<br />001360 <br /> <br /> <br />(d) In the region of the following-named cities and <br />towns: Grand Canyon area north of Peach Springs. <br /> <br />7. Lands of the United States whioh will be affeoted are located in <br /> <br />Speoial Reservation along the Colorado River, <br />Hualpai Indian Reservation and a small part of <br />the Publio Domain. <br /> <br /> <br />8. The proposod soheme of development for the projeot is as follows: <br /> <br />The dam-site is about 10-1/2 miles below the mouth <br />of Di~ond Crook a short distance below Gniess Canyon. <br />The oross-section of the d~-site is narrow. the <br />width of' tho rivor being only 150'. A d~ to raise <br />the _tel' 570' would have a orest length of 870'. The <br />dam would be construotod of either conorete or of <br />Cyolopean masonry f~ the lime-stone oliffs nearby. <br />Spillways will be tunnels about lpO' long spilling <br />into the side-canyon an tho left, known as Spillway <br />Canyon. The dam so built would form 0. lake 78 miles <br />long with a surfaoe area of' approximately 8,500 aores <br />and would have a oapacity of approrlmately 2.500.000 <br />aore feet. Sinoe there are no important improvoments <br />in this part of the oanyon tho damage would be negligible. <br /> <br />Estimated power available 90% of the time is 330.000 HP, <br />50% of the time is 500.000 HP. Installed oapaoity <br />800.000 HP with provision for the installation of an <br />additional 300.000 HP with upstream storage development <br />and regulation. <br /> <br />9. The proposed use or markat for the power to be developed is as <br />follows: <br /> <br />Power from the Bridge Canyon Projeot would be used <br />to develop the natural resources of northeastern <br />Arizona and southwestern Utah. These areas oonttlin <br />valuable mineral resources, whioh have bean un- <br />developed owing to the lack of' chetlp power. The <br />Santa Fe railroad comos within 20 miles of this <br />power site and would be a potential market for <br />power developed horo. Electre.fication of this <br />railroad from Holbrook to Kingman would be feasible <br />and ecancmical. owing to tho fact that heavy grades <br />exist in this portion of the road. <br /> <br /> <br />-2- <br />
