IRRIGATION INVESTIGATIONS. 35 



The table gives areas for 10 States and none is given for 7 States, 

 but the 10 States for which areas are given contain much more unir- 

 rigated hinds under ditch than the others. However, Arizona, !Mon- 

 tana, Nevada, and AVyoming contain hirge areas of such hind, the 

 report on irrigation in Wvoming containing an estimate of 800,000 

 acres now in process of reclamation, while the Dakotas and Oklahoma 

 do not contain large areas under ditch. We have not sufficient basis 

 for an estinuite of the area in the States for which no figures are 

 givGn, and it is quite probable that the estimates for the other States 

 include land under existing ditches which do not supply enough 

 water for all the lands under them, but the areas in the States not 

 reported will considerably more than offset the excess areas in the 

 other States, so that the figures seem to justify an estimate of a 

 total area now^ under ditch and awaiting settlement somewhat in 

 excess of 6,000,000 acres. 



Some of the reports cited above contain estimates of the areas 

 under projects now in course of construction, without stating how 

 nnich is now irrigated. The table which follows is compiled from 

 these statements and from the reports of the Secretary of the In- 

 terior. The areas given under the States are exclusive of the United 

 States Reclamation Service and Carey Act projects:
