• Corps'shaHimplemeni sucn plans until the bypass'anp screening-systems at John Day Dam afe is 

 completed and operating Spill operations shall begin when the first 10 percent of the spring 

 migrants has passed the dam and shall protect 80 percent of the spring migration. Spill 

 shall contmue or isegin again when the first 10 percent of the summer migration has passed 

 the dam, and shall protect 80 percent of the summer migration. Spill shall occur regardless 

 of any impact on firm energy. No spill, however, shall be required after August 15 of each 

 year. 



Before the juvenile passage season, the fish and wildlife agencies and tribes will 

 identify spill criteria:' the spring and summer periods that include 80 percent of the typical 

 spring and summer migrations, the daily hours of spill, and the numbers of fish that will 

 trigger spill operations. These spill criteria will guide spill operations at the project 

 consistent with the 90 percent survival objective. The Corps shall develop, in consultation 

 with the fish and wildlife agencies and tribes, an annual juvenile fish passage plan that is 

 consistent with program standards and incorporates the spill criteria. The Corps shall be 

 responsible for managing and implementing the annual juvenile fish passage plan and shall 

 make in-season spill decisions or adjustments in consultation with the fish passage 

 managers. [Source Council s February 1986 decision ]

 and reported to the Council on study results, shall implement 



(A) A coordinated interim juvenile passage plan which will result in at least a 90 percent
