<br />-- <br /> <br />PROJECT PLAN <br /> <br />Glen Canyon Dam will be a gra-lity arch concrete structure that will <br />rise 700 feet above its foundation and 573 feet above the river. It will <br />have a crest length of 1,500 feet. The dam will be the fourth highest in <br />the world and second in height or>~y to Hoover Dam in the United States. <br />The reservoir will have a capacity of 28,040,000 acre-feet. '\t!hen full, <br />1 t 'nll cover about 163,000 acres and will extend 186 miles up the Colo- <br />rado River, nearly to the mouth of Green Hi ver, and 71 miles upstream on <br />the tributary San Juan River. About 6,535,000 acre-feet of the reservoir <br />capacity will be inactive and will be useful for sediment accumula.tion, <br />to protect fish, and to provide the pmler head at the dam. A powerplant <br />and swi tchyard will be constructed at the dam. The powerplant will include <br />eight generating units with a total install~d caIlaci ty of 900,000 kilowatts. <br />An access road and a bridge across the canyon about 900 feet downstream <br />from the dam site will be constructed to Federal bighl1ay sta.ndards. <br /> <br />Heasures will be taken to protect the Rainbow Bridge National Monu- <br />ment at one of the side bays of the Glen Canyon Reservoir. <br /> <br />Flaming Gorge unit <br /> <br />e <br /> <br />Flaming Gorge Dam will be on the Green River, a major tributary of <br />the Colorado, in northeastern Utah about 6 mil.es south and 20 miles west <br />of the corner com.on to Utah, Wyoming, and Col.orado. The dam will be a <br />concrete thin arch structure rising about 495 feet above its foundation <br />and about 445 feet above the river. It will have a crest length of 1,270 <br />feet. The reservoir will have a total capacity of about 3,930,000 acre- <br />feet and an area of about 42,000 acres. It will extend upstream 93 miles, <br />nearly to the town of Green River, Wyo. About 330,000 acre-feet of the <br />reservoir capacity will be inactive. The pmverplant at the dam will con- <br />sist of three generating units with a total installed capacity of 108,000 <br />kilowatts. A swi tchyard will be constructed nearby. <br /> <br />Navajo unit <br /> <br />Navajo Dam will be constructed on the San Juan River in New Mexico <br />about 34 miles east of Farmington. The dam will be an earth-fill struc- <br />ture about ;85 feet high above the river and nearly 3,800 feet long at <br />the crest. Navajo Reservoir will provide water for the Navajo Indian irri- <br />gation project, when that project is authorized and constructed, and also <br />will provide water directly or indirectly for other potential projects in <br />New Mexico. The reservoir will have a total capacity of 1,700,000 acre- <br />feet and an inactive capacity of 672,000 ~cre-feet, of which about 70,000 <br />acre-feet will be dead storage. The reservoir when full ,.,ill inundate <br />15,300 acres and will extend approximately 34 miles up the San Juan River. <br />Although the outlet ",orks are such that a po",erplant could be insta.lled at <br />a later date, no powerplant is included. in the present plan. Recreational <br />facilities will be provided at the reservoir. <br /> <br />e <br /> <br />5 <br />
