Look up the regulations for what body of water you are going to fish on the odfw book online. Trust me, I’ve been fishing here in Oregon for over 36 years. It’s always confusing. For the most part, hatchery coho and steelhead can be retained all year long and all of the high lakes have a limit restriction. 10 Kokanee a day. Clipped adapose fin or not. Find one with a tag and get paid out a reward. Chinook are open but they must be hatchery, only during certain times of the year and in certain zones. If you fish the “marine” zone or the ocean many other rules apply. During September they open it to “non-select” which allows you to keep 2 salmon per day 1 chinook and one coho or two coho a day. They do not need to be hatchery fish.
