Show from material available in the reservoir area. A 50- foot- thick bed of Flagstaff limestone rock is exposed at the damsite and extends upstream from the axis. A quarry site for riprap could likely be located in the reservoir basin area. Concrete aggregate may be obtained from established commercial sources. Dyne Power Unit Dyne Power Unit includes Dyne Aqueduct, Penstock, and Powerplant. The Dyne Aqueduct would convey water from the outlet works of the Sixth Water Dam in Sixth Water Canyon to the Dyne Penstock. The aqueduct would consist of about 9,0^ 5 feet of pressure pipe and l+, 585 feet of pressure tunnel. A surge tank would be installed at the upper end of the penstock. The beginning of the aqueduct line and the inlet portal of the tunnel section may be reached from U. S. Highway 6- 50- 89 through Spanish Fork Canyon, traveling about 20.5 miles via the partially paved Diamond Fork Road, the unpaved Sixth Water mountain access road, and a 3- mile trail downstream from the Sixth Water bridge. The end of the aqueduct and the outlet portal of the tunnel section could also be reached from Spanish Fork Canyon, traveling about 11 and 13 miles, respectively, along the Diamond Fork road and using 1/ 2- mile- long foot trails up the sideslope of Diamond Fork. Prior to construction of the aqueduct, an access road about a mile long would be built from the Diamond Fork road to the outlet portal. Dyne Powerplant would be connected to a switchyard adjacent to the Sixth Water Powerplant by a 138- kv line and would be remotely operated from the Sixth Water Powerplant. Transmission Facilities Bonneville Unit power would be integrated with power from the Colorado River Storage Project ( CRSP) and marketed to potential customers over CRSP's interconnected transmission system. Contracts with several utility companies for interconnection and transmission service could also provide a means of marketing. Project lines would consist of 138- kv lines from the Syar, Sixth Water, and Dyne Powerplants to the Sixth Water Switchyard. Utah Power & Light Company would construct lines from the Sixth Water Switchyard to the Carbon- Hale transmission lines, about 10 miles from the switchyard. A 70 |
