Niwot Ridge LTER Snow Report for January 2002 Snowpack conditions have changed little in the past month: still on the dry side at C1, the South Platte, and the state of Colorado. The lowest snowpacks are in the southwestern part of the state, and the highest are central and north. On 31 January 2002, hand measurements at C1 showed the snowpack to contain 4.25 inches of water, which is 51% of the long term average, and an increase of 6% over a month ago. There was only one other year lower than this, the 1994/95 season (3.9"). The SnoTel records show C1 to have 4.1" (53% of average) snow water equivalent, and 5.7" (68%) cummulative winter precipitation. These percentages suggest that less of the winter precipitation has been sequestered in snowpack, than usual. Statewide conditions, from the NRCS SnoTel records, show the South Platte basin snowpack to be 54% of average, which is the same as a month ago. The highest snowpack percentage is 70% in the Upper Colorado River basin, and the lowest is 48% in the Upper Rio Grande. The snowpack values are virtually the same as the cumulative precipitation in both of these basins, indicating there is just less moisture, rather than a change in snowpack related climate conditions. The manually measured, long term data for C1 follows. Cheers! Mark
