There are chinook in the Sno. I don't know when they come in, I only see them in the fall, and don't usually fish it until then. The fillets in the water makes it sound like someone knew that what they were doing was wrong, and was throwing the evidence away. Sad. The chinook run in the Sno has been declining for years. Even in the ten years or so I have been fishing the river, I have noted the decline. Riffles that used to have spawning fish in the fall are now barren. I wish people would leave them alone.
