy charlie for Sockey when and if season opens for. I am planning to take some kids out this summer to fish for perch on lake Washington. If any one out there know of a productive area for perch to try please email me. The kids will be using spin rods not fly rods. Just trying to pass on a love for fishing and clean water to couple of kids who never got a chance to do things in the outdoors.
