H. Hydroelectric Reregulating Reservoirs A reregulation reservoir will be located dOvffistream from each hydroelectric power station to provide continuous minimum allowable flow in the Colorado River. Access to these sites is on existing roads. It is anticipated that both drill holes and seismic refraction surveys will be needed along the Dam Axis. These will be located by predetermined field surveys on each site. I. Gore Canyon Hydroelectric Station, Gore Stabilizing Reservoir, and Gore Canyon Power Pipeline The Gore power pipeline connects the Barber Basin Reser- voir on Muddy Creek, with the Gore Stabilizing Reservoir, and follows the 8200 foot contour parallelling Muddy Creek. Gore Stabilizing Reservoir is located approximately 4 miles west of Krerr@ling. The Gore Canyon Power Pipeline also connects the Gore Stabilizing Reservoir and the Gore Canyon Hydroelectric Station, which is located on the Colorado River near the upper end of the Sheephorn Reservoir. Access to these sites generally will have to be on foot or by helicopter. The Gore Stabilizing Reservoir site and the Barber Basin Reservoir site can be reach- ed by existing roads as can various points on the Gore Canyon Power Pipeline. It is anticipated that drill holes and seismic refraction traverses will have to be made along the route of the Gore Canyon Pipeline at predetermined surveyed points. Drill holes and seismic traverses will probably be needed at the Hydro- electric station site and along the axis of the Gore Stabilizing Dam. These also will be located in the field by field surveys. J. Rabbit Ears and Barber Basin System This system is comprised of the Rabbit Ears Dam and Reser- voir, the Barber Basin Dam and Reservoir, the Fish and Walton Creek Collection System, and the Harrison Creek Collection System. The Rabbit Ears Reservoir will be located on Muddy Creek near Rabbit Ears Pass. The Barber Basin Reservoir will be located approximately 4.5 miles downstream of the Rabbit Ears Reservoir on Muddy Creek. The Fish and Water Creek Collec- tion System Route runs north and west from the proposed Rabbit Ears Reservoir. -It is planned that these be water transmission tunnels with shafts and collection facilities at specified points on the system. The Harrison Creek Collection System is located south and west of the Rabbit Ears Reservoir. Small collection and diversion facilities will transport water into a tributary of Muddy Creek. Access to these facility sites will probably be made on foot or by helicopter. It is planned that drill holes and seismic refraction traverses be made along the route of the tunnels, and at diversion facility sites. The location of these seismic traverses and drill holes will be located in the field by survey. The dam sites are accessible by existing county roads. -10- r ,.
