The 2,000,000,000 cubic yards falling a distance of 50 feet over the dam, estimating the weight of a cubic yard of water at 500 pounds, and 1 horse-power the energy required to lift 33,000 pounds 1 foot in a minute, would expend energy equal to over 10,000 horse-power for 8 hours every day in the year, and produce a constant stream in the bed of the river 26 yards wide by 1 foot deep, running with a velocity of 5 miles per hour, to say nothing of the probability that the greater part of the other two-thirds would find its way again to the river bed through the earth and air, the whole flowing in a steady, continuous stream to the mouth of the river, to be used as required at any season of the year, instead of, as is now the case, three-fourths of the entire mass of the annual flow going rapidly to the Gulf in the short period of 75 days untaxed. Estimating the amount of water required for annual irrigation at 20 inches, the water reserved for that purpose would be sufficient for 100,000 acres on each side of the river--all that could be reclaimed from the desert for 100 miles below. To carry out this project I recommended to the people on each side of the Rio Grande that they petition to the executive authority of their respective nations for the creation of a joint commission to draw up the necessary treaty stipulations to protect the work and the rights of all interested in them, the fundamental feature of which should certainly be that each nation should have the right to divert no more than one-third of the flow at any period, and that one-third of the flow should be maintained in the bed of the river; and that this international commission have charge and control of the work after completion as well as during construction. That the legislative authorities of the two nations be asked to appropriate, after complete investigation and estimates have been made, money sufficient to complete the work, probably $100,000 for the dam proper, $100,000 for the condemnation of the 50,000 acres of land to be submerged, and $100,000 for the removal of some 15 miles of the road-bed of the Atchison, Topeka and Santa Fe Railroad to bluffs above the old bed of the river, where the track now lies, subject to annual damage, and sooner or later total destruction, unless removed.
