CODOS has now observed eleven seasons of dust-enhanced snowmelt runoff behavior throughout the Colorado mountains (WY 2006-2016).  Hydrographs at headwater stream gauges have been evaluated and classified within the framework of this dust enhanced snowmelt runoff space utilizing a 3 x 3 x 3 cell matrix corresponding to general characterizations of SWE, dust intensity, and spring weather, as shown in this figure.

Water Years 2006-2016 have been analyzed and classified for the following stream gauges associated with the Wolf Creek Pass CODOS site:
