Multi -year Relationships: <br />(Upper Colorado- Division 41 Gunnison — Division 5 /Yampa -White <br />Division 6) <br />A final component of this study was the analysis of multi -year results of winter <br />precipitation, spring precipitation and peak seasonal runoff in sections of the Upper <br />Colorado (and major tributaries), the Yampa/White and Gunnison River basins. A map <br />of these basins can be found in Figure 22. For this section, the results will be presented <br />by 1) The 2 -year variable examined and 2) A brief basin -by -basin summary of the <br />relevant HCI values for each variable. <br />Figure 22.

PLATEAU <br />December to March Precipitation: <br />Upper Colorado (River above Kremmling): <br />The only HCI variable that exhibited any reasonable correlation with the 2 -year <br />winter precipitation average was the PDO. A look at the correlation graphs shows that <br />although the negative years are aligned with greater precipitation values they exhibit <br />quite a bit of scatter. However, positive years do strongly tie to average (at best) to <br />below average precipitation in this basin. All other factors (AMO included) did not <br />exhibit much in the way of strong correlations in this area. <br />34 <br />
