full amount of their claim: and, believina: this, there was a natural disposition to prevent, if 

 possible, t!ie use of any part of this bv others. Under the present law tlie approjjriator is 

 restricted in the permit to tlie amount actually used within the time designated, and in f !iis 

 way all claim to the ownership of water for speculative purposes is averted. 



The present law is destined to be a great aid in the constniction of extensive canals. Such 

 canals renuire a considerable period for their construction and an additional time after com- 

 pletion in which to apply the water to the intended use. Under the old law there was no 

 securitv that smaller works would not divert and utilize a considerable portion of the water 

 supply before the more p.vlensive project could be brouirhf into rervice. This is not pos«i}:le 

 under the present law. An approved permit is a guaranty from the State of the following 

 facts: 



(n) That the engineer believes there is an adequate water supply. 



(h) Thatif the conditions of the approval are complied with no (|Mestion can arise as to 

 the date or amount of the appropriation. 



(c) That within the period fixed for the completion of the appropriation other apjirojiria- 

 tors will not be permitted to divert and absorb the water supply and that a limit will be 

 placed on subsecjuent appropriations, thus obviating futuie conllicts with the owners of 

 ditches for w^ hich there is no water.

The first step in acquiring a right is to apply to the State engineer 

 for the necessary blank. With the blank is sent a sheet of instruc- 

 tions, on the back of which is a sample map, reproduced in figure 1. 

 The instructions are in part as follows : 



APPLICATIONS. 



Applicatioi.3 must l>e made upon the blank form approved by the State engineer, and a^l 

 blank spaces are to be filled. Applications to enlarge eyisting ditches, or to increase the 

 acreage watered therefrom, must be made on an enlargement blank, and the entire irrigation 

 system must be shown complete from stream to end of ditch. In giving dimensions, 

 remember the following: 



"Width on top" is the width at surface water line. "Depth "is the depth of water which 

 the ditch or canal is to carry.
