The average annual precipitation and the average seasonal pre- 

 cipitation are greater at Moccasin and at Nephi than at Moro. The 

 average evaporation from April to August, inclusive, is 1.01 inches 

 greater at Nephi and 9.74 inches less at Moccasin than at Moro. 

 The ratio of annual precipitation to seasonal evaporation is slightly 

 greater at Moro than at Nephi, but there is a wide difference between 

 the ratios of seasonal precipitation and seasonal evaporation at Moro 

 and the other two stations.
