<br />Chapman Gulch Estimated Stream Flow <br /> <br />. <br /> <br />J!! <br />u <br /> <br />5 <br />4 <br />3 <br />2 <br />1 <br />o <br /> <br /> <br />~~ ~ %;'?

The summer/winter recommendation was reduced to 0.3 <br />cfs from July 15th through May 14th due to water availability concerns. <br /> <br />. <br /> <br />Precipitation Data <br />Staff reviewed local precipitation data sets from 2 different sites located around the Chapman <br />Gulch Drainage (see Precipitation Data in Appendix C). These sites include Telluride (1900- <br />1999) and Ames (1914-1986). Table 3 shows the water year and the percent of average <br />precipitation recorded at each site. <br /> <br />Table 3: Precipitation Data as a percentage of Average. <br /> <br />Water Year Telluride Ames <br />1959 96% 88 % <br />1960 90% 91 % <br />1961 127 % 109 % <br />1962 85 % 88 % <br />1963 117% 97% <br />1964 117% 81 % <br />1965 139% 139% <br /> <br />Table 3 shows a slight variation of precipitation between the two relatively close precipitation <br />sites. It is staff's opinion that the seven years of stream-flow data analyzed is representative of <br />average to slightly above average water-years. <br /> <br />. <br /> <br />Existing Water Right Information <br /> <br />Staff has analyzed the water rights tabulation and consulted with the Division Engineer Office to <br />identify any potential water availability problems. There are no decreed surface diversions within <br />this reach of stream. Based on this analysis staff has determined that water is available for <br />appropriation on Chapman Gulch, from its headwaters to the confluence with the Howard's Fork <br /> <br />- 5 - <br />
