Middle Colorado (River from Kremmling to Glenwood Springs): Most HCI variable are weak and non - usable with only (at best) some minor correlation to the SOI (ENSO) however, this relationship may not be of use. Eagle: The Eagle River basin behaves much like the overall nature of the Upper Colorado basin. The only HCI variable that exhibited any reasonable correlation with the 2 -year winter precipitation average was the PDO. A look at the correlation graphs shows that although the negative years are tied to more precipitation, the values exhibit quite a bit of scatter. However, positive PDO years do strongly tie to average (at best) to below average precipitation in this basin. All other factors (AMO included) did not exhibit much in the way of strong correlation. Roaring Fork: The Roaring Fork basin has a bit more of bi- seasonal influence with regards to winter precipitation. In summary modest connections can be drawn to the ENSO (MEI & SOI — with El Nino years having a slight tendency towards wetter periods) and the AMO (negative years with a tendency towards wet years as well). Gunnison: Most HCI variables are weak and non- usable with only (at best) some minor correlation to the SOI (ENSO) however, this relationship may not be of use for multi- year analysis. Uncompahgre: All of the HCI variables exhibited some modest connection to the basin average precipitation. However, much like the Gunnison basin the results are mixed enough to caution the user to potentially examine cross - variable relationships with regards to this variable. White: The only variable that exhibited some modest connection to HCI variables was the ENSO (primarily the SOI) with some tendency for El Nino to be more wet, which is counterintuitive to single - season relationships. Therefore, caution is urged if one was to plan for precipitation with this variable. 35
