<br />~ <br />Cj <br />C'J <br />N <br />" 11 <br />c <br /> <br />Tunnel is 3.8 miles long with a design capacity of 600 cfs. however. because <br />of structural problems the tunnels delivery capacity is restricted to 460 cfs. <br />With construction of Soldier Creek Dam. and enlarged Strawberry Reservoir. <br />storage facilities and most of the means of conveyance were incorporated into <br />the Strawberry Aqueduct and Collection System. Water stored in the enlarged <br />Strawberry Reservoir and owned by the Strawberry Valley Project is controlled <br />by the Strawberry Water Users Association and will be delivered through the <br />Syar Tunnel. <br /> <br />An average annual diversion of 61.500 acre-feet presently occurs through the <br />Syar Tunnel. A joint proposal for the right to develop hydroelectric power <br />was submitted by Central Utah Water Conservancy District and Strawberry Water <br />Users Association. In 1996 their proposal was accepted by the Department of <br />the Interior and they were granted the right to negotiate a lease of power <br />privilege within the Diamond Fork area in 1996. Consultation needs to be <br />completed on that Federal action. <br /> <br />The Central Utah Water Conservancy District operates and controls annual <br />operations of project facilities under contract with the Bureau of <br />Reclamation: thus. depletions associated therewith are subject to section 7 <br />consultation. <br /> <br />Provo River Proiect. Duchesne Tunnel <br /> <br />The Provo River Project provides a supplemental water supply for irrigation <br />and for communities along the Wasatch Front. Bonneville Basin. Part of the <br />water supply is supplied by the Duchesne River. Features of the collection <br />system involving the Duchesne River include the Duchesne Diversion Dam and the <br />Duchesne Tunnel. The Duchesne Diversion Dam is on the North Fork of the <br />Duchesne River. The Duchesne Tunnel conveys water from the diversion dam to <br />the Provo River drainage basin. The tunnel is 6 miles long and has a capacity <br />of 600 cfs. Construction and lining of the Duchesne Tunnel were co~pleted in <br />1952. Effects of this project are addressed both in this opinion and in the <br />Provo River operations opinion. <br /> <br />At full demand. an average annual depletion of 31.700 AF will occur through <br />the Duchesne Tunnel. Operation of the Provo River Project. of which the <br />Duchesne Tunnel is a feature. requires contractual authorization by the Bureau <br />of Reclamation and is therefore subject to section 7 consultation. <br /> <br />Central Utah Proiect - Bonneville Unit <br />
