FYI Two rods per person is NOT legal, during Coho season. Dodgers and worms is another option, for SRC's. Perch fishing is fast n' furious in the Spring--around reed beds. Bobber and worms knocks 'em dead. But am not sure how active they are, at this time of year.
SRC run is over, they are 'colored up' and moving on to spawning up in the tributaries. Yellow Perch population is way down in Siltcoos right now and they all but stopped planting rainbows several years ago: (Siltcoos and Tahkenitch are not "plant and take" trout fisheries anymore, they are managed for the coho runs.) Unfortunately, weather and ocean conditions resulted in very poor coho runs this year.
Best bet right now is look for early winter steelhead in coastal rivers that they are showing up in..cheers, roger.
