Columbia River Chinook anglers can celebrate the Fourth of July with some fishing, as fishery managers announced that the lower Columbia River is re-open to summer Chinook through Sunday (July 6). The fishery will be open from the Astoria-Megler Bridge upstream to Bonneville Dam with a daily bag limit of two adult salmonids – Chinook, steelhead or sockeye – per day. All Chinook and steelhead must be fin-clipped. Oregon and Washington fishery managers announced the re-opening of sockeye salmon retention on the lower river through July 31. The re-opening is based on run strength and the harvest to date. From this, managers calculated there were enough fish remaining on the harvest guideline for four additional days of fishing.
