Conservatively assuming lower C-BT and WG quota in second year. <br />5) Demands use a 5-year running average demand distribution, actual 2011 values used if known. <br />6) Assumed that C-BT and WG use is minimized when other water is available, thus usually spills back to user pool for reallocation. <br />WG spills first then C-BT based on pipeline capacity to NWTP (4cfs). <br />7) Untransfered Marshall share include leased shares. Used for Golf Course, Community Park, Ball Fields, and to cover losses, etc.. <br />8) Demands are based on a 5 year running average distribution of demand. <br />9) Assumes that Marshall Lake will fill and spill 2011 and minimal spill in the second year. <br />10) Water Supply Index (WSI) is estimated based on existing conditions and forecasted future conditions. There will be variations in the WSI throughout the hydrological cycle. <br />Calculated based on refined data set see 'WSI' worksheet for more details. <br />WSI =Supply ={Targeted Carryover - Carryover(last)} + SBC Directs + C-BT + WG + Marshall Lake <br />Demand .Demands <br />11_storagePROJCTNS.XLS; Table_Sep119/2/2011 <br />
