IRRIGATION INVESTIGATIONS. tl 



The liivofost oxponditurc in any State is being made in California, 

 the work \w\ujt curried on under the direction of Prof. S. Fortier, 

 until recently the director of the State experiment station of Montana. 

 Associated with Professor Fortier in this work are Prof. J. N. LeConte, 

 A. 1*. Stover, and J. F. Roadhouse, of the University of California. 

 The field investio-ations in pumpinjr are under the direction of A. J. 

 Turner. 



In ()re<,'-on the held investigations are being carried on hy Prof. 

 »T. Withycombe, director of the Oregon Experiment Station. 



In Washington, Prof. (). L. Waller, irrigation engineer of the State 

 Agricultui-ai College, at Pullman, has charge of the field work, and 

 was assist(>d in 11M)3 by S. O. Jaynes. Professor Waller measured 

 the water diverted from the Yakima River in order to determine the 

 general duty obtained, the amount needed to satisfy the rights already 

 acquired, and the amount available for future extension of irrigation 

 along this stream. It is an important work and justifies a larger 

 expenditure of funds than this Office has been able to provide. The 

 lack of funds, however, was largely overcome by the energy and 

 economy which distinguished the management of Professor "Waller 

 and his assistant. 



The work in Idaho was under the direction of A. E. Wright, one 

 of the assistants of this Office, who worked in cooperation with the 

 State engineer's office in a stud}' of seepage losses in the valleys of 

 the Raft and Lost rivers. 



In Montana the work was carried on under a cooperative agreement 

 with the State experiment station, Prof. J. S. Baker of the station 

 having personal charge. It included studies of the dut}'^ of water 

 along a number of streams and the beginning of an investigation to 

 dot(Minine the l)enefits of winter irrigation and the best means of 

 utilizing small (juantities of water in some of the districts where 

 agriculture can be successfully carried on most of the time by rainfall 

 alone. 



In Utah the field work was carried on in cooperation with the State 

 engineei'\s office bv E. R. Morgan. It included the installation of 

 Humes and weirs for the measurement of water on Weber River, pre- 

 paratory to a determination of the duty of water from that stream. 

 A cooperative agreement has been entered into with the State experi- 

 ment station for a study of the most economical methods of distributing 

 and using water and for the inauguration of some experiments in 

 drainage for the relief of overflowed lands and the removal of alkali. 



The irrigation investigations in \\'voming were canned on in part 

 f)y the regular force of the Cheyenne oflice and in part through a coop- 

 erative agreement with the State experiment station, Prof. B. P. 

 Fleming of the station being in charge.
