Show flows in excess of 600 second- feet and convey them around Springville and subsequently into the Provo Bay Bypass for delivery into Utah Lake. ( 6) The Currant Creek Road would be located on the east side of Currant Creek Reservoir, rather than the west side. The road relocation, although 3 1/ 2 miles longer, was recommended by the Forest Service to serve the recreation needs more adequately. ( 7) The Rock Creek Road and the portion of Currant Creek Road located in the National Forest would be constructed to a higher design standard, with a 24- foot surface, rather than an 18- foot surface. ( 8) The active capacity of Upper Stillwater Reservoir would be 31,600 acre- feet, instead of the 25,000 acre- feet proposed originally, to provide minimum fishery flows. Upper Stillwater Dam would be a rockfill structure with an asphaltic concrete membrane, rather than the rolled earth- and rock- fill structure originally planned. This change in plan was made on the basis of a favorable cost comparison completed in January 1973 and as a result of a suggestion made by the Forest Service and others. This change would eliminate or greatly reduce the need for embankment material from a borrow area below the dam which would conflict with potential recreational development. ( 9) The proposed alinements of Hades and Rhodes Tunnels have been changed ( 1) to move the inlet portal of Hades Tunnel away from the rocky cliff and effect a better connection with the North Fork Siphon, ( 2) to eliminate most of the Wolf Creek Pipeline, ( 3) to relocate both portals of Rhodes Tunnel to less conspicuous sites, ( 4) to reduce the amount of access roads required, and ( 5) to facilitate disposal of the tunnel spoil. These changes were made as a result of field inspection with the Forest Service and others. ( 10) The Starvation Dam was located further downstream than was planned originally, resulting in a decrease in the length of feeder canal facilities required. ( 11) Other changes, such as relocation of various features of the Dyne Powerplant system and the Wasatch Aqueduct, are being considered. 15 |
