12/15/2009 6:53 AM 0.01 0.3 M 7.0 0.45 For some reason the water equivalent of the main core sample was considerably less than what was measured yesterday. A possibility for this is that the core sample has to be scooped out with a spoon considering the fluffiness of the snow. Accuracy may be compromised because of this.

12/23/2009 6:45 AM 0.02 0.3 M 3.5 0.67 Noticed a discrepancy in water equivalency of core sample between yesterday's reading and today's. Yesterday's reading was 0.43 inches and today's reading is 0.67 inches. This may be due to some thicker grass where I took the reading yesterday. I might not have gotten out all of the snow since the grass was of sufficient length that some snow clung to it. Light snow was in progress at time of today's observation.

12/25/2009 8:15 AM 0.00 0.0 M 5.0 1.00 I question the accuracy of this water equivalent of the total snow depth. The sample was taken where there was less grass to hold in the snow, however. I still have to scoop the snow out with a spoon where I put in the cylinder. Merry Christmas to everyone!
12/26/2009 8:40 AM T T M 5.0 0.60 This core sample reading is more consistent with the reading taken during the morning of December 24 than yesterday's core sample. A trace of snow fell during the morning of December 25.

12/30/2009 6:45 AM 0.00 0.0 M 4.5 0.95 There may be an inconsistency in this reading. Most likely it is due to the fact that I have to scoop the snow into the cylinder. Readings in the past generally have been in the 0.70 range.
12/31/2009 8:55 AM 0.00 0.0 M 4.5 0.56 This may be a reading in the other extreme. Again, the sample had to be scooped. I picked up more dead grass with this sample.
1/1/2010 6:55 AM T 0.2 M 4.5 0.91 Light snow in progress at time of observation. Again, I think the water equivalent of total snow depth is extreme, but on the high end. Having to scoop the snow into the cylinder is giving the inaccuracies. I wish the snow would stick to the cylinder when I put it into the snow to get a sample.

Start Date End Date & Time Duration in Days Precipitation Snow Depth Snow Depth SWE Notes
9/13/2009 10/07/2009 7:30 AM 25 2.05 0.0 0.00 This reading may not be entirely accurate. When I left the area on September 13, I did not think that it would be cold enough to snow. So I left the inner cylinder and funnel in the gage. Needless to say, both items are now out and inside. No damage was sustained to the inner cylinder and funnel.
10/22/2009 10/27/2009 6:50 AM 6 T M M It is possible that a bit more than a trace fell at the site. However, I had taken the inner cylinder out of the gage on account of colder weather possibility while I was away from the area. All that was left in the outer cylinder was very little water that could not be measured in the smaller cylinder.
12/17/2009 12/21/2009 6:55 AM 5 T 3.5 0.69 A few drops were in the gage when I emptied it. The snow was more packed than when I measured it last. That may account for the higher number of the core sample than was the case the last time I measured it.
2/25/2010 3/03/2010 7:30 AM 7 0.00 T M There are yet areas of snow where I had shoveled and piled it up on both sides of my driveway. Also, some snowdrifts remain in the sloped back yard. None of those areas were truly representative of the snowdepth measured in the past.
4/17/2010 4/21/2010 7:50 AM 5 0.00 M M If any precipitation fell at the site during my absence it all had evaporated. There was nothing in my gage.
4/24/2010 4/26/2010 7:00 AM 3 0.02 M M There may have been evaporation that took place. Since temperatures still can go below freezing, I have not yet put the smaller cylinder into the larger one outside for precipitation measurement.
