upstream locauon thai showed possible benefits from 

 transportation for the 1986 and 1989 Lower Granite studies. 



8) For sockeye salmon at Priest Rapids Dam, 2 of the 9 

 transponation studies showed possible beaeSts back to the 

 spawning grounds based on coded wire tag recoveries, 2 showed 

 no benefits, and 5 indicated that transportation may ha%'e 

 negatively impacted survival back to the spawning grounds. 



9) Several of the snidies show major differences between earlier and 

 later migrating fish for both the transports and the controls. 

 Combining the data for many of the studies and calcdlating a 

 combined T/C ratio for the entire smdy is an over simplification 

 of a complex interaction of several factors that change over time 

 that are affecting the stuvival of the treatment and control groups. 



10) It is apparent that transponation is not a substimtc for provision 

 of good in-river migration conditions for many of the salmon 

 stocks evaluated in the srjdies. For some stocks it appears that 

 transponation may have been detrimental to fish survival
