Winter 2011 Quota of .5 declared for C-BT (Nov), Supplemental Quota (Apr), Carryover (Jul). <br />WG 2010 in storage, good chance of spill in 2011. Conservatively assuming lower C-BT and WG quota in second year. <br />5) Demands use a 5-year average demand distribution (01-10), 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) Assumes that Marshall Lake will fill and spill in 2011. 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 />WSI =Supply ={Targeted Carryover - Carryover(last)} + SBC Directs + C-BT + WG + Marshall Lake <br />Demand .Demands <br />11_storagePROJCTNS.XLS; Table_Feb112/24/2011 <br />
