DEPARTMENTAL REPORTS. 



Spanish Fork River by Hon. A. P. Doremus, State engineer of Utah; 

 on the watershed of Utah Lake by A. P. Stover, assistant in irrigation 

 investigations; on Jordan River by R. P. Teele, assistant in irrigation 

 investigations, and an introductory review of irrigation in Utah by 

 William E. Smythe. The increasing utilization of streams for power 

 purposes and for the domestic supply of cities and towns, added to 

 the greater needs of irrigation, makes the securing of some simpler 

 and cheaper method of settling titles to water and the inauguration of 

 a more effective system for protecting rights in times of scarcity an 

 indispensable necessity. Hence, the results of these investigations 

 are being awaited by irrigators with deep interest. 



The studies of the operation of the Colorado laws have been con- 

 tinued under the direction of Hon. A. J. McCune, State engineer. The 

 publication of his report has been delayed in order to permit of his 

 availing himself of another season's observation of the operation of 

 these laws. It will be published as soon as the results of this year's 

 investigations have been completed. 



THE DUTY OF WATER. 



The measurements of the water used in irrigation for the past sea- 

 son embraced a much wider area, a better equipment, and more satis- 

 factory results than those of the previous year. Enough time has not 

 yet elapsed to formulate any final conclusions regarding the duty of 

 water, but these studies have already shown the value of the informa- 

 tion gained as a basis for the planning of the larger and costlier works 

 which must be built in the future, a guide for the operation of canals 

 when built and the framing of contracts for supplying water to users 

 and for enabling the public authorities to properly supervise and con- 

 trol the division of streams. The location of the stations and the 

 names of the observers in charge of the studies of water duties are 

 given in the following table :
