 flow fluctuation limit on weekends and holidays throughout the April 15 to June 15 period, would be 

 as effective m achieving the biological objective of decreasing smolt travel time as the fishery 

 agencies and tnbes proposal Since mamstem Columbia and Snake river flows typically fluctuate 

 from high weekoay flows to low weekend flows The weekend flow fluctuation limit should prevent 

 large drops in flows which, as the fishery agencies and tnbes have indicated, tend to stall the smolt 

 migration. Therefore, the Council believes its amendment would be as effective as the average 

 daily flow proposal m reducing smolt travel time and increasing survival but at a lower cost to the 

 power system Moreover, the Council believes daily flow shaping may be unnecessary because in 

 all or most years non-Water Budget flows during the April 15 through June 15 period should be 

 sufficient, with the weekend flow fluctuation limitation to provide weekly average minimum fishery 

 flows (16USC 839b(h)(6)(C)-)
