The third phase needed is a short-term testing of a 

 relatively compete system. Short term testing should entail an 

 evaluation of the quality and general well-being of test groups 

 of fish after they have gone through the system- -this is needed 

 before all emigrants of the Snake/Columbia system are committed 

 to using this route to the sea. 



The fourth phase of evaluation will require an assessment of 

 the survivorship to adulthood of smolts that have been delivered 

 down-river using this system relative to presently employed 

 methods or other options. 



This proposal addresses the first two phases. We envision 

 that results of the present proposal should not only meet 

 objectives proposed for those phases but also lead to designs and 

 methods needed for phases three and four as well. In addition, 

 we envision that the assessments that will be necessary to 

 complete phases one and two will lead to answers useful to 

 understanding the nature and potential problems inherent in 

 present fish collection, transport, and bypass systems. In other 

 words, if we are careful in our planning, we should generate data 

 needed to make other decisions as well. Questions not answered 

 relative to presently existing collection/bypass systems may be 

 applicable to the proposed Boylan system as well.
