I have fished the Capilano River for about 23 years. This is a tough river to fish. It's all dependent on the tides, water levels (due to the dam), and fishing pressure (including the obstacle course set up by the FN fishery).
The Capilano River is like a woman: one day she's hot to trot, and giving you everything she's got; the next day, she turns you down cold. You have to spend time on the river to know her moods, likes, dislikes, and wants. The more time and effort you spend on the river, the more you will get to know her, and say "Forget it. I'm off to the Vedder".
