<br />32 <br /> <br />o <br />w <br />CJ1 <br />o <br /> <br />Senator Millikin. Now, driving to the point of salin- <br />ity, the testimony shows that when the Colorado has <br />become an equated stream the upper States will he <br />using and reusing water and that that hy the naturc of <br />such usage will make return How. 'I'he testimony <br />shows that in Colorado, for example, we will have more <br />land when the stream is fully equated, 'Rllh;ject to irri- <br />gation, than we will he ahle to irrigate, hecause we will <br />not have enough water, and, therefore, to hring the <br />maximum amount of land under irrigation we shall <br />have to make some use of return How. ' '1'he testimony <br />has shown that as you increase the use of the return <br />How you increase thc salinity of the water. Is there <br />anything in the [Colorado River] compact that pre- <br />vents our passing to Utah whatever salinity there may <br />be in the water as a resnlt of that consumptive use 7 <br />Mr. Acheson. Not to my knowledge, Senator. <br />Senator Millikin. Utah, in tnrn, will take that water <br />that we send across her borders and for the same rea- <br />sons she will make the same use of retnrn flow and <br />thns increase the water's salinity. Is not that reason- <br />able 7 <br />Mr. Acheson. Yes. <br />Senator Millikin. That water, with its increased <br />salinity through the nse and rense of retnrn flow, will <br />find its way into Lake Mead where it will be as saline <br />as it was when it entered Mead Lake, and it will leave <br />Mead Lake in the same saline condition, and from <br />there it will pass to Nevada and to Arizona and to Cali- <br />fornia, where it will again be nsed and reused. I am <br />speaking of retnrn How. 'I'hns the water finally gets to <br />the :Mexican border. Is there anything in the compact <br />that puts a ceiling as between the States on the salinity <br />of the waterf <br />. Mr. Acheson. Not to my knowledge. <br />Senator Millikin. Do you know of any international <br />principle that should keep ns from giving Mexico the <br />water with the salinity that it may have as it has nor- <br />mally developed nnder our own consumptive use 7 <br />Mr. Acheson. No, sir. <br />Senator Millikin. Could we give Mexico a better <br />claim, so far as pure water is concerned, or fresh water, <br />than we have among ourselves7 <br />Mr. Acheson. No, sir. <br /> <br />. <br /> <br />. <br /> <br />1:'-( <br /> <br /> <br />-...,.--~","~"'^","""'~-'"'' <br /> <br />.._"~~-~-~'~_._'-...--~-~-'---'-_.~.._~,.....,.~ <br />
