Of the two, the physical yield is the <br />more critical factor. As was demonstrated in the foregoing sections, physical <br />yield may be determined in a number of manners including: <br /> <br />1.) analysis of records to determine average and critical year runoff <br />2.) extrapolation of gauged basin data to ungauged basin <br />3.) Ground Water Yield <br /> <br />As determined in the previously referenced Woodward-Clyde study (Appendix C) the <br />estimated physical yield of the non-controlled basin draining to the dam is 900 <br />acre-feet/year during normal runoff and 247 acre-feet/year during low flow <br />periods of drought. This analysis assumes that the Colorado Springs reservoirs <br />control all the runoff flowing to them and that only the 2.5 square mile watershed <br />downstream of the Colorado Springs reservoirs contribute to Victor No.2. This <br />physical yield analysis is conservative in view of the fact that the City may <br />pump to the reservoir from the old Altman dam site and thereby incorporate runoff <br />from the West Beaver Creek Basin. Runoff to the Altman dam pump station from <br />West Beaver Creek is estimated to total 4100 acre-feet/year during an average <br />year and 1523 acre-feet/year during a dry period year. <br /> <br />To document the City's legal water rights yield, a straight line diagram showing <br />locations of and distances between ditches on Beaver Creek has been prepared by <br />others (Appendix C). According to this report, The City of Colorad Springs has <br />water rights superior to the City of Victor, but the City of Victor may effectively <br />claim all water generated between the Colorado Springs' take out point and the <br />Altman dam up to 0.296 cfs by the City's earliest water right (Item a of Table <br />4.6). Additional high priority rights are owned by the City. Although strict <br />admi n i stra tion 0 f the Bea ver Creek wa ter ri ghts system ha s not yet been prac t iced, <br />it is apparent that the City has adequate water rights and physical availability <br />of water to fill and operate the Victor No.2 reservoir. <br /> <br />28 <br />
