“That the said grantee shall not divert beyond the limits of the San Joaquin Valley any more of the waters from the Tuolumne watershed than, together with the waters which it now has or may hereafter acquire, shall be necessary for its beneficial use for domestic and other municipal purposes. “That when the said grantee begins the development of the Hetch-Hetchy reservoir site it shall undertake and vigorously prosecute to completion a dam at least 200 feet high, with a foundation capable of supporting said dam when built to its greatest economic and safe height. “That the said grantee shall upon request sell or supply to said irrigation districts and also to the municipalities within either or both said irrigation districts, for the use of any land owner or owners therein for pumping subsurface water for drainage or irrigation, or for the actual municipal public purposes of said municipalities (which purposes shall not include sale to private persons or corporations), any excess of electrical energy which may be generated and which may be so beneficially used by said irrigation districts or municipalities. “That the right of said grantee in the Tuolumne water supply to develop electric power for either municipal or commercial use is to be made conditional upon its installing, operating and maintaining apparatus capable of developing and transmitting, under a general increase in amount, not less than 60,000 horse-power at the end of twenty years. The said grantee shall develop and use hydro-electric power for the use of its people and shall at prices to be fixed under the laws of California, or, in the absence of such laws, at prices approved by the Secretary of the Interior, sell or supply such power for irrigation, pumping or other beneficial use.” The bill further provides that after twenty years the Secretary of the Interior may require the grantee to develop, transmit and use or offer for sale such additional power less than 60,000 horse-power as the grantee may have failed to develop, transmit, use or sell within the twenty years. In case of the failure of the grantee to carry out these requirements, the Secretary of the Interior is authorized to provide for the development, transmission, use and sale of such power and power not developed or used. For that purpose the Secretary “may take possession of and lease to such person or persons as he may designate” such portion of the property of the grantee as may be necessary for the purpose in view. The bill also provides that the grantee shall build certain roads and trails in and near Hetch-Hetchy Valley. III.
