From a very negative, very snide view of the closures, consider this. When I was still working as an officer for WDFW I "met" people frequently fishing closed waters/closed season not by mistake but for a good opportunity. They were just going to go fishing no matter what, and would pay the price of a cheap ticket, in order to keep fishing where and when they wanted. And they were seldom caught. The Nisqually during late winter was a good example of this. So, the rivers are still open to a few that will risk the payment of a cheap ticket - cheap as long as you don't kill a wild fish.
