If you don't flyfish, spinners work too. As do rapala plugs, but make sure the hooks comply with the regs. Best fishing for me has been on a rising tide, and don't be shy about fishing very shallow water. I have also fished them around floats and docks in Pender Harbour. Casting blindly into the deep water or along neighboring docks often produced chasers if not biters.
I am no expert and I haven't fished them much, but flies and spinners have worked for me. And a worm under a bobber works too. They are trout after all, and they eat all sorts of creepy things, not just fry and sticklebacks.
Good looking fly, btw.
