 Water 

 Duty 



We are in receipt of a number of 

 letters touching on an editorial 

 in July IRRIGATION AGE on the 

 duty of water in irrigation. One 

 of these is from Mr. Henry D. 

 Tudor, counsellor-at-law, Boston, Mass. Mr. Tudor 

 in his communication presented in another col- 

 umn of this issue states that he owns an irrigated 

 farm of 160 acres in Southeastern Colorado, and he 

 is therefore much interested in the subject of water 

 duty. The gentleman says further that Professor 

 V. M. Cone of the Colorado Experiment Station 

 in an address at Fort Collins some years ago made 

 the assertion that nine inches of water is enough, 

 while John A. Widtsoe, president of the Utah Agri- 

 cultural College, Logan, Utah, in Bulletin 117 gives 

 a very interesting discussion on the duty of water, 

 in which he says: 



"The duty of water depends in part on 

 soil conditions. The investigations that 

 we have made make it clear that the best 

 quantity of water to be used for the various 

 crops ordinarily grown is between 10 and 

 20 acre inches. The best quantity lies 

 nearer, probably, the former figure. It is 

 doubtful if more than two feet of water 

 are ever justifiable, especially where the 

 rainfall is between 12 and 15 inches. Twelve 

 inches would undoubtedly be better." 



Mr. Tudor goes on to say that Colorado, being 

 one of the earliest parts irrigated, shows more 

 plainly than many other districts the ill effects of 



over-irrigation as thousands of acres in old irri- 

 gated sections of that state have been abandoned 

 because of water logging of the land, and this is 

 especially true of the San Luis Valley, where there 

 are many abandoned farms that would be produc- 

 ing crops today were it not for this condition. 



This subject is of such great importance that 

 we are producing in this issue an article by Mr. 

 Granville Lowther, North Yakima, Washington, 

 on "Important Questions for Irrigators," wherein 

 this subject is covered in a comprehensive and in- 

 teresting manner. 



The gist of the whole question is to learn the 

 minimum of water to produce the maximum crop 

 and thereby avoid water logging either your land 

 or that of your neighbor, the latter being in a sense 

 the greater crime of the two. 



Washington 

 Water 

 Code 

 Conference 



Sometime ago Mr. W. M. Street, 

 of Seattle sent a letter to ten of 

 the leading men of his city, who 

 are in one way or another inter- 

 ested in irrigation, asking them to 

 meet at the Arctic Club of that city for luncheon, and 

 the call stated that the purpose of the meeting was 

 to start a movement to frame a water code for the 

 State of Washington. 



These men appointed a committee of five, of 

 which Mr. Street was a member, whose duty was 

 to "start something." This committee interviewed 

 the Governor, with the result that he sent out over
