There are many snow and precipitation monitoring stations in the Colorado mountains. Find the map at www.wcc.nrcs.usda.gov/snotel/Colorado/colorado.html
On the map, look at the bottom center for the two blue dots close together. Click on the right one to bring up www.wcc.nrcs.usda.gov/nwcc/site?sitenum=857&state=co
This is the Whiskey Creek snotel site (pronunciation is up to you). Now, look at the table in the center of the page. Find the Current Water Year column, and click on "daily graph" to get to www.wcc.nrcs.usda.gov/cgibin/wygraph-multi.pl?state=CO&wateryear=2010&stationidname=05M14S-WHISKEY+CK
This graph contains four plotted lines: the yellow line is the average total precipitation (inches of water, not snow) for the years 1971 to 2000. [We have calender years, fiscal years, and now water years. It appears the 2010 water year runs from September 2009 through August, 2010.] The light blue line shows the average water equivalent in the snow pack for the past 30 years. The dark blue line is this year's snow water equivalent, and the red line is this year's total water equivalent precipitation to date.
