__3__ The formation of a large public district, comprising the cities of Los Angeles, Pasadena, Glendale, Orange County cities, and such other cities as desire to join, is in process of formation for the purpose of building the necessary aqueduct from the river to the coast to supply these cities with domestic water. This aqueduct will be approximately 250 miles in length and cost around $150,000,000. Because of intervening mountain ranges, it will be necessary to pump the water some 1,300 feet. While this will be costly, a cheap and dependable source of power will not only reduce the financial burden, but is necessary to make the project at all feasible. The amount of water required by these cities is 1,500 second-feet. This, of course, will not all be necessary at once, but as these cities are growing rapidly, they must look to the future and provide for their vital necessities. To raise a full 1,500 second-feet to an elevation of 1,300 feet will ultimately require approximately 350,000 firm horsepower of electricity. This district will be an applicant for a contract for sufficient power at the dam, to handle the necessary pumping. Large storage at Boulder Canyon is ideally fitted to make it possible for these cities to procure a domestic water supply. The capacity of the reservoir is sufficiently large that there may be obtained enough storage to protect against dry years or against the upper basin States retaining all or substantially all of the flow of the river during a period of dry years. Full conservation thus effected will permit of the utilization of water for a domestic supply without impinging upon irrigation requirements. The dam and reservor also accomplish certain desilting processes essential to successful consummation of the plan of securing domestic water supply.
