SECTION 400. ANADROMOUS FISH: 

 DOWNSTREAM MIGRATION - PASSAGE 



403. COUNCIL RESPONSE 



[Add this paragraph at the end of curreni section 403 ] 



In 1986 the Council considered a number of alternatives to the 90 percent survival 

 standard. To provide greater protection for upriver natural and wild runs, the Council 

 extended the spill season to cover all but the first and last 10 percent of the fish migrating 

 during the spring and summer migration periods. The Council determined that spill should 

 be provided regardless of any impacts on firm hydropower. but in no event after August 15 

 of the year. [Source Council's February 1986 aecsion ]
