Figure 7. Comparison of April-September naturalized stream flow at Saguache Creek <br />with the preceding August-October AMO values. <br />Division 20 <br />On the main stem of the Rio Grande above Del Norte, the long-term naturalized <br />average flow on the river is 20 times that of District 26. However, a look at the overall <br />apparent influence of the HCI variables indicated that the AMO is a notable term to look <br />Figure 8 <br />at in terms of assessing stream flows in the District (see ). The same basic <br />tenants with District 26 existin District 20 as well. As for other HCI variables, the <br />ENSO and NAO values have some ‘non-random’ impact but, not the outright influence <br />the AMO appears to exert on a larger scale. <br />District 35 <br />Although the AMO still appears to be interesting in this District. Very firm <br />relationships appear to exist between the NAO and the observed runoff. Figure 9 shows <br />this relationship in a graphical format. <br />However, it should be noted that the ENSO indices also show a very reasonable <br />relationship with the peak runoff period and should be consulted in refining any seasonal <br />outlook for this District. <br />15 <br />
