Report of irrigation investigations in Utah i I'. S. J/rjt(. A<jr., (filire of Kjperi- 

 iiient iStfttioHK, Bill. 124, pp. S16, pis. 19, Jiy.'<. 2). — This is a report of investigations 

 niatle during 1901 and 1902 under the direction of Elwood Mead, chief of irrigation 

 investigations of this Office, assisted l)y R. P. Teele, A. P. Stover, A. F. Doren)us, 

 J. D. Stannard, Frank Adams, and G. L. Swendsen. The report contains tlie fol- 

 lowing papers: (ieneral Discussion of Irrigation in Utah and Irrigation from Jordan 

 River, 1)V R. P. Teele; Irrigation in I'tah ]>ake Drainage System, by A. P. Stover; 

 The Spanish Fork River Irrigation System, Ijy A. F. Doremus; Irrigation in the 

 Weber Valley, by J. D. Stannard; Agricnlture Under Irrigation in the Basin of 

 Virgin River and Court Adjudications of AVater Rights on Sevier River, by Frank 

 Adams; and Appropriation of Water from J^ogan River, by (i. L. Swendsen. 



The l)ulletin is the second of a series of reports on irrigation laws and institutions 

 of individual arid States, the first being devoted to California conditions (E. S. R., 

 13, p. 794). It also deals with the methods and results of irrigation, duty of water, 

 crop values, cost of water, and improvement of methods and practices. 



The plan followed in the investigations reported was to select typical streams in 

 various parts of the State, and descriV>e the actual conditions created by the appro- 

 priation and use of their waters. Thus, the Virgin and Sevier rivers were selected 

 in the s<juthern part of the State, the Weber and Logan in the northern part, and 

 the Jordan and its tributaries in Central Utah. In this way jiractically every feature 

 of the State's irrigation system is described. 



The distinctive features of the Utah irrigation system, as brought out in this 

 report, are cooperation in the organization and operation of canals and the time 

 method of distriljuting water to users. The principal weakness of the system is 

 that rigfits are not defined until they come into controversy. In 190.3 the State leg- 

 islature enacted a law which was drawn for the purpose of defining all existing 

 rights, and of jjroviding for the control of the aciiuirement of rights in the future, 

 thus making all rights a matter of record, giving those charged with the distri))ution 

 of water a definite basis for its division, and giving notice of the extent of exi.sting 

 rights to those desiring to obtain rights to divert water. 



The duty of water as measured under 11 canals varied from 8.1.5 to 106 acres per 

 cubic foot i)er second of water. The value of crops, as recorded for 20 localities, 

 varied from $10.93 to .|39.40 per acre. The annual cost of water per acre as recorded 

 for 2.5 canals and ditclies varied from 40 cents to %?>.

 the outflow of Utah Lake and of the pumping plant raising the water of the lake 

 into the Jorilan River and thus maintaining the flow in the latter in seasons of low 

 water. 



Preliminary report on artesian basins in south-western Idaho and south- 

 eastern Oregon, 1. C. Russell ( Wad'r Snpplijand Inig. Baper-i, B. S. (ii-ol. /Purvey, 

 Xo. 78, pp. S.J, pis. 2, Jigs. .3). — This report is based on investigations made in 1901 

 and 1902, "and contains a description of the geologic structure of .southwestern 

 Idaho and southeastern (Jregon, with special reference to the occurrence of under- 

 ground waters. The artesian basins are de.'^cribed as far as these are known, and 

 facts are as.«embled as to the provabilities of obtaining deep or flowing wells." The

 water has already been discovered, or in which convincing evidence is found that it
