<br />. <br /> <br />"Mr. TIPTON. There are those two differences in any stream system-- <br />opportunity for reuse from a physical standpoint and the character of water <br />from a quality standpoint. The water I am talking about now, except from <br />the Phoenix area, would be good water. You must understand, Senator, <br />that none of the water that the lower basin will get from the upper basin <br />under ultimate conditions will be virgin water. It will have been used <br />and reused many times bcfore the lower basin gets it. The lower basin <br />will have the opportunity to use it. It will still probably be of a quality <br />which will permit its usc." <br />* * * <br /> <br />"The statement has bcen made that there is not one drop of return <br />flow returning from ccmtral Arizona at the prcsent timc. That is a fact. <br />There is no return flow from central Arizona getting beyond what we <br />call the Gillespie Dam, and there is very littlc return flow getting down <br />to Gillespie Dam. How can anyone conceivc under that condition that <br />if any water is brought into the area now, and there is much more land <br />than there is availablc watcr supply, there can be from that water any <br />return to the main stream? That is the question. <br />"As I have said, central Arizona is overdeveloped. The Salt River <br />project aiong about--and you can correct me, Senator, if I am wrong <br />on dates. I think along about 1928, possibly, a little before--maybe <br />1924 or 192 5--the Salt River area began to become seeped. The water <br />table rose. Substantial areas of land began to detcriorate to the point <br />where it appeared that thcy might have to go out of cultivation. <br />"Senator McFARLAND. I do not think you could pick an exact date <br />on that. <br />"Mr. TIPTON. It was progressive. <br />"Senator McFARLAND. Progressive. <br />"Mr. TIPTON. It appeared that the most practical means of taking <br />care of the situation was by pumping. A number of pumps were installed <br />by-the-Sa-Ict-River-Wat-er-BseI's-Associati'On-;-There-wa'san--:imm-e-d tat-e <br />response to the pumping. The water table bcgan to recede. The danger <br />from the seeped condition bcgan to disappear. Therc were being pumped <br />about 150,000 acre-feet of water. <br />"Immediately there came into being a new irrigated area west of the <br />Agua Fria, the Agua Fria being a river that runs along the west side of <br />the Salt River area. This new area was organized under the Arizona laws, <br />was called the Roosevelt irrigation district, and has some 35,000 acres <br />in it. That district contracted with the Salt River Association to take <br />over the pumps, maintain thcm, and reuse thc pumped water, so that <br />that water which otherwise would have been return flow is now being <br />reused in Arizona. Pumping is now taking place on the Roosevelt irri- <br />gation district area, and the return flow is being reused a second time <br />in that area. <br /> <br />-21- <br />
