| Relation | Central Utah Project; Western Waters Digital Library; operation of the no action alternative at monks hollow these two sources would be involved in the operation of the no action alternative the third source is the natural flow of spanish fork river 16.2 162 162 water delivery under the no action alternative an average of 158300 acre feet per year of SVP and bonneville unit water would be released from strawberry reservoir and conveyed to the spanish fork river for irrigation and utah lake water supply this includes 61500 acre feet of SVP water and 96800 acre feet of bonneville unit water for delivery to utah lake for supplemental irrigation mai m&i water for exchange for use of southern utah county wells and springs exchange to jordanelle Jor danelle reservoir and to meet minimum strearnflow streamflow stream flow requirements in sixth water creek and diamond fork creek natural streaniflow streamflow stream flow is not included in these figures delivery of water to maintain the minimum streamflows stream flows in sixth water creek from strawberry tunnel to sixth water aqueduct and diamond fork creek below monks hollow would receive first priority and would govern release of water to the creek the rest of the water needed for SVP irrigation demand supplemental irrigation and mai m&i exchanges would flow through diamond fork pipeline until it is operating at maximum capacity of 560 cfs cs up to 388 cfs cs would be released to the creek from three forks dam under normal operations including the minimum strearnflows streamflows stream flows required below monks hollow and additional water in excess of the diamond fork pipeline when it would convey capacity flows this released water would flow through diamond fork creek to spanish fork river the 14700 acre feet per year of supplemental irrigation water would be diverted from spanish fork river as a supplemental irrigation supply for the 47800 acres of presently irrigated lands in the spanish fork area these lands could include non SWUA lands served by the high line east bench salem south field mill race and lake shore canals as well as the mapleton lateral this supplemental irrigation water would be diverted from the spanish fork river at existing diversion facilities and conveyed to farms through existing distribution facilities no new facilities would be constructed and no water would be delivered to juab county lands requested to receive bonneville unit supplemental irrigation water that have not already been certified arable by the secretary of the interior would need to be certified before receiving bonneville unit irrigation water the total amount of the transbasin trans basin diversion under the no action alternative would be 96800 acre feet ofthis orthis of this 96800 acre feet 14700 acre feet would be delivered to south utah county for supplemental irrigation about 1590 acre feet would be delivered for mai mal use in south utah county A net of 80500 acre feet would be directly delivered to utah lake the difference between the 80500 acre feet and the provo river depletion of 98500 acre feet would be made up from return flows 13000 acre feet from mai m&i use in northern utah county 4200 acre feet from the supplemental irrigation deliveries and 800 acre feet from the mai m&i water delivered to south utah county 162.1 1621 normal operation syar tunnel and sixth water aqueduct would convey about 141200 acre feet per year see table 114 1 14 maximum flow capacity of syar tunnel and sixth water aqueduct is 800 cfs cs when strawberry reservoir is full and 660 cfs cs when the reservoir is at its operational minimum under the water operation maximum flow of syar tunnel would range from 600 cfs efs es to 0 cs cfs based on the 44 year record used to develop system operations the hydrology for operation of the no action alternative was developed by CUWCD 1998c using the methodology described in the draft hydrology & water resources technical report CUWCD 1998c page 31 3 1 detailed tables supporting operation of the no action alternative in the hydrology and water resources technical 153 1 53 diamond fork system FSFEIS FS FEIS |
