Hilbom found this relationship for the same reason Raymond did. Petrosky's analysis 

 is flawed because he does not account for fish transponed. How does one know whether the 

 high return rates were not due in large part to transport? In 1983, over 6,000,000 fish were 

 transported. There is no disagreement over the fact that low adult returns result from 

 extreme low flow years such as 1973 and 1977. Fish amving at Lower Granite Dam were 

 in very poor condition in spite of the fact that no dams had been encountered before their 

 arrivals.

Same comment at P. VI, Par. 3, line 6. 



P- 7. Par. 2: 



It is conceded that juvenile salmon receive compensation because of their normal 

 depth distribution, but it isn't sufficient to completely avoid symptoms of GBT (gas bubble 

 trauma) or mortality. Intermittent exposure is irrelevant to juvenile migrants. Once the fish 

 are in a block of supersaturated water they have no means of recovering in unsaturated 

 water. 



P. 7. P^ , $: 



Throughout the duration of the studies done by Meekin and Turner and Weitkamp and 

 concentration of TDG were nearer 120 percent than 126 or 128 percent. The high 

 concentrations of the 126 and 128 percent occurred only on one day of the tests. 

 Considering the clear water (fish tend to be deeper in clear water, Dawley et al., 1975) and 

 the duration of the tests, I would not expect mortality. They do not refer to a test done in 

 the Snake River where concentrations of TDG were 127 percent for the entire duration and 

 48 jjercent mortality occurred in the volitional cage 4.5 m. deep. 



P. 8. Par. 3 : 



Both the Ad Hoc Transport group report 1992, and the Mundy et al. 1994 repon are 

 seriously flawed. There are some errors and omissions of data in the Mundy report, but the 

 main flaw in this report is that the executive summary and conclusions do not always agree 

 with data and information contained in the text. There are criticisms of the experimental 

 design throughout the report. Appjarently the review group was not aware of the fact that 

 many elements of the experimental design are dictated by the agencies. Such things as 

 numbers of fish marked and location of releases were usually changed or regulated by sute 

 and tnbaJ agencies. For example, on several occasions NMFS was not allowed to mark any 

 experimental releases. The executive summary also omits commenting on the fall chinook 

 data from McNary Dam which is overwhelmingly in favor of transportation. Generally, the 

 executive summary highlights the negative aspects and omits the positive. The quote by the
