I 'I , II I I I II I II II II i II I I II I II II II study which specifically addressed the population of the area south of the Colorado River. The capacity analysis presented in that study concluded that a much smaller portion of the South Rifle area (260,8 acres) has a potential residential capacity of 3,946 persons. This estimate is in good agreement with the ultimate residential population of 4,800 adopted for this study for a larger area. The number of residential units planned for Rifle Village South and an assumed density of residential units for the rest of the project area were multiplied by an estimated average number of occupants per dwelling unit of 2.75 to obtain the total projected population for the area. SURFACE WATER SUPPLY The source of the raw water supply for the South Rifle Division would be from the flows of the Colorado River available under a portion of the West Divide Project direct diversion rights on the Crystal River which would be transferred to an intake at a river pumping station, In order of magnitude, the required diversions for the South Rifle Division are insignificant when compared to the flow of the Colorado River at Rifle. The estimated peak day diversion demand by year 2025 is 4 cfs which is less than 1/900th of the average flow in the Colorado River at Rifle. There are no USGS gaging stations on the Colorado River in the vicinity of Rifle; therefore, evaluations were based on the recorded streamflows at Glenwood Springs as shown in Table IV-5. The streamflows at Rifle would be larger than the recorded flows below Glenwood Springs by approximately the amount of the inflows from Canyon, Elk, Garfield, Divide, and Mamm Creeks. The values given in Table IV-5 are the sum of the recorded flows at USGS gaging stations 9-0725 IV-6
