Senator Ashurst. You wouldn't have any objection to saving Arizona's life?
Mr. CHASE. Why, no; absolutely.
Senator SHORTRIDGE. Well, the Senator doesn't think that Arizona is in peril of perishing? I say, the Senator does not think that Arizona is now in any great mortal danger?
Senator ASHURST. Well, the constant reiteration of a dam at Boulder Canyon, a Boulder Canyon dam alone, does not give us very much hope.
Mr. Chase. I might say, I desire to make this statement.
Mr. CHASE. May I make this statement in a word: Having in mind the necessity for a high dam, the chamber of commerce and having in mind also the fact that a beginning is required somewhere, last year the chamber of commerce requested our representative, Captain Fredericks, to introduce in Washington, or to introduce in Congress, a bill providing for the erection of a dam at Boulder Canyon. This bill contemplated the erection of a dam 600 feet high, contemplated to be the beginning of the work. I want to rather emphasize the fact that this bill was introduced at our request by Captain Fredericks; in fact, the bill was written in Los Angeles by the chamber of commerce, and that we then had in mind and now have in mind that that was simply the beginning of the end, the ultimate end being that we should have a high dam in the southwest.
Senator JOHNSON. And your bill provided for a low dam?
Mr. CHASE. The bill provided, Senator Johnson, for a dam that would be 600 feet in height.
Senator Johnson. Well, it provided originally for a low dam, the bill that was presented by Captain Fredericks?
Mr. CHASE. Provided for a dam that would carry a superstructure for a dam 600 feet in height.
Senator Johnson. Oh, provided that you might ultimately have a superstructure after building a low dam?
Mr. CHASE. Yes; but having in mind all the time that we wanted a 'high dam.
Senator JOHNSON. I am very glad to hear it, because I did not know that you had it in mind always for a high dam.
The CHAIRMAN. The next witness to appear before the committee is Mr. William Mulholland, who will discuss the possibilities and plans for the Colorado River aqueduct.
LOS ANGELES, CALIF., October 27, 1925. The Hon. CHARLES L. McNARY,
Chairman Senate Committee on Irrigation and Reclamation. DEAR Sir: Pursuant to your request at this morning's session of the committee that I furnish records of the run-off in the Mono watershed, I herewith sumit the discharge sheets of Rush and Levining Creeks, the two main streams in the Mono Basin, for the years 1924 and 1925.
From the report of Louis C. Hill, J. B. Lippincott, and A. L. Sondertgger, consulting board of engineers, submitted August 14, 1924, on the water supply for the city of Los Angeles, I quote as follows:
The flow of the streams in Mono Basin from Levining and all creeks south thereof would deliver a safe supply of about 180 second-feet, equivalent to 130,000 acre-feet each year. The result is practically the same for the 50-year period ending September 30, 1921, as for the 9-year dry period ending September 30, 1924. In order to guarantee this continuous flow of 180 second
feet it will be necessary to provide a hold-over storage reservoir or reservoirs baving a capacity of about 150,000 acre-feet in addition to regulating storage at the headwaters of these streams and in Silver Lake."
Inasmuch as there has been another extremely dry year following the report made by this board of consulting engineers, it is my opinion and the attached discharge measurements will clearly indicate that the safe reliable yield of this shed would be considerably less than the 180 second-feet mentioned in said report.
The average discharge for these two streams for the past two years, as is shown by the figures submitted, has been only about 65 second-feet. They are herewith submitted for your consideration. Respectfully submitted.
