Table 4-. --Eggs collected and adult fall chinook salmon returning 

 to hatcheries in Bonneville Dam pool area, 194-5-60. 1/ 



1/ In some instances sex ratios for Ox Bow, Cascade, Klickitat, and Carson 

 were calculated by using Spring Creek and Little White Salmon data for 

 period 1945-60. Numbers of adults rounded to nearest 100, and eggs estimated 

 at 5,000 per female. 



2/ Willard hatchery is located on Little White Salmon River and all adults 

 returning to that stream are trapped at Little White Salmon hatchery. 



3/ Includes fish handled and eggs taken at the Wind River rack between 

 1945 and 1954. 



Little White Salmon National Fish Hatchery, 

 Washington 



Little White Salmon National Fish Hatchery, 

 located on Little White Salmon River, has been 

 in operation since 1898 and is the second 

 hatchery in importance of production in the 

 Bonneville Dam pool area. In 1945-60 this 

 station has accounted for approximately 85,000 

 fish, or about 17 percent of all adults handled 

 at Bonneville Dam pool area hatcheries (table 

 4). During the 16-year period, 1945-60, nearly 

 151,764,000 young salmon have been released 

 into Bonneville Dam pool area (table 5). 



It is estimated that approximately 6,800 

 adult fall Chinook salmon have spawned 



naturally in Little White Salmon River during 

 period 1945-60 (table 6). Estimates are based 

 on observations by hatchery personnel. A 

 larger population of natural spawners is 

 believed to have existed in the Little White 

 Salmon River prior to 1959, when a barrier 

 dam and new fishway were constructed. Since 

 then larger numbers of fish have moved into 

 the ponds and fewer have spawned naturally. 

 In recent years all releases of fall chinook 

 salmon fingerlings raised at Little White 

 Salmon National Fish Hatchery have been 

 released into the Columbia River at Cook, 

 Washington, to avoid predation in Drano 

 Lake.
