Start Date End Date & Time Duration in Days Precipitation Snow Depth Snow Depth SWE Notes
10/4/2010 10/30/2010 10:00 AM 27 2.73 2.0 M This accumulation is to be compared with 2.52" I've calculated from the reports nearby over the same time period. I'm amazed that it is not lots lower than that sum. Much of it was as snow and I still had left the funnel in the top. This cut evaporation, no doubt, but the snow must have piled and somehow not blown off.
