<br /> <br />" <br /> <br />SIXTH WATER FLOW THROUGH PLAN <br /> <br />This alternative of the Diamond Fork Power System was <br />described in the 1964 Definite Plan Report and 1973 Bon- <br />neville Unit Environmental Impact Statement. It is shown in <br />plan view in Figure No.1, which summarizes the sizes otthe <br />various features. In this alternative, water flows from the <br />enlarged Strawberry Reservoir through Syar Tunnel to Fifth <br />Water Ridge where it passes through Syar Powerplant into <br />Syar Reservoir. From Syar Reservoir, the water drops down <br />into Sixth Water Canyon, by flowing through the Corona <br />Aqueduct, through Sixth Water Powerplant and into Sixth <br />Water Reservoir. The Dyne Aqueduct then carries the water <br />along Tanner Ridge to the Dyne Powerplant located near <br /> <br />Figure No. 1 <br /> <br />SIXTH WATER FLOW <br />THROUGH ALTERNATIVE <br /> <br />II, <br />~ <br />t <br /> <br />Sixth Water Res. <br /> <br />Dyne Aqueduct <br /> <br />Dyne Power Plont <br /> <br />For\\. <br /> <br />.

At this point the flow is divided. The portion of <br />water destined for southern Uteh and Juab Counties and the <br />Sevier River Basin is conveyed in the Wasatch Aqueduct <br />down Diamond Fork Canyon to Spanish Fork Canyon. From <br />the contluence the Wasatch Aqueduct continues on, but not <br />as part of the Diamond Fork Power System. The portion of <br />water going to Utah County and Utah Lake is released into <br />Diamond Fork River and flows into Hayes Reservoir. Hayes <br />Dam is located about one-half mile upstream f<Gm the con- <br />fluence of the Diamond Fork and Spanish Fork Rivers. <br /> <br /> <br />~ <br />'" <br />~ <br />...'" <br />~~ <br />,,~ <br />~ <br />~Sya' Tunnel <br />~ <br />.,:- <br />~ <br />.,; <br />~ <br />...-.-9-;;' Syar Power Pion' <br />~~ <br />~~ <br />~ <br /> <br />Feature Size <br /> <br />Syar Tunnel - 8 foot diameter, 6.5 miles long <br />Syar Powerplant - 10.5 megawatts <br />Syar Reservoir - 32 acres, 930 acre-feet <br />Syar Dam - 88 feet high <br />Corona Aqueduct - 12.5 foot diameter, 1 mile long <br />Sixth Water Powerplant - 90 megawatts <br />Sixth Water Reservoir - 35 acres, 1020 acre-feet <br /> <br />Sixth Water Dam - 150 feet high <br />Dyne Aqueduct - 8.5 foot diameter, 2.5 miles long <br />Dyne Powerplant - 33 megawatts <br />Wasatch Aqueduct - 6 foot diameter, 9.5 miles <br />Hayes Reservoir - 680 acres, 51,500 acre-feet <br />Hayes Dam - 200 feet high <br />
