Your paper cup holds no water.

You have more than just one system that is down in numbers. Many of the systems in Oregon are wild only and allow no harvest and have almost no access, yet those runs are almost gone too. How do you explain that.

I'd buy your guess at harvest if it was true accross the board, but it is not. The Nehalem river is a prime example of a C&R fishery that has 100's of miles of untouched waters and these fish go up and down in cycles, just like the ocean.
