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 actuallj'^ 

 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.
