will resting areas be needed? 



Velocity in P.L. may determine this in part 

 Ponds or net pens or other impoundments could be 

 added 



Will debris be a problem in the line? 



Screens would keep out the larger materials 

 Periodic automatic flushes from the bottom of the 

 P.L. would carry out fine materials 

 Flush out ports would be screen for fish 



What if the P.L. breaks - escape of Smolts? 



Repair by dive teams would replace pumps, pump 

 modules or line sections 



Smolts lost to the reservoir will continue on to be 

 picked up at the dam screen collection system 

 already in place 



What of collection systems? 



The P.L. would capitalize on existing and improved 

 collection systems at dams and perhaps a new 

 Lewiston vie collector 



What measures will be taken to insure the proper water 

 mix? 



The majority of water will be as found at the 

 entrance terminal, just below the dams{s) 



Alteration of this mix could be accomplished at each 

 pump module by adding and subtracting water. 



What of food requirements of the Smolts in transit? 



If there is a food requirement it could be added at 

 the p\imp modules 



Test loop operations could show if food is needed 

 for various expected trip durations
