Something else to add to those who are complaining about the difficulty in catching Coho.
In well over 3 decades of fishing the Chilliwack/Vedder, this has been one of the easiest years to catch Coho that I can remember....and that includes the time when you could legally bonk wild fish.
Everything goes in cycles....and I can remember:
1. Years where the pink, chum, and even the white spring runs were enormous.....and they literally choked out the Coho. >Even the pocket water was challenging (but still reasonable)Right now, it is mostly Coho in the river.
2. Some years, there are early floods that activate the clay banks. This year the water is low and clear, but first light still produces fish.
3. My first almost 20 years on the river did NOT have an internet online real-time Hydrometric data for water level and flow. On the nights before I went fishing the next day, I used to have to put out a rain measurement gauge so I would know whether the river had blown out. Now all you have to do is wake up turn on the internet and find out in 30 seconds whether the water will be fishable or not.
Again....take advantage of this year. Although, I catch a good number of Coho every year.....this year is one of the easiest years for Coho success that I can remember.
