It is not uncommon for precipitation measured at low elevation stations 
to be less than stream discharge, as rainfall at higher altitudes is 
usually greater than it is at sea level, 
Snowmelt and saturated water- 
sheds are partly responsible for the high percentages which occur in 
May and June.
