The <br />development of this area was practically completed by <br />1920, the crop report for that year showing 190,000 <br /> <br />acres lmder irrigation. Other than a small additional <br /> <br />acreage temporarily put under crop in the Volcano Lake <br />area in later years, 200,000 acres was the limit of the <br /> <br />development prior to the construction of Boulder Dam. <br /> <br />The diversion requirements of water for this area <br />have varied from a maximum of 745,000 acre feet in 1925 <br /> <br />to a minimum of 228,000 acre feet in 1932. The consid- <br />eration of the years following 1930 would not give a <br /> <br />proper picture, owing to the reduction in acreage caused <br /> <br />by the economic depress:i.on of the thirties.

In other words, <br />under what might be termed full development of the <br />class (a) area, an average of 600,000 acre feet per year <br /> <br />was sufficient to meet the irrigation requiremonts. <br /> <br />Therefore, it would seem that if in the futuro Mexico <br /> <br />were to receive a delivery of 600,000 acre feet as and <br /> <br />- 14 - <br />
