The project commenced in 1964, as authorized <br />by P.L. 87-590, and is scheduled for completion in 1980. It includes <br />six dams and reservoirs, 18 diversion structures, 10 tunnels, two <br />canals, two powerplants, 52 miles of transmission lines, and two <br />municipal and industrial water delivery conduit systems, requiring <br />39,279 acres of land in Eagle, Pitkin, Lake, Chaffee, Fremont, <br />Pueblo, El Paso, Otero, Cro~ley, Bent, Prowers, and Kiowa Counties, <br />Colorado. <br /> <br />Any structure or right-of-way potentially affects the development <br />of mineral resources in an area. Narrow strips of land for access <br />roads 'and power lines have a minimal effect on potential extraction <br />of mineral reSources because such facilities are readily rerouted <br />and do not preclude resource development. The powerplants and <br />water delivery conduits proposed in this project do not involve <br />lsrge tracts of land and are not situated in areas of significant <br />mineral potential; thus, they represent little potential mineral <br />resource involvement. The proposed diversion dams do not impound <br />much ~ater or involve a large land area, so they also will have <br />little impsct on mineral resources. <br /> <br />The ten diversion tunnels and two canals associated with the <br />Fryingpan-Arkansas Project pose a higher degree of mineral involve- <br />ment. The North- and South-Side Collection System tunnels, the <br />Charles H. ,Boustead Tunnel, the Mt. Elbert Canal, and the Lime Creek <br />Intercept all are locsted in a region of pervasive rock alteration <br /> <br />XI-259 <br />
