<br />" <br /> <br />Just the Mexican water for 1943, showed loss of only 10.6 percent. <br />S6 it is my opinion that with proper maintenance and relining and <br />fixing the canals up, the losses based on our delivery points back <br />to the river will not be over 5 to 7 1/2 percent. <br /> <br />Inasmuch as the figures of use of water in Mexico presented by Mr. Dowd were <br /> <br />different from those presentcd by Mr. Lawson, Senator Hawkes wanted to know what <br /> <br />the difference was. At page 687 Senator Hawkes asked Mr. Dowd to explain. Mr. <br /> <br />Dowd stated that his companics' measurements showed 1, 100,000 acre-feet of water <br /> <br />diverted by the Alamo Canal to Mcxico in 1943. To agree with the State Department's <br /> <br />divcrsion estimate of 1,800,000 acre-feet for that year, there would have to have <br /> <br />been 700,000 acre-feet pumped from the river. !VIr. Dowd commented on this quantity <br /> <br />of pumping "Just how it has been arrived at we do not know." And further "we cannot <br /> <br />believe it." (p. 688) <br /> <br />Mr. Dowd presented testimony concerning the amount of water Mexico had used <br /> <br />prior to 1944 and to emphasizc his argument that Mexico should not be allotted <br /> <br />1,500,000 acre-feet per year he presented the results of a study which purported <br /> <br />to show that had Boulder Dum not been constructed, Mexico could not have r_GY_eiy_cd <br /> <br />even 750,000 acre-feet each ycar without suffering severe shortages. Interesting ly, <br /> <br />the study assumed that the All-American Canal was in existence (even without Boulder <br /> <br />Dam) and that it furnished an adequate supply to thc then present developed area in <br /> <br />Imperial Valley. <br /> <br />In addition to the water supply argument above noted, Mr. Dowd also stated <br /> <br />that it would be impossible, absent the treaty, for Mexico to get the water out of <br /> <br />the river for phYSical reasons. The channel meanders and shifts too much for pumps <br /> <br />and there are no adequate sites for a diversion dam. <br /> <br />-40- <br />
