Average daily usage for the period 1979 through September 1986 are shown <br />on Table 4.1. From this table, the average daily use of water for this period is <br />about 232,000 gallons per day or 0.36 cfs. This volume further translates to <br />about 260 acre-feet of water use annually. The Bull Hill flow meter simply totals <br />flows and therefore peak hourly, daily, and weekly flows are not known. <br /> <br />Using the projected populations developed in Chapter 3, and based on the average <br />monthly water use from Table 4.1, the future water use can be estimated. Table 4.2 <br />shows the project water use requirements in acre-feet per month, and constant flow <br />required in cfs to provide the monthly volume. <br /> <br />Surface Water Supply <br /> <br />Except for periodic flow measurements through a 36-inch flume during the period <br />1938 through 1942 there are no historic flow records available for the stream <br />feeding the city's water system. The available measurements for the fume which was <br />located just above the diversion point for dividing flows to Victor No.2 Dam and <br />Bison Reservoir are sketchy at best and the accuracy of the measurements and <br />cal ibration of the flume are questionable. These measurements were occasional <br />depth readings taken on the flume during May through October. Assuming that the <br />flume would have similar characteristics as a Parshall Flume, the average flow <br />recorded during this time is 3.96 cfs. This data is shown on Table 4.3. <br /> <br />A second approach to the analysis of water supply availabil ity is based on a <br />correlation of stream flow records of stations deemed to have similar runoff <br />characteristics. This approach was taken in a June 18, 1976 study prepared by <br />Woodward-Clyde Consultants for the City of Victor. This study, reproduced in <br />Appendix C, and entitled "Water Rights Evaluation, City of Victor, Colorado" <br />indicated that the upper half of the drainage basin leading to Victor Reservoir <br />NO.2 is effectively controlled by two reservoirs owned by Colorado Springs. <br />These reservoirs are designated as Reservoirs No.7 and 8, and serve to collect <br />and convey water out of the basin via the Strickler Tunnel. The correlation <br />study indicated that the average annual runoff from the 3.6 square mile watershed <br />supplying the Colorado Springs reservoirs would approximate 1,200 acre-feet. <br /> <br />22 <br />
