IRRIGATION AND DRAINAGE INVESTIGATIONS. 



The organization of Irrigation and Drainage Investigations car- 

 ried on under this Office has been somewhat centralized during the 

 past year, a larger part of the work being directed from the Wash- 

 ington office. The work has continued under the general direction 

 of Dr. Elwood Mead, with C. G. Elliott as chief drainage engineer 

 and R. P. Teele in charge of the publications. Professor Fortier is 

 in charge of the Berkele}' office and of the work in California. The 

 Cheyenne office is maintained as headquarters for the work in irri- 

 gation extension in the semiarid regions, under the charge of F. W. 

 Roecling. 



IRRIGATION. 



In planning the work for the season of 1006 it was decided that 

 the work at all of the stations where investigations were being made 

 should cover certain general lines so far as possil)le, and that in the 

 future our publications should take the character of manuals upon 

 certain phases of irrigation practice and reports on irrigation condi- 

 tions and practice in particular localities rather than annual progress 

 reports. 



Measurements of the quantity of water used by irrigators were 

 made on Stoney Creek, Cache Creek, and in the Imperial Valley in 

 California; under a numl)er of canals in the State of Nevada; in 

 the Wallawalla and Umatilla valleys in Oregon; at Twin Falls and 

 Idaho Falls in Idaho; on the Weber River in Utah, and in the North 

 Platte Valley in Nebraska. In Oregon, Utah, and in tiie Imperial 

 Valle}' in California the.se measurements included i-ecords of the 

 water turned into the canals as well as independent measurements 

 of the water turned on to particular fields, the aim being to deter- 

 mine (1) tlie duty of water with the losses from seepage and evap- 

 oration in canals added, aiid (•_') duly of water with all losses except 

 tho.se from evaporation and seepage in the lields eliminated. The 

 measurements in these last-named sections weie re(inested by State 

 authorities as iiii aid in tiie piopei' sett lenient oi" water lights. 



The measui'enients in other loealities were made to obtain data 

 needed in perfecting a system of (listril)uting water- fi-om canals 

 among farmers. The great problem of ii-iigation in the West is 

 to increase the duty of water. The ultimate acreage which will be 

 reclaimed depends upon this. The (juautity of water llowing in 

 western streams can not be increased, but the acres which these
