navigation locks and even fish passage facili- 

 ties can operate, the dams and fish passage 

 facilities could require modifications. 



We call on the Corps of Engineers, other 

 agencies and Indian tribes to help us evaluate 

 the effectiveness of using this degree of draw- 

 down in combination with other flow 

 measures. This involves preparing plans on 



drawdown design, operations, biological im- 

 pacts and mitigation of economic 

 consequences. The Corps is developing these 

 plans, in consultation with the Bonneville ' 

 Power Administration, the Bureau of Recla- 

 mation and our Council. These plans are 

 expected to be completed in 1994.

ACTIONS 



a''t the Dams 



3tore more water in the winter 

 and release it in the spring and 

 summer to boost flows when 

 juvenile salmon migrate to the 

 ocean. j 



Screens and Bypass ' 

 Screen turbines and improve 

 bypass systems that carry 

 young salmon past dams. 



Minimum Operating Pools 

 Lower reservoirs to the mini- 

 mum levels at which navigation 

 locks will still operate, to make 

 the current faster for salmon 

 migration. 



t ransportation 



Improve barge transportation of 

 juvenile fish past Snake and 

 Columbia river dams. 



Spill, 



Move young salmon down- 

 stream by spilling them over 

 dams, until adequate turbine 

 screens are in place. 



Control Predators 



Reduce the number of salmon 

 predators.
