Fishing for cutthroat trout in the tidal portion of the Fraser River, at least down here in Steveston where I live, never gets "hot" but there are always the odd fish around. Most of the time you catch nothing, occasionally you get lucky and hook one. Sometimes you are even luckier by hooking a few during one outing, but those situations are rare.
In my opinion, fishing has been fair to poor for not just cutthroat trout but also northern pikeminnow and other predatory species with artificial lures or flies right now. My speculation/excuse is that these fish have been feeding on the high abundance of sockeye salmon guts etc in the river after each commercial harvest. The water condition has been excellent, so there really isn't a reason not to catch any if there's no feed in the water for them.
That being said, I did encounter a fine fish a couple of weeks ago with a small spinner. It could have been a coho jack as it jumped several times before the hook popped out by my feet.
This is typically the time of the year when the chance of connecting with a cutthroat trout increases.
