Based <br />on water availability, the winter flow was further reduced to 18 cfs from November 15th to <br />th <br />February 14 . <br /> <br />Precipitation Data <br />Staff reviewed a local precipitation data set from I site located around the Coal Creek Drainage <br />(see Precipitation Data in Appendix C). Table 3 shows the water year and the percent of average <br />precipitation recorded at each site. It is staff's opinion that the 5 years of stream-flow data <br />analyzed is representative of slightly below average water-years. <br /> <br />T bl 3 P <br /> <br />D <br /> <br />fA <br /> <br />a e reClpltatlOn ata as a percentage 0 verage <br /> Elevation = 5690 <br /> Lat 38 52 00 <br /> Long 107 35 00 <br /> Year Paonia ISW <br /> 1977 63% <br /> 1978 No data <br /> 1979 98% <br /> 1980 109% <br /> 1981 105% <br /> Average 94% <br /> <br />Table 3 shows that the 5 years of stream flow data analyzed is representative of slightly below <br />average water years. <br /> <br />- 5 - <br />
