Yes all of the regs are subject to change, when necessary. I have fished the Chehalis for almost 30 years. Some of you many more. I have fished in December every year when it was open. About 15 years ago I heard of a steelhead being caught. So when closing the river to protect steelhead happens? All that needs to be done is a bait restriction. No Bait, no scent. Hardware only. Otherwise there will be a lot of excess coho upriver.
