apparently In the order of lOJ per reser-/olr. High nacural runoff, deliberate 

 upscream storage- reservoir water releases, and now reduced reser-zoir operating 

 levels during the smolt migration season all will contribute to higher water 

 velocity and, presumably, better survival. However, these measures may also 

 result In significant costs to power production, agricultural water supplies, 

 and navigation and recreation (the latter two, in the case of altered 

 reservoir operations). Reducing the transit time by collecting and 

 transporting the smolts downstream by barge or truck has given good results 

 with some species, but appears to disorient others and result in poor adult 

 return rates. Alternative transportation is currently being examined by a 

 small group who are concentrating on the open channel or canal approach. 



A pipeline transport alternative Is described in this report. This 

 alternative will require a series of tests and explorations to validate its 

 feasibility from a biological, engineering and cost standpoint. Uater 

 velocity for the pipeline system could be in the range of 2 caJV feet per 

 second or 1.4 to 2.7 mph which would result in water particle transit times of 

 between 4 and 8 days for 270 miles. There is also a potential for the 

 combined application of the canal and the pipeline methods of transportation. 



Features of the Proposed Svstem 



The key feature of the Boylan system is a clear plastic pipeline provided with 

 flotation and anchoring at a fixed elevation within the river-reservoir 

 system. Submerged pumps would be strategically placed along the line to 

 overcome pipe friction losses and provide the energy to accelerate the
