The costis and effectiveness of alternative means of 

 Sraolt transport methods including barges, tanker trucks, 

 canals, pipelines, and enhanced flow rates through draw down 

 and or supplemental storage releases all should be compared. 

 It may be that a combination of methods will turn out to be 

 most desirable. 



We are convinced that a research and development program 

 is warranted to determine the biological, engineering and 

 economic feasibility of the pressure pipeline concept. A 

 combination of literature search, lab work and field 

 prototype tests will be needed and we have suggested four 

 phases of work in our report. 



A brief review of the concept may be useful to you.

Entry to exit. 20-70 miles (one reservoir) 



Floating terminals to accommodate reservoir changes 



Discharge to and from existing dam collection 



systems 



Shore supplied pump modules - 5 mile space 



Multiple pumps within modules for reliability 



Automatic clean out valve 



Provisions for exchange of water, food, air at 



modules 



Remote operation and indication of system condition 



Designed for underwater repair 



A prototype test loop, probably full diameter, of 5 

 miles total length should prove out previous lab work and 

 provide a stress test by allowing multiple passes around the 

 loop. Engineering tests such as full scale pump efficiency 

 could be confirmed. Figure 5 



In our exploration of suppliers who could contribute to 

 the pipeline concept we came in contact with Mr. Dolat of 

 Sonalysts. They have excellent experience in designing and 

 installing sonic fish directing installations in the Great 

 Lakes and elsewhere. Their capacity could be important to 

 collection and directing efforts in the northwest as a part 

 of or independent of the pipeline effort.
