You can try this. Lake Washington is a 10am lake. Launch at 68th street ramp (Kenmore) go through the slugh to the lake.
Look over towards Lake Forest Park. You will see a boat house that sticks way out on the lake by its self. Troll 20-30ft in front of it east and west in direction, 12-15ft of water. Use metered leaded line with a brass/orange top needlefish size 0 or 1. Let out about 3 colors, and troll fast enough to see a ripple off of the line as you troll. This has worked well for me in the past especially this time of year, as the fish are headed for brookside stream. Searun cutts are fun. Hope this helps! Tup:
