<br />Table 2 shows that the summer flow recommendation of l.65 cfs is available at least 50% of the <br />time from March 15th through August 31 st. Table 2 also shows that the winter flow <br />recommendation of 1.2 cfs is only available at least 50% of the time from September 1 st through <br />January 14th. The winter flow recommendation was further reduced to 1.1 cfs for the time period <br />of January 15th through March 14th based on limited water availability. <br />Precipitation Data <br />Staff reviewed a local precipitation data set located near Gunnison (see Precipitation Data in <br />Appendix C). Table 3 shows the water year and the percent of average precipitation recorded at <br />this site. <br />Table 3: Precipitation Data as a percentage of Average. <br /> Elevation = 7,630 <br /> Lat 38 33 00 <br /> Long 106 55 00 <br /> Year Gunnison <br /> 1955 62 <br /> 1956 352 <br /> 1957 343 <br /> 1958 78 <br /> 1959 38 <br /> 1960 90 <br /> 1961 18 <br /> 1962 88 <br /> 1963 111 <br /> 1964 32 <br /> 1965 73 <br /> 1966 40 <br /> Average 109% <br />It is staffs opinion that the II years of stream-flow data analyzed is representative of slightly <br />above average water-years. <br />Existing Water Right Information <br />Staff has analyzed the water rights tabulation and consulted with the Division Engineer Office <br />(DEO) to identify any potential water availability problems. There are no decreed surface <br />diversions within this reach of stream. According to the DEO, there are two decreed points of <br />diversion located below the proposed ISF reach (Dooley Antelope Irrigation Ditch and Sunshine <br />Irrigation Ditch). Based on this analysis staff has determined that water is available for <br />appropriation on West Antelope Creek, between the headwaters and the Dooley Antelope <br />Irrigation Ditch, to preserve the natural environment to a reasonable degree without limiting or <br />foreclosing the exercise of valid existing water rights. <br /> - 5 - <br />
