"believe it or not lake washington can be pretty fun from a pontoon boat in the right places when the water starts to warm but before the eurasian milfoil bloom explodes. it can be intimidating because it its size, but there are mega trout in there and they still have to eat." I have heard that they quit stocking Lk Washington with trout. Has anybody noticed a significant difference in the quality of the fishing? I have tried fishing Lake Washington for trout quite a few times over the years. I have caught a few (on gear and flies), but never any consistency.
