THE IRRIGATION AGE. 



NATION AND STATE JOIN 

 FORCES. 



Cooperation between United States 

 Geological Survey and State of Cal- 

 ifornia in Topographic Mapping 

 and Investigation of Water Re- 

 sources. . ;J 



One of the strongest evidences 

 of the practical value of the work 

 of the United States Geological 

 Survey is furnished by the fact that 

 many of the states have appropri- 

 ated money with which to assist 

 in its investigations, under co- 

 operative agreement. The people 

 of the states are desirous of secur- 

 ing the results of the Geological 



Survey's work at a faster rate than 

 they can be furnished with the ap- 

 propriations provided therefor by 

 Congress. Instead of using the 

 funds to carry on independent in- 

 vestigations of the same kind, the 

 states apparently realize that it will 

 be better for them to make use of 

 the equipment and qualified corps 

 that the Geological Survey has ac- 

 cumulated and established for such 

 work. In every state in which co- 

 operation has been maintained the 

 saving in expenditure and the re- 

 sults accomplished have been so 

 great that the desirability and prac- 

 ticability of the arrangement have 

 been proved beyond question.

Among the states which have in 

 largest degree availed themselves 

 of these co-operative opportunities 

 is California. Under a general act 

 the state has made a continuing ap- 

 propriation, which provides $15,000 

 annually for topographic mapping 

 and $9,000 annually for the investi- 

 gation of stream flow and under- 

 ground water resources. This work 

 is carried on in connection with the 

 regular Geological Survey work 

 under co-operative agreement be- 

 tween the survey and the state en- 

 gineer. 



ADDITIONAL CONTRIBUTIONS BY 

 CALIFORNIA 



The California Conservation 

 Commission, authorized by an act 

 of the legislature to make an in- 

 vestigation of the natural resources 

 of the state, found that it required 

 information concerning the water 

 resources at the earliest possible 

 date and therefore entered into an 

 agreement with the Geological Sur- 

 vey, by which the survey under- 

 took special investigations of 

 stream flow and water power under 

 an allotment of $12,500. 



The State Board of Control 

 (Water Powers), authorized by an 

 act of the legislature to make a 

 special study of the available wa- 

 ter powers of the state and to rec- 

 ommend legislation for their con- 

 trol, likewise entered into a co- 

 operative agreement with the Geo- 

 logical Survey to compile a com- 

 plete digest of all available data 

 concerning the flow of streams in 

 the state of California and made an 

 allotment for that investigation of 

 $4,000. 



INVENTORY OF WATER RESOURCES 



The results of the work thus un- 

 dertaken are being published by the 

 Geological Survey in six volumes 

 designed Water-Supply Papers 295

IRRIGATION FLUME 



No bolts or rivets used in construction. This flume is 

 considered by experts to be the most service- 

 able equipment for the purpose on the market. 

 A careful examination of the construction as 

 shown herewith will convince those who are 

 acquainted with irrigation conditions of its 

 lasting quality and the ease with which it may 

 be put together. Complete information, with
