"Water stored in reservoirs owned by canal companies is used on the 
same land as the direct flow of the canals, and these areas are shown 
in another section of this report. An estimate of the acreage actually 
irrigated by the independent reservoirs is given in Table 29.

Stored water is used for irrigation during every month of the sea- 
son, but the greater part of it is used from July 20 to September 10, 
as the supply received on direct appropriations falls off. The amount 
of stored water used in 1916 and 1917 is shown in Table 30. which 
is taken from Tables 10 and 11 on pages 44 and 45. The large 
amount used in August, 1917, was due to a supply greatly in excess 
of the normal.
