Oregon and Washington set recreational spring chinook and winter steelhead fishing seasons in the Columbia River downstream of Bonneville Dam that in April limits the number of days per week anglers will be allowed to fish. And, beginning March 1, angling for salmon and steelhead will not be allowed in the river from Warrior Rock at St. Helens, OR downstream to Buoy 10 to protect hatchery fish returning to Cowlitz and Lewis river hatcheries.
