i've fished four of five different lakes in king county and the lake that's been most productive is green lake. yeah you're in the city and people are running around you, but my partner and i consistently have catched rainbow trout 16"+ and a few times back produced some 19"+. have been successful with top flies, spinners, and rapalas. fish next to the backside where the lily pads are. oh, and we're using float tubes.
