 triPes will prescripe the method for determining smolt survival at this project Spill 

 operations shall begin when the first 10 percent of the spring migration has 

 passed the dam and shall protect 80 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 

 number 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 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.
