Hey guys, I'm new to BC and this message board. Just wanted to say hello and ask for some help from you very knowledgeable posters.
I have read things saying that the Cap can be very good fishery, but others saying the exact opposite.
Welcome to BC and the discussion forum. You're seeing contradicting fishing reports because the fishing results may fluctuate greatly, mostly due to the fluctuation of the water level. The Capilano River is dam-controlled. During days with no rain, the river is extremely low. On days with periods of rain, the river may rise suddenly, providing opportunities for salmon to move into the river and upstream. Because the window of opportunities for fish to move up is small, they tend to move very fast. Fish can travel from the mouth to the hatchery in just hours sometimes. The move is also quite tidal influenced. A high tide that coincides with a high freshwater discharge gives you the best chance of encountering fish.
because the river can fluctuate unpredictably, one should also pay great attention when using the river. Wading should be done with extreme care, crossing the river is not recommended. Watch out for loose or slippery high banks. Lastly, be aware of wildlife in the area.
The Capilano River has a coho salmon run that is uniquely earlier than other streams in the Lower Mainland. It begins in April/May and ends in October/November. Fishing has a tendency to slow down in July and August, because these two months tend to be dry. Most of the fish have a tendency to hold at the river mouth or nearby beaches during this time, so anglers tend to focus on fishing in the salt than in the stream.
The main fishing spots, as you have mentioned, are Cable Pool and under the Hwy 1 Bridge. These are the two most easily accessed locations, which make them the most crowded as well. There are numerous other spots that can be reached from these two spots by foot. You can explore them by studying the map that Verdi emailed you. Tread carefully when walking downstream from Cable Pool. It is wise to let others know that you are accessing this section of the river.
In spring and summer, early morning is best when targeting these coho salmon. The easiest method to catch them is by float fishing with roe, but casting spoons/spinners or flyfishing can also produce well.
There are many other streams in the Lower Mainland where you can fish, however salmon fishing does not start in most of these streams until September/October. From Coquitlam to the valley, you have the option of fishing Coquitlam River, Alouette River, Stave River, Chehalis River and many other smaller streams on the north side of the Fraser River. On the south side, the Chilliwack River is the most popular stream to fish due to its productivity. It offers red chinook salmon fishing in July and August. When exploring all these streams, look out for seasonal and location closures.
Good luck.
