Shadow Mountain Da~ is looated aoross the bed of the <br /> <br /> <br />Colorado River in Section 19, T. 3 N., R. 15 W., 6th Prinoipal Meridian. The <br /> <br /> <br />maximum height of said dam is 18 feet abave the lowest point of foundation <br /> <br />excayation and the orest length of the dam, inoluding the dike extending on <br />the west side of t~ river, is 3149.5 feet. Station 0 I 00 on the Shadow <br />Mountain Dam axis beare N. 180 55' E., a distance of 3862.1 feat from the <br />S. W. Cor. of Sec. 19, T. 3 N.. R. 15 W., 6th Principal Meridian. From <br />Station 0/00 the dam axis bears S. 30000' W., a distance of 520.8 feetl <br />thence along -the axis of the dike S. 060 21' W., 115.1 feet; thence S. 550 OO'W., <br />264.0 feet; thence N. 15000' W., 953.3 feetl thence S. 120 00' W.. 886.20 <br />feet; thence N. 630 30' W., 409.5 feet to Station 30 199.65. said atation <br /> <br />being on the dam axia. <br /> <br />The sources of water supply for Shadow Mountain Lake are the direct <br /> <br />flows of the Colorado River and it. tributaries upstream from Shadow Mountain <br /> <br />Dam and the water pumped from Granby Reservoir heretofore described. <br /> <br />Total above-ground surface capacity of Shadow Mountain Lake only, <br />is 11,354 acre-feet at elevation 8361.0. <br /> <br />"Dead" storage in Shadow Mountain Lake only, is 14.708 acre feet <br />at elevation 8365.0, the elevation of the lip of the intake at <br />Adams Tunnel. <br /> <br />"Active" storage in Shadow Mountain Lake and Grand Lake is 3661 <br />acre feet between elevations 8365.0 and 8361.0 feet. <br /> <br />"Bank" storage in Shadow Mountain Lake is 1300 acre fest. <br /> <br />Total storage in Shadow Mountain Lake and the top two feet of <br />Grand Lake is 19.669 acre feet. <br /> <br />The water impounded in Shadow Mountain Lake and Grand Lake will <br /> <br />flow through the Alva B. Adams Tunnel to the eastern slope or be released <br /> <br />through the spillway or outlet works into the Colorado River. snd thance into <br /> <br /> <br />Granb~' Reservoir and related works. (Sheet 4. Exhibit C). <br /> <br />1. The Alva B. Adams Tunnel (Continentsl Divide Tunnel) (Sheet 4, <br /> <br /> <br />Exhibit C), lesds,from the east shore of Grand Lake. under the Continental <br /> <br />Divide a distsnce of 13.1 miles in s northeasterly direction to Wind River. <br /> <br />a tributary of the Big Thompson River, which is a tributary of the South <br /> <br /> <br />Platte River. Said tunnel has an inside circular diameter of 9' 9", and a <br /> <br />normsl oarrying capacity of 550 s.f. The supply of water for said tunnel is <br /> <br />obtained by means of the dams and collecting systems, ditches. and tributaries <br /> <br />..... <br />2B49 <br /> <br />
