Dust Enhanced Runoff Classification
Dust Enhanced Runoff Classification
CODOS has now observed eleven seasons of dust-enhanced snowmelt runoff behavior throughout the Colorado mountains (WY 2006-2018). 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.
A conceptual dust enhanced snowmelt runoff model integrating the interactions of March 1 SWE, dust intensity, and spring precipitation.
Water Years 2006-2018 have been analyzed and classified for the following stream gauges associated with the Spring Creek Pass CODOS site:
Rio Grande near Del Norte (pdf)Lake Fork at Gateview (pdf)
For a detailed discussion of this approach, see the state-wide Dust Enhanced Runoff Classification section.

For each Snotel site below, the first nine plots show a single Water Year's SWE relative to the site's historical record (1971 - current). The last two plots compare SWE and Dust on Snow events for two consecutive years. The shaded bands represent non-exceedence percentiles in the following order (from the bottom up):
Minimum - 10th percentile (dark gray)
10th - 30th percentiles (medium gray)
30th - 70th percentiles (light gray) with 50% trace in the middle
70th - 90th percentiles (medium gray)
90th - maximum (dark gray)

Analyses of Slumgullion and Beartown Snotel data for Water Years 2006-2017 snowmelt seasons showing date and quantity of peak SWE, days from peak SWE to “snow all gone” (SAG), total additional precipitation after the date of peak SWE, an “adjusted” mean daily rate of snowmelt adding the additional precipitation to the peak SWE total, the maximum five-day moving average of daily melt, and the mean air temperature over the entire snowmelt period, from peak SWE to SAG. POR refers to each snotel's entire period of record.
