Winter 2010 Quota of .5 declared for C-BT (Nov), Supplemental Quota (Apr), Carryover (Jul). <br />WG 2008 in storage, slight chance of spill in 2009. Conservatively assuming lower C-BT and WG quota in second year. <br />5) Demands use a 5-year average demand distribution (06-09), actual 2010 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) Assumes that Marshall Lake will fill and spill in 2010. 1515 AF carried over to meet winter demands Nov. 15-Apr. 15 and minimal spill in the second year. <br />9) 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 /> <br />WSI = ~ =ITaraeted Carrvover - Carrvover(lastH + SBC Directs + C-BT + WG + Marshall Lake <br />Demand Demands <br /> <br />10_storagePROJCTNS.XLS; Table_Feb10 <br /> <br />2/8/2010 <br />
