THE RECLAMATION SERVICE IN 



CALIFORNIA. 



ITS ORGANIZATION, GENERAL SCOPE, AND METHODS 

 OF PROCEDURE, WITH SHORT DESCRIPTIONS OF 

 THE LEADING PROJECTS UNDER CONSIDERATION. 



BY 



J. B. LIPPINCOTT, 



SUPERVISING ENGINEER FOR THK IRRIGATION WORK OF THE UNITED STATES GEOLOGICAL SURVKY IN 



CALIFORNIA AND FOR THE COLORADO RIVER. 



THE main office of the Reclamation 

 Service in California is located in 

 the Byrne Building, in Los Angeles. A 

 branch office has been opened at 431 Ri- 

 alto Building, San Francisco; at Yuma, 

 Arizona, and at Bishop, in Inyo county. 

 The organization is entirely under the 

 civil service, and the appointment of all 

 the men has been by competitive exam- 

 ination. 



Sacramento Valley. Mr. H. E. Green, 

 engineer, is in charge of the study of the 

 drainage basin of the Sacramento Valley 

 with a view to its development by irriga- 

 tion. His headquarters are at the San 



Francisco office. From present informa- 

 tion it is believed that during the spring 

 and early summer sufficient water is nor- 

 mally found in the streams to provide for 

 a very extensive system of irrigation. 

 The Sacramento River, however, is a 

 navigable stream, and it is not deemed 

 wise to make extensive diversions there- 

 from during the low stage of the river 

 or its tributaries in the middle and late 

 summer months. The water to be sup- 

 plied for irrigation during this low stage 

 must be supplied from storage reservoirs 

 to be located either on the main stream 

 or on its tributaries. The investiga-
