The Anadarko Dam 





We here illustrate a very interesting dam 

 built for the City of Anadarko, Oklahoma, 

 during the season of 1910 interesting for 

 the reason that it is the only dam that we 

 know of that is built upon a foundation of 

 material resembling quicksand, which devel- 

 oped in the preparation of the foundations. 

 This water-bearing sand extended practi- 

 cally und;r the whole length of the dam. 



After sheet piling had been driven through 

 this material to an impervious stratum the 

 bed of the river was covered with hay and 

 straw through which were led a number of 

 perforated pipes leading to a sump outside 

 the sheet piling. On a foundation thus pre- 

 pared a concrete flooring or carpet heavily 

 reinforced with steel rods was laid and on 

 this the dam constructed. Within a short 

 time after its completion it sustained a se- 

 vere flood, the Washita River rising to a 

 point which practically drowned the dam, 

 leaving visible only a few feet of fall. We 

 show this as an example of the adaptation 

 of our individual designs to meet existing 

 conditions. 



We invite correspondence with the City of Anadarko, 

 Okla., in relation to this particular structure.

Irrigation Increases the 

 Productive ^Capacity 

 of the Soil 



Colorado presents the de- 

 velopment of the highest 

 type of irrigation. 



IRRIGATION has a tendency to 

 produce more compact communities 

 and a larger circle of neighborly life. 



The Colorado farmer produces scien- 

 tifically and economically and 

 with no } waste of effort. 



These Reasons Account for the Western [Migration of Farmers 



Our publications devoted exclusively to the agricultural resources 

 of Colorado and Wyoming along our lines describe fairly and thor- 

 oughly the results of "FARMING BY IRRIGATION."
