Of the $174,000 spent on lands in Hetch-Hetchy, $81,306.18 were spent for 720 acres. For the exchange lands $92,457.02 were expended. 640 acres outside the valley proper were bought for camp sites under the order of the Secretary of the Interior. At Lake Eleanor private persons owned nearly all the dam sites. Now San Francisco owns about one-half and the United States Government about one-half. Here the development will be very expensive. At Cherry Valley almost everything is owned by San Francisco. Owners of property around Cherry Valley and Lake Eleanor received $1,000,000 for property which cost them approximately $100,000. The area in the irrigation districts below the dam sites is mostly included in the Turlock-Modesto district. In the vicinity of Hetch-Hetchy Valley the city owns 1040 acres and around Lake Eleanor, all in the National Park, 920.33 acres more, making a total inside the park of 1960.33 acres. In Cherry Creek the city owns 860 acres below Hetch-Hetchy, in Hog Ranch 322.45 acres, and in Ike Dye Ranch 163.68 acres, making a total of 3406.46 acres. Secretary Ballinger, in 1909, requested the matter be taken up de novo. At the direction of President Taft a board of three army officers was assigned by the Chief of Engineers to investigate and report on the subject of water supply for San Francisco as bearing particularly upon the need of the sources of the Tuolumne for San Francisco. This board of engineers was appointed in 1911 and consisted of Colonel John Biddle, Colonel Spencer Cosby and Colonel Harry Taylor. It occupied two years in a thorough investigation of all available sources of water supply for San Francisco and made a complete, detailed report, February 19, 1913. This board testified at length before the Committee on the Public Lands of the House of Representatives in its hearings on the Raker Bill. The statements of its chairman, Colonel John Biddle, formed the most exhaustive, detailed and apparently accurate testimony there given upon the available water supplies for San Francisco.
