<br /> <br />K-3 EVAPORATION <br /> <br />Average evaporation rates £rom pan records beginning in 1941 through <br />1960 at {Vagon {Vheel Gap are as follows: <br />Evaporation In Inches* <br />kionth Pday June July August September October Total <br />Average through 1960 7.47 8.79 7.40 6.08 5.71 3.32 38.77 <br />No. of years recorded 7 21 21 21 21 8 <br />*The average annual coefficient for conversion from pan to lake <br />evaporation is given as about 70% for the Creede area. The <br />average A1ay-October evaporation is computed to be about 730 <br />of the annual total. <br />An old record made in 1920 through 1926 at a project just west <br />of {Vagon {Vheel Gap, gave the following averages for seven years: <br />Evaporation In Inches <br />• hfonth June July August September <br />North Slope (9601') 4.21 3.41 2.44 1.81 <br />South Slope (9609') 5,82 5.55 4.86 4.50 <br />Average annual pan evaporation within the permit area is estimated <br />to be from 25 to 35 inches per year although no definite conclusions can be <br />abstracted from the limited data available. <br />K-4 TEt•1PERATURE <br />From interpolated information based on records from Creede and IVagon <br />IVheel Gap, the mean daily maximum temperature at the Bulldog P9ountain Operation <br />ranges from +45° to +49°F in January to approximately +g3° to +gg°F in July. <br />It is estimated that the mean daily minimum temperature ranges from -34° to <br />-40oF in January to +27° to +32°F in July. Extremes in temperature may range <br />. fx•om as low as -40° in winter to as high as 85°F in summer. Temperature and <br />wind data from the Creede Station is presented in Table K-1. <br />- 44 - <br />
