 • operatlorhs shall begin wherrttie first 10 percent of the spring migration has 

 -passed the dam and shall protect-so percent of the spring.migration. Spill shall 

 continue or begin again when the first 10 percent of the summer migrants 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 in a manner consistent with the 90 percent 

 survival objective. The Corps shall develop, in consultation with the fish 

 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, making in-season spill decisions and adjustments in consultation with the 

 fish passage managers. [Source Council s February 1986 decision.]
