The amount of storage required for any particular canal depends

times throughout the season and on the kinds of crops grown. This 
is shown by data for 1916 and 1917 for the four largest canals of the 
valley in Table 32. The comparatively small amount of stored

supply was short and more reservoir water could have been used to 
advantage.
