Second, the average amount of water in the river, year by year, before and since the construction of the irrigation canals.
Third, the most feasible method of so regulating the river as to secure to each country and its inhabitants their legal and equitable rights and interests in said water.
Captain George McC. Derby, U. S. Engineers, was ordered to report to me, and Señor Don J. Ramon de Ibarrola, engineer on the part of Mexico, was ordered to report to Mr. Osorno.
The Commission worked diligently on this investigation until November 25, 1896, when it reported its opinion that the most feasible means of attaining the ends desired was to construct the dam and reservoir projected by Mr. Follett and myself under the investigations made by the Geological Survey, provided Mexico could be protected in some way which would prevent the taking from the Rio Grande by dams and water storage of water to which she had prior right. I was authorized by the Secretary of State to formulate with Ambassador Romero a draft of a treaty to that effect, which we accomplished, submitting copies to the Secretaries of State of both nations.
The two nations were willing to consummate the proposed treaty. Congress appeared to be ready to appropriate the necessary money but, again, the unexpected happened. Making violent charges against me to the Secretary of State, Dr. Boyd demanded that President McKinley dismiss me from the Boundary Commission or he would defeat his re-election by his control of two or three western States; and threatened to horsewhip Secretary Hay if he did not do his bidding. Mr. Wilkie, of the Secret Service, reported Dr. Boyd to be a dangerous man, so he was denied further personal conferences in the State Department. (I knew nothing of this for years afterwards.) Boyd then strove to influence Roosevelt (who had become President) against me and the international dam. Mr. Roosevelt, without consulting the Commission having the project in charge, placed it in the hands of Mr. Newell, of the Reclamation Service, with directions to build the dam at Elephant Butte. After some delay another treaty with Mexico (concerning which I, though still Mexican Boundary Commissioner, was not consulted), was effected for building the dam at Elephant Butte. By the terms of this treaty Mexico is to receive a share of the water to be stored by the dam and relinquishes all claims for indemnity for the diversion of the waters of the upper Rio Grande by American citizens.
As Llewellyn threatened, there never was a "new dam at El Paso," largely owing to himself and Boyd. After twelve years, at a cost nearly four times as great as estimated for the international dam at El Paso, the Elephant Butte dam is complete; but it is doubtful whether it will ever be of any great benefit to the valleys near El Paso because of the great distance over which the water has to be carried through arid wastes. Full details may be found in my published reports under the head of "Equitable Distributions of the Waters of the Rio Grande, Vol. 2."
