Fall chinook salmon fishing in the Columbia River opens Tuesday with the arrival of August including new regulations to dampen the catch at Buoy 10. The big change is that at Buoy 10 — the lower 16 miles of the Columbia — only hatchery chinook and hatchery coho can be retained. This is the first year with no open periods for retention of wild chinook. Also at Buoy 10, fishing will be closed Aug. 21-23 and Aug. 28-29. That’s five days out of what historically have been the top 10 catch days in the Columbia River estuary. A summary of the Columbia River fall salmon fishing regulations is available online at https://wdfw.wa.gov/fishing/management/north-falcon/summaries#columbia.

With the changes at Buoy 10, and the opportunity to still retain a wild chinook upstream of the west tip of Puget Island near Cathlamet, shifts in fishing effort and catch are likely. It will not be a surprise if early closures occur in late August or early September. Swift Reservoir — Swift Reservoir on the North Fork of the Lewis River was at elevation 978 feet on Tuesday. The water has been gradually dropping. Launching a boat at Swift Forest Camp gets difficult when the reservoir drops below 975 feet.
