<br />00 <br />,.... <br />,~ , <br /> <br />C'J <br />CJ <br /> <br />1:_ <br /> <br />14 <br /> <br />Water Conservancy District is studying other alternatives. . The Diamond Fork <br />Pipeline is under construction. <br /> <br />All Diamond Fork facilities were built with the commitment to divert 101.900 <br />acre-feet to the Bonneville Basin. However. if the Spanish Fork-Nephi Project <br />No Action Alternative is selected in a future Record of Decision. the' <br />transbasin diversion would be reduced to 96.800 acre-feet. The Final <br />Supplement to the Diamond Fork Final Environmental Impact Statement and the <br />July 1990 Record of Decision commit to a complete evaluation and comparison of <br />impacts associated with the Spanish Fork-Nephi system on resources of <br />Strawberry Reservoir. Utah Lake. the Jordan River. and Utah Valley streams. <br />This impact analysis would be included in the Spanish Fork-Nephi draft <br />Environmental Impact Statement. <br /> <br />Spanish Fork Canvon-Nephi Irriaation Svstem <br /> <br />The Spanish Fork Canyon-Nephi Irrigation System was formerly known as the <br />Irrigation and Drainage System and begins at the confluence of Diamond Fork <br />Creek and the Spanish Fork River. The system includes mainstem conveyance <br />facilities to deliver 101,900 acre-feet of water and a transbasin diversion <br />from the Colorado River Basin to the Great Basin. The system will deliver <br />68,400 acre-feet for irrigation use in southern Utah and eastern Juab <br />counties: 11.200 acre-feet for municipal and industrial uses in southern Utah <br />county: and 22,300 acre-feet to Utah Lake for the Jordanelle exchange. The <br />water supply will be provided through transbasin diversion from Strawberry <br />Reservoir through the Diamond Fork System to the Spanish Fork-Nephi System. <br />The Spanish Fork-Nephi System's Main Conveyance Aqueduct will connect directly <br />to the Diamond Fork Pipeline and will have a maximum flow capacity of 560 cfs. <br /> <br />The Spanish Fork-Nephi System Draft Environmental Impact Statement has been <br />released for review and comments. <br /> <br />Central Utah Proiect - Uinta Basin Replacement Proiect <br /> <br />Upalco Unit <br /> <br />The Upalco Unit of the Uinta Basin Replacement Project would develop flows of <br />the Lake Fork and Yellowstone Rivers. with minor contributions from other <br />small streams for irrigation of Indian and secondary lands and municipal and <br />industrial water uses. Project irrigation water would be made available from <br />regulation of high flows of the Yellowstone River. from savings of seepage <br />losses through rehabilitation of existing canals. and from retiring marginal <br />
