It may appear that in considering the duty of water the irrigating 
season of one hundred and eighty days is too long-; that little irrigat- 
ing is done in April or September. However, it is none too Long, for 
much of the water is stored in April and represents what a cubic foot 
per second accomplishes with reservoir facilities or with a diversity 
of crops. 
A comparison of the above table with the table giving the flow of 
the river (p. 13) reveals a remarkable agreement between the averages 
as estimated and what actually occurred in 1901, showing it to be an 
average year, a conclusion which is confirmed by reports just received 
from the superintendents and commissioners. 
Allowing for the average amount of water escaping from the district, 
we have 150.508 acre-feet used and 18,287 acre-feet waste, giving 
168,820 acre-feet as the discharge of the river, as compared with 171.1 1".> 
acre-feet, the average for six years, as given in the discharge table; 
also L09,033 acre-feet used for direct irrigation, as compared with the 
average of 100,271 acre-feet; 41.5(H) acre-feet stored, as compared 
with the average of 43,170 acre-feet. In the table the Rist Ditch is 
given as diverting a total of 9,900 acre-feet, while using but 3,600; 
the difference, 6,300 acre-feet, was stored in Mariano Lake, and is 
accordingly charged to the Home Supply Canal, making its total 
28,382 acre-feet instead of 22,082 acre-feet, the quantity diverted. 
The duty of water, it will be noticed, for the district i- l v 7 acres per 
cubic foot per second, running one hundred and eighty days, and the 
land was covered to an average depth of 1.9 feet. If we add the 
amount of precipitation on the land, the total depth would probably 
be nearly 3.5 feet. Rain, however, does little good, since the greater 
part comes as light showers. Therefore, it is more to the point to con- 
sider simply the amount of water spread on the land.
