1. Project Title: Impact of Drawdown of John Day Reservoir on 

 Level of Predation of Juvenile Salmonids. 



2. Appropriation: Construction General, 96x3122 



3. Authority: Economy Act (31 U.S.C. 1535) , 1982 



4. Purpose and Scope: The proposed activities support the

 effects of the proposed drawdown of John Day Pool on levels of 

 predation on juvenile salmonids. This study will focus on 

 evaluating the existing predation levels and using predictive 

 modeling, estimate effects of the proposed drawdown on predation 

 levels.
