I plan to make my way up to a particular lake that has rainbows in it tomorrow, but no salmon run. I have fly fished for steelhead throughout my life, but that's almost the only time I break out the Sage (except grayling).
I don't even know how to fly-fish a lake very well except to throw out a dry fly. Maybe someone could recommend a few good lake flies for this time of year. I'll have an old-school float tube and some gigantic diving fins.
