was intended to provide spill as an interim survival measure until bypass systems 

 were in place at these projeas. 



The Phase II Fish and Wildlife Program Amendments were published by the Council 

 in 1991. These Amendments called for additional volumes to be provided beyond 

 the water budget, to enhance springtime flows, as well as several other actions. 

 Specifically, up to 3 MAF of flow augmentation was to be provided by reducing 

 winter drawdown of Grand Coulee and Arrow reservoirs. In addition, Dworshak's 

 springtime release volume was nearly doubled to 1 . 1 MAF, and the amendments 

 called for summer release volumes from Dworshak. Finally, these amendments 

 called for the four lower Snake River projects to be operating at minimum operating 

 pool to enhance in-river flow velocities, and the operation of John Day at a reduced 

 water level. 



Finally, as a result of the listing of several Snake River salmonid stocks under the 

 Endangered Species Act, and the National Marine Fisheries Service 1993 Biological 

 Opinion, further volumes were provided during the summertime for flow 

 enhancement, and additional spill at Ice Harbor was also provided. Specifically, up 

 to 0.6 MAF of non-Treaty Storage drafl was called for, and added summertime 

 volumes from Dworshak were provided Also, added volumes were provided 

 through the Idaho Water Rental Program. These volumes were all intended to be 

 used for meeting spring/summer flow requirements at Lower Granite and McNary 

 Dams. The springtime McNary flow requirement was similar to that contemplated 

 -but not adopted during the Council's Phase II Amendment process.
