The first Sheridan County Snowpack Report of 2013 shows below normal snowpack for this date despite the addition

of the snows of the last week. The manual snow course data included in this report does not include the snow of the

last 48 hours, and pulls down the overall snowpack averages slightly. Todays Snotel data show on average the

Tongue River Basin is at 83% of normal and the Powder River is just below normal at 96%. These averages are up

14% and 10%, respectively, over the readings from the beginning of this week. Total Precipitation at the Tongue

River drainage Snotel sites is below average at 76%; while total precipitation at the Powder River drainage sites is

98% of average. Manual snow course data included in this report was collected January 25th

through 30th

and Snotel

data in this report is current data as of today, February 1st.

Todays Snotel data from the other major basins in Wyoming report most of the northern and western basins near butslightly below normal. Snows in the past week have improved snowpack Statewide, though the southeast and eastern

border basins of the State are below normal. The southeast basins are well below normal; the highest of which is the

Upper North Platte at 74%, while the Lower North Platte is very low at only 28% of normal, the lowest in the Statetoday.

Snotel data collectors are permanent, remote sites that transmit real-time snow water content and precipitation data

through a west-wide computer network. Daily data from these sites, as well as other water supply-related reports and

products can be accessed through the Waterlink on the Wyoming NRCS Homepage atwww.wy.nrcs.usda.gov.
