<br />Table 2-1. <br /> <br />Average characteristics of the snowpack at 37 snowcourses in the Uinta Mountains on April I, <br />1973-79. All data are from Whaley and Lytton 1979b. <br /> <br /> Elevation Zone (m) <br />Characteristic 2,134-2,438 2,438-2,743 2,743-3,048 3,048-3,353 > 3 , 35 3 <br />No. Snow courses 11 9 11 5 1 <br />Average Elevation/snow course (m) 2, 377 2,593 2 , 864 3,158 3,444 <br />Ave. April 1 '\later Content (cm) 24.3 24.2 31. 3 35.3 31.0 <br />Ave. Maximum A~ril 1 water <br />content (cm) 37.3 45.2 57.9 43.9 <br />Ave. Minimun A~ril 1 water <br />content (cm) 12.2 5.6 14.7 25.9 <br />Ave. April 1 snow density <br />(cm snow/cm water) 3.10 3.24 3.34 3.49 3. 75 <br />Ave. temporal coefficient of (%)2 <br />variation for water content 30.5 41.5 29.7 36. 7 32.8 <br />AVe. spatial coefficient of (%)3 <br />variation for water content 36.9 61.2 45.7 20.8 <br /> <br />IBoth maximum and minimum April 1 water content values represent the long term average for the snow course <br />having the most or the least snow on the average in each elevation category. <br /> <br />2Coefficient of variation is the standard deviation divided by the mean and expressed as a percent. C.V. <br />values were computed for each snow course over years and those values were average by elevation ,zone. <br />These values thus quantify the average year-to-year variation in water content of the snowpack at <br />individual snow courses. <br /> <br />3C.V. values are based on the long-term means and their standard deviations for all courses in an altitudi- <br />nal class. These values quantity the variation among sites within an altitude class. <br /> <br />N <br />N <br /> <br />----------------~-- <br />
