The Council used several principles in developing its policy on resident fish 

 substitutions. First, it concluded that mitigation in blocked areas is appropriate where 

 salmon and steelhead were affected by the development and operation of the hydroelectric 

 projects. Second, in order to treat the Columbia Ri\^rand its tributaries as a system, some 

 level of substitution will be reasonable for lost salmon and steelhead in areas where In-kind 

 mitigation cannot occur. Finally, some flexibility in approach is needed to develop a 

 program that complements activities of the fish and wildlife agencies and tribes and is 

 based on the best available scientific knowledge. 



Applying these principles, the Council has determined that it will approve resident fish 

 substitutions projects in the blocked areas above Chief Joseph and Hells Canyon dams 

 first. The Council will consider projects in other blocked parts of the basin later, when the 

 level of performance or accomplishment in anadromous fish restoration and in upper basin 

 substitutions is known. In addition, resident fish substitution projects must: 



(a) Incorporate adaptive management principles (see section 1503); 



(b) Complement activities of fish and wildlife agencies and tribes: 



(c) Address unmitigated losses of salmon and steelhead attributable to development or 

 operation of hydropower projects: 



(d) Appear likely to achieve significant biological results: 



(e) Avoid conflict with anadromous fish:
