Middle Colorado (River from Kremmling to Glenwood Springs): <br />Most HCI variable are weak and non-usable with only (at best) some minor <br />correlation to the SOI (ENSO) however, this relationship may not be of use. <br />Eagle: <br />The Eagle River basin behaves much like the overall nature of the Upper <br />Colorado basin. The only HCI variable that exhibited any reasonable correlation with the <br />2-year winter precipitation average was the PDO. A look at the correlation graphs shows <br />that although the negative years are tied to more precipitation, the values exhibit quite a <br />bit of scatter. However, positive PDO years do strongly tie to average (at best) to below <br />average precipitation in this basin. All other factors (AMO included) did not exhibit <br />much in the way of strong correlation. <br />Roaring Fork: <br />The Roaring Fork basin has a bit more of bi-seasonal influence with regards to <br />winter precipitation. In summary modest connections can be drawn to the ENSO (MEI & <br />SOI – with El Nino years having a slight tendency towards wetter periods) and the AMO <br />(negative years with a tendency towards wet years as well). <br />Gunnison: <br />Most HCI variables are weak and non-usable with only (at best) some minor <br />correlation to the SOI (ENSO) however, this relationship may not be of use for multi- <br />year analysis. <br />Uncompahgre: <br />All of the HCI variables exhibited some modest connection to the basin average <br />precipitation. However, much like the Gunnison basin the results are mixed enough to <br />caution the user to potentially examine cross-variable relationships with regards to this <br />variable. <br />White: <br />The only variable that exhibited some modest connection to HCI variables was <br />the ENSO (primarily the SOI) with some tendency for El Nino to be more wet, which is <br />counterintuitive to single-season relationships.Therefore, caution is urged if one was to <br />plan for precipitation with this variable. <br />36 <br />
