As has already been stated, observations covering a number of years in 
the vicinity of Fresno show that the water table averages were higher 
during June than at any other time of the year. 
Figure 13 shows results similar to those of the previous ones. The 
readings on July 19 were taken at the end of a two-day period, in which 
the pump was idle, and those on the 26th show the effect of the irriga¬ 
tion which was taking place on the fields north of the pump site.

Fig. 8.—Ground-water curves for 1915 (wells 19, 20, and 21). 
During August a gradual lowering of the water table is observed, it 
being lower on each succeeding week than on the previous week. Al¬ 
though the pumping was discontinued on August 20, the curves for 
August 23 and 30 are not noticeably different in character from those 
for August 2, 9, and 16. 
The September curves are of no special interest except that they 
indicate a recession of the water table at the 6oo-foot wells to a point
