':".2;'

The elevation of C5 is 10,600 feet. Data from the charts was hand read

from July 1, 1965 to September 6, 1975. The data from September 7, 1975

to October 6, 1977 was digitized. Part of the missing data could be

.

estimated using regression-correlation procedures. C5 was correlated with

Cl, C3, C7. The following equations were obtained:

Times during which the clock was stopped and the precipitation which fell

in that time period are given in the following chart:

Clock Stopped Chart Off Total Precipitation (inches)
- 751017 751028 .55
751031 751107 .45
761127 770422 6.73
770503 770505 .01
770516 770524 .04
770604 770615 1.87

This shows that in the time period from October 17, 1975 to June 15, 1977

that the clock was stopped for a total of 187 days. Of these 187 days, only

17 days could be estimated for precipitation values.

Average annual precipitation, using the time period from July 1965 to

October 1977 is 20.38 inches per year. Average annual precipitation using

~ the period from July 1965 to October 1975 is 21.34 inches per year.
