 River and escapement to areas above Bonneville Dam, 

 1938-66. Runs exclude catches by the sport fishery in 

 the ocean and lower Columbia River, landings by the 

 offshore troll fishery, and the escapement to tributary 

 streams entering the Columbia River below Bonneville 

 Dam. Straight lines have been derived from the least 

 squares method.
