Analysis of Design and Operation of Selective Withdrawal Modifications of Hungry Horse Dam

Du Xiaohu,Li Yuejun(HydroChina Corporation,Beijing 100120)  
The Hungry Horse dam has a Selective Withdrawal System(SWS)composed by 3 semi-cylindrical gates,which can effectively increase the water temperature of downstream channel and reduce the great water temperature fluctuation.The improvement of water temperature and quality in the downstream channel is helpful to the rehabilitation of hydrobiology population including zooplankton,insects,and fish productivity.Local trout quantity and size has been increased greatly.SWS operation is flexible except that submergence depth and head loss is higher than design value.Some disadvantages such as the reduction of biological production in reservoir,high water hammer load on the gate,annual maintenance cost,etc.,are the unfavorable factors of SWS gate structure.
