Columbia River Zone 6
All four Columbia River treaty tribes enjoy fishing rights along the Columbia from the Bonneville to McNary dams. This 147-mile stretch of the river is called Zone 6.
For fisheries management purposes, the 292-mile stretch of the Columbia River that creates the border between Washington and Oregon is divided into six zones. Zones 1-5 are between the mouth of the river and Bonneville Dam, a distance of 145 miles. Oregon and Washington manage the commercial fisheries that occur in these zones. Zone 6 is an exclusive treaty Indian commercial fishing area. This exclusion is for commercial fishing only. Non-commercial sports fishers may still fish in this stretch of the river.
