Animas River) essentially flows into the Colorado at Lake Powell in southern Utah. A <br />Figure 10 <br />map of Division 7 and the associated Districts can be found in . <br />Figure 10. Map of Colorado Water Division 7 and its administrative districts <br />A - December to March Precipitation (single season) <br />In summary, the results of the analysis in this Division indicate that ENSO HCI <br />variables are in fact important (and not a surprise given the general research literature <br />available). However, the preliminary results indicate that a number of other factors are <br />involved in the overall response in the basin including Atlantic influences. Given the <br />availability and reliability of data, precipitation analyses were conducted in Districts 30, <br />32, 34 and 71 were conducted with 2, 3, 2 and 2 stations respectively. <br />For some years or individual periods, one station may not have been available <br />therefore only one station would have utilized to calculate basin average precipitation. <br />However, for most Districts and periods analyzed over 90% of all available data was <br />available. It is hoped that having at least two stations in a District does provide a true <br />representation of precipitation with respect to the basin as a whole. <br />All Districts: <br /> The results of this period are similar enough to summarize in one paragraph. For <br />Districts 30, 32 and 71 the well-known ENSO indices do in fact have a reasonable <br />relationship with precipitation in these basins. However, in looking at the charts for each <br />leading period it should be noted that La Nina period have a low probability of <br />19 <br />
