Mr. S m i t h: The question "What Will Be the Effect of a Continued Drouth in the Colorado River Basin?" asl<:ed us today can be answered briefly as irrigation water will be short ':nd the farmers will lose money. Most of the farmers in this area have ha4 plenty of water for irrigation use, but some farmers in other areas of :Arizona may end up with a shortage of water. As far as the Colorado River is concerned, at the present time we have plenty of irrigation water and a little to store. The runoff water is short now and as it becomes more scarce, the gravity water will have to be supplemented from other sources. The farmers who have had plenty of gravity water to use will ha~e to change their method of farming if the drouth becomes more <::rit~cal. Water will have to be conserved in method of irrigation, and v~getation irrigated will have to be something that will best serve the area economically. Any water in storage will be allocated very sparingly. The future depends a great deal on research for supplementing the water from normal rainfall and runoff. turbines and from the standpoint of pOll sible vibration and instability at very low heads. The Arizona Power Authority is v~ry desirous of continuing the 120/0 reduction in Hoover energy available until such time as the inflows into the Lake are sufficient to raise the Lake Mead elevation to a normal level and therefore the head on the Hoover units. Mr. Men den ha 11: Although our part of the country ill not directly affected by conditions of the Colorado Ri~er, in October, 1952 we started diverting water from the Duchesne Riveli", a tributary to the Colorado River, through the Duchesne Tunnel and we get '30% of our supply from this source. Therefore, we are vitally interested and vitally concerned with the continued drouth situation on the Colora<;lo River. Our Project, the Provo River Water Users' Association, is a cdmparatively small project planned for llupplemental use only, but ~ow practically half of the water in this project is used by metropolitan v.fater districts as culinary water so we are extremely interested in drout~ conditions in this Basin. Our Project consists of the Deer Creek Dam and Reservoir. The dam is an earth and rock filled structur~ approximately 1300 feet long and 155 feet above the old river bed of tl;1e Provo River channel. The reservoir ill 6-1/2 miles long and has a I capacity of 152,000 acre feet of water. The Duchesne Tunnel brings waiter from the Duchesne River into our project and there we have an e~larged canal system for distribu- tion of water. A diversion canal brings: water from the Weber River over into the Provo River and into our teservair far use in our project. There is a pumping plant on the Jordan 'Ri ver.
