<br />-6- <br /> <br />aore-feet for Mexioo's benefit prior to Boulder Dam. <br /> <br />" <br /> <br />(b) Mexico, under the concession whioh permitted the oonstruotion <br />of the Alamc Canal through Mexican territory, could have used an annual <br />average of about 1,500,000 acre-feet during the l3-year period prior to <br />plaoing Boulder Dam in cperation. Under the terms of the ooncession she <br />oould have used a maximum of something over 1,700,000 acre-feet. <br /> <br />" <br /> <br />(c) A detailed study of stream flow reoords fram 1902 to 1940, <br />depleted to reflect increased upstream uses during the period of the <br />record, indicate that for most years Mexico could have used from the <br />natural flow of the stream 1,500,000 acre-feet, in acccrdance with her <br />seasonal distribution of use, after the United States' uses existing at <br />the time that Bculder Dam went into operation were satisfied. <br /> <br />.. <br /> <br />(d) Less than one-half of the oapacity of Davis Reservoir, which is <br />provided for under the terms of the treaty, would be required to permit <br />Mexico to make full use of 1,500,000 acre-feet of water under pre-Boulder <br />oonditions. The construction of Davis Dam was authorized prior to the <br />negotiation of the treaty. One of its stated purposes in the authorization <br />wae to meter out water to Uexico iD the eTent that a treaty were negotiated <br />witb Moxico. <br /> <br />15. If the treaty is not ratified it appears probably that Mexico will <br />continue to inorease its uses with a pcssibility that she may construct a <br />gravity diversion structure immediately below the upper boundary, and that after <br />her uses have been substantially increased, she will ask that the problem be <br />arbitrated under the Latin-Amerioan Republios Arbitration treaty. If the <br />problem were arbitrated the results of the arbitraticn could well be more un- <br />favorable to the United States' interests, inoluding those of California, than <br />the terms of the treaty. Not only would the quantity of water be involved, but <br />the problem of quality, both with respeot to salt and silt, could be raised by <br />Mexioo. These questions are now resolved by the treaty. <br /> <br />, <br />4 <br /> <br />{> <br /> <br />._~~ <br />
