 numbers of returning adults (table 4) and in 

 numbers of fish released (table 5). In 1945-60

 536,500,000. At this station during the 16-year 

 period over 166,100,000 fry and fingerlings 

 have been released into the Columbia River

transferred from Spring Creek to other hatch- 

 eries of the lower Columbia River area. There 

 is no area available for natural spawning at
