pipeline water coluan. Injection of air or oxygen, food and exchange water 

 could also be provided at inter-zals along the line. Ejections of sand, silc, 

 detritus and exchange water could also be provided. 



It is envisioned that a reach of this pipeline would be from daa to dam with 

 inspection and small resting terminals at the sending and receiving ends. 

 The collection and transport at the dams would be integrated with the existing 

 and planned screening and collection systems. Discharging of fish would be 

 below Bonneville Dam at a single point or distributed over several miles by a 

 pipeline with turnouts. 



Figure 1 shows the overall concept of the system and Figure 2 the details of 

 the pipeline suspension system. Figure 3 shows a pump module and Figure 4 

 shows the exit and entrance pipeline terminals. 



If smolt losses between Lewiston and Lower Granite Dam prove excessive based 

 on current testing, the pipeline reach could be extended upstream to a new 

 collection facility near Lewiston. It is expected that the need for this new 

 facility will be the subject of a separata study. Also, if further experience 

 shows smolt damage due to passage from the dam collection channels to the 

 tatlwater facilities is excessive, a 10 cfs fish ladder dedicated to smolt 

 transport to the next pipeline terminal could be incorporated into the design.
