ODFW release - CLACKAMAS, Ore.—Fishery managers from Oregon and Washington took joint state action today to add another three days of recreational spring Chinook salmon fishing in the mainstem Columbia River downstream of Bonneville Dam. This fishery had closed on Wednesday, April 8 per the preseason schedule adopted in February.  With the additional days, the following regulations are in effect:  Dates: Chinook retention allowed Saturday, April 11 – Monday, April 13.  Daily adult bag limit: Two adult hatchery salmonids (Chinook or steelhead) per day, but only one may be a Chinook.  Open area: Buoy 10 line upstream to Beacon Rock plus only the Oregon and Washington banks from Beacon Rock upstream to the Bonneville Dam deadline. For exact boundaries see the ODFW Recreation Report for the Columbia Zone. Shad may also be retained.  Fishery managers will continue to evaluate fishery performance and Chinook abundance this spring and will consider additional fishing days if possible.  The fishery upstream of Bonneville Dam (from the Tower Island power lines upstream to the Oregon/Washington border) started April 1 and is scheduled to continue through April 26. Additionally, the fishery is scheduled to be open May 2.  All other permanent regulations are in effect for salmon or steelhead in mainstem Columbia River waters from the mouth upstream to the OR/WA state line.  Anglers should always check for in-season regulation changes before fishing, see updates in the ODFW Recreation Report.
